Requesting help growing five basic strains in a grow tent. Pink, yellow, blue, and king oysters. Chestnuts too.
    #26897800 - 08/24/20 08:21 PM (3 years, 5 months ago)

First off, this is all in my farm house basement.  Grow tent is 60°F and 95% relative humidity. This is all in a 137ft³ grow tent with a 4" exhaust fan rated at 100cfm. I thought this would mean I have a fresh air exchange in the tent at 43.8 air changes/hr based on air changes= ((CFMx60minutes) / volume of tent) or ((100cfm x 60 minutes)/ 137ft³).

I think my best bag of pinks all aborted. I need help determining if the yellows/goldens are ready for harvest. I'm trying to make these conditions work for blue oyster, yellow oyster, pink oysters, chestnut, king oyster, and eventually shiitake. I dropped temperature for about 2 days to 54°F, and I wonder if that hurt the pinks. The yellows seem unaffected. I was trying to get the kings to fruit. They haven't yet.

These were all cut open 1 week ago tomorrow. The chestnut substrate had a cut added to induce pinning at that cut 2 days ago. This is also when humidity setting was raised from 92% to said 95%.

I'd appreciate some advice on whether this setup will allow me to walk the line and fruit all these varieties or if the parameters won't satisfy them all.

I thought a lack of light could be the issue. I resituated my large shop lamp right on top of the tent though.

Are the blocks drying out somehow? Do I not have enough light? Do you need to see more pics of my ducting to determine if there is enough FAE?

You definitely need more FAE. With oyster long stems = you need more air exchange.

The yellows have been ready to harvest for a while. You want to harvest before the caps start to turn up. Do you have a circulation fan going? A circulation fan will keep co2 from building up around the mushrooms so you will need less FAE.

You're not going to fruit all those species at the same temperature.  Pick cold or warm and fruit the species that go with the temps you can get.

Thanks for the reply. So on top of an exhaust fan I should have a little fan inside the chamber? The humidified air blowing into the tent doesn't do this? As an experiment I took two bags of blue oysters and set them outside the tent in my basement. I've been spraying them maybe twice a day with the water bottle. They're long and stemming too. Could it be that my basement has too much CO2 in it? I asked my friend who's in HVAC if he thought it was possible that the air in my basement had over 800 parts per million CO2. He said that was highly unlikely. He can get his hands on a CO2 tester and was going to do so, but that doesn't help me right now.

Here are some more pictures of my exhaust leg. The fan is at the end, closest to the outside inside the board that is in the window. It's drawing through the leg that is attached to the tent and not pushing through it to the outside.

Something I have noticed is that although this fan is rated to move a hundred CFM, it never seems to have any effect on the amount of air in the temp. The house of hydro Mr fan blows the tent up like a balloon while humidifying, but this exhaust fan doesn't suck it tight when that's not running. I know there is a difference between fans that move pressure and fans that move volume, but I thought I would note that. I'm wondering if my exhaust legs are set up wrong.

I bring all these observations up as points to help me troubleshoot.  Here are the latest pics from yesterday. This latest batch of pinks (aren't even fruiting. They had some primordia in the bags before cutting, and that was 2 days ago. There aren't any pictures of those. just the spent blocks that I cut all the aborted pinks off of.

As far as not being able to grow all these species in one room, I thought I could walk the line with the temperature that is in all their supposed temperature ranges. The temperature in the tent ranges from 60 to 68 degrees Fahrenheit. I also have an air conditioner plumbed into it to through a black tile. There is a return to get the air out of the tent and cool only it. In other words, the AC is only circulating air that is in the tent. I've barely used it though.

I thought the only issues with temperature I might see would be with getting the kings to pin. I also thought I might have issues with blotch on them, but from reading on the internet 60 or even 68 degrees Fahrenheit is in all the oysters' temperature range.

You need way more FAE. How big is that tent? I don't see a circulation fan in your tent either. You need to keep the air moving so c02 does not build up around them don't have the fan blowing on the bags. You just want air moving constantly.

Part of your problem is the piping. you want to use smooth pipe if you can. If you can't then you need bigger pipe and a stronger fan. The wire in the pipe slows down the air tremendously. When I installed ductwork we never used flex pipe unless it was totally necessary. Because it slows down the air too much.

I edited this. Sorry, I said the same things. But none the less they are true.

Yeah I guess you might be able to pull it off with those temperatures.  I just think you might run into issues, I'd pull the tropical species out and focus on the colder ones if it were me.  Pinks yields suck anyway they're mostly a novelty species.

Thanks a lot. The tent is 137ft³.  I went with the flexible duct for the ease of install. I see your point though. The calculations, formulas, and calculators on engineering toolbox deal with air flow through smooth galvanized pipe. Head loss and velocity will greatly increase and decrease respectively with a higher coefficient of friction that this flexible ducting brings.

I had an old junk 8-in inline duct fan. I installed it and checked the 8-in inlet with an annemeter. The CFM was around 600! The tent was expanding though. I don't know if something is wrong with this fan or if it's because I had it reduced down to 4 in right on the other side where it goes out the house in the 4in dryer flexible duct and house cover. If I took a light piece of paper at different points across the diameter of the fan's outlet that was reduced down to 6" the paper would blow out as it should, and in other spots it would suck in. This is on the same side of the fan at different points across its diameter. It really baffled me. I purchased another fan off Amazon that isn't 60 years old and will try it.

how do you guys handle air circulation inside the tank? I put an old desk fan in there for now and it's just blowing across the length of the tent. I'm not sure how long it'll last since it isn't made for such a humid environment, and I hope it doesn't burn my house down from blowing a break or something if it does short!

Finally, The two bags of blue oysters that I placed outside my tent had just pinned with little clusters when I removed them from the tent and put them in my still basement air. These are pretty long and stringy too. They did not have a fan on them.  I see pictures of these DIY box kits growing beautifully though and they're just sitting on people's kitchen counters.  Could I have a CO2 problem in my basement somehow? It's an old farmhouse that isn't completely airtight in any way and I would think that the HVAC system would be drawing and moving some air out of the basement by itself. Even without this though, as I mentioned before, my HVAC buddy said it was unlikely that CO2 and my basement is over 800 parts per million. Humidity is very high in my basement where these two bags were placed at 70 to 80%, but it is not the 90 plus that these oysters might need.

Duly noted. Thanks for the reply. The few that I ate did taste good though! They didn't entirely lose their color through the cooking process like I had expected in red on the internet too. This helps makes for pretty dishes

Update: my HVAC buddy stopped by with his C02 meter 0 ppm C02 in the basement. 0ppm in the grow tent. With 0ppm in the tent, even without adequate FEA shouldn't I be getting good fruit? This goes back to good fruits forming on people's counters in the boxed grow kits. They don't have fans on the mushrooms but they grow right.

You need a circulation fan in the room co2 is building up around the mushrooms. Trust me long stems = you need more FAE. I believe I already said this but it may have been another post you want to pull air out of your tent and not blow air in. You are creating positive pressure in the tent...



The intake air hole is just a hole air is drawn in because of your exhaust fan. I used a flapper because it will close the hole if you turn off the fan so humidity will stay in the room longer. My fan stays on 24/7 so I really did not need the flapper.

That desk fan will not cut it for a circulation fan. Like I said you need the air moving in your tent. It doesn't have to move much but it has to move in all parts of the tent. You can use an incense stick or anything that makes a little smoke so you can see the air is moving. I use my vape and blow it through a straw.

Thanks a lot for the reply, all the detail, and the awesome diagram. As far as the air intake, won't the exhaust fan be drawing in from the 4" duct where the fog is coming in at? Do you think that will suffice?

I ordered two of these for my tent

https://www.amazon.com/dp/B009OWRMZ6/ref=cm_sw_r_cp_apa_i_WTXrFbMQX3ZH7

I think I'll put them at opposite corners facing the inside of the tent. I'll put em in the top corners and face em downward. I order a better 4", a 6", and an 8" exhaust fan. I'm certain the 8 should be overkill and really need to get this working with a 4". It's 137ft³ that I'm dealing with. I might step up to the 6" so I never have to worry about it. Perhaps my biggest issue is this air circulation though.

The C02 check made me feel more at ease. I know now I can change my setup and equipment a little to get things working. If I had high C02 levels in my basement there would be a lot bigger issues going on than me trying to grow gourmet mushrooms.

Thanks for the help. I do appreciate it, and I hope to hear more from you all.

Those little 4 inch fans will do nothing in my opinion...

https://www.homedepot.com/p/Hessaire-300-CFM-Silver-Electric-Powered-Wall-Mount-Electric-Attic-Fan-8SFV-H/309263793

You might need a speed controller for it. Mount it at the very peak of your tent then you will have no problem with air circulation

I use a 4-inch inline exhaust fan for a 280 cubic foot room. I leave it on 24/7. I would like to have had a 6 inch which I actually ordered. But I got a 4 inch It was a really good deal from eBay so I didn't complain.

Yea the exhaust fan will probably draw air from the 4-inch duct. You will have to decide if it is enough air. It depends on if it is getting restricted in some way. Remember you can't have too much FAE.

So I am just puttering around setting up my shed to grow in officially and came across this fan since I have to buy another fan since I can't tear down my current setup to setup the shed https://www.amazon.com/VIVOSUN-Inline-Ventilation-Variable-Controller/dp/B01CTM0LLO/ref=sr_1_8?crid=5QCQMB5IF4K4&dchild=1&keywords=inline%2Bfan%2B6%2Binch&qid=1598527339&sprefix=inline%2Bfan%2Caps%2C564&sr=8-8&th=1 I have the 4 inch version and it works great. And it comes with the leather casing which can help with noise reduction but also condensation. Which condensation in the pipes is a pain as I am struggling with that right now in my current fruiting chamber. But my shed shouldn't have that problem because it will be a different configuration. And this fan will get you 1 air exchange per 2 minutes. :thumbup: :thumbup: 740 CFM x 2 =1480 square foot. Which is slightly larger than your fruiting chamber so it would be every 2 minutes your air would be exchanged. Which is what you want.

This video breaks down ventilation very very well in detail including all the math and Why.

Enjoy!

I wonder if the cheap duct 4" fan I got really moves 100cfm. Again, my tent is only 137ft³.

I ordered this fan for circulation too https://www.amazon.com/dp/B07P6VNMV7/ref=cm_sw_r_cp_apa_i_b28rFb0KVQYED

I'll open them up and choose which I think is adequate.

Should my humidity be dropping in from the top? I have the humidity dropping in the top very close to center. The exhaust is an 8" opening that eventually necks to the 4" exhaust fan. It is at the top of the tent on the opposite end as the humidity entry point.

Sorry everyone had another sugar episode. Let me explain how I did my tent. My tent was smaller but everything works in the same way. This will take some trial and error to get it right. That is why I suggested the speed controller and the attic fan. The reason I suggest an attic fan is they are rated for moisture. I took a bathroom exhaust fan and appointed it up at the peek of my tent. my fan blew out quite a bit of air but by the time that air hit the peek of the tent and blew air down the slope of the ceiling of the tent the air slowed down and was barely moving across the slope. But the powerful suction will keep the air moving toward the fan so you have more of a sucking action than a blowing action (I know that's what she said). This keeps everything moving. I hope that makes sense.

As far as the condensation goes you need to set up your duct so all the condensation goes to one spot then make you a bulkhead out of PVC and have the water travel to a bucket use a condensate pump to have the water pumped to a sink or out of the house...

https://www.homedepot.com/s/condensate%2520pump?NCNI-5

Above is just an example of a condensate pump I think I paid $12 for my pump.

How to make a bulkhead at 4:15 of video...

yea right now it collects at the dip and the other person lifts and I catch with a bucket.. yum spore soup. but I am changing it soon so that the exhaust fan will be inside the FC and the piping will be too so there won't be a change in temp for the most part I hope.. right now the pipe is outside the FC and sucks all the much colder air through it with hotter air outside it..

Where ever the dip is you can put a bulkhead and have it just naturally drain into a bucket then you can just empty the bucket or use a condensate pump and never have to worry about it. Whatever you decide good luck!! You can use a PVC union at the bulkhead so if it ever stops up just unscrew the union and unstop it with an old toothbrush. I doubt it would ever stop up though.

What kind of flapper do you have that covers your intake and actually opens when the exhaust fan is running? I currently leave mine on all the time.

I have a bunch of 2nd flush blue oysters I soaked over the last couple days. They really started coming last night. They still look stringy, and I have the 4" circulation fans installed. I hung pieces of tape in all the corners of the tent, high, low, front, back, front of the shelves, back of the shelves, and everywhere in between. They all move. Yet the mushrooms still looked stringy.

All I can do is add a larger exhaust fan it seems. Remember, this is a little 137ft³ tent with a 100cfm exhaust fan. For 8 air exchanges/ hr the fan needs to move 1096ft³in 1 hour. To JUST meet that and work around the clock I only need an 18cfm exhaust fan. I bet the fan I have isn't moving what it's rated at, but I don't think it's running at less than 18% of what it's rated at.

I would think I am I taking sir through the humidifier duct. Does the placement of the exhaust fan work? I have duct connected to the tent, and this fan is outside drawing air via suction from within the tent through the duct. Does the fan need to be in the tent and pushing its exhaust your through a duct?

On another note, the shiitakes in this link are about 35 days old. They're not brown and barky, but there are lots of little mushrooms popping up in the bag. Should I cut em open, spray em with a cold hose, and let em fruit? http://imgur.com/a/JR0h8cw

They are fruiting too early. Probably due to à sudden temp changé. You should incubate at least 7 weeks. And that's strict minimum. If They fruit prématuré either the temps in incubation changed or you got à conta, bacterial or other that forces them to fruit. The bag look pretty ok though. :frenchie:

And yes if they're pinning invitro, fruit 'em, they won't stop anyway!

I missed this one...

Ok. So should I just spray em with a house outside and then throw em in the fruiting tent? I'd like to try that way . Spray em everyday after opening for 3 days.

I put a 6" vicodin exhaust fan on last night. WAY too much. Definitely getting exhaust now. Instead of running all the time now I'm going to run it 2mins on then 5 mins off around the clock.

I noticed that even though the first fan I had on was listed as a 4" exhaust fan the box says 4" inline cut fan. No suction into it can be felt like it can be on 4" and 6" exhaust fan variants I tried- ultimately opting for the 6".

I believe the impeller design id different or something and that I have never been exhausting anything at all.

I wouldn't spray them with a house. A hose maybe but not a house!!

Good thinking! That probably wouldn't help my cause.

I've had a couple second flushes of blue oysters come since installing the 6-in duct jet exhaust fan. They're still stringy. The exhaust fan is exhausting in the top of the tent and the humidification is coming in from the top. This might matter because when the exhaust fan runs it sucks the sides of the tent in and the fan for the humidification box runs. It spins freely. Really fast. The exhaust fan is drawing odds intake for the air exchange through the humidification duct. I don't think this is a problem since it has to be getting enough air I would think, but is the fresh air just blowing across the top of the tent since they are both at the top of the tent? I had the humidification coming in at the lower front corner and exhaust was going out at the top rear corner, but I don't remember why I changed that about 2 weeks ago. I'm thinking about moving it back and trying that. My two little 4-in circulation pancake fans make pieces of duct tape that I hang all throughout the grow tent flap ever so slightly. They're not flipping and dancing in the wind like it's a hurricane, but they're moving. Without having anything to compare to, I would say there is good circulation. Even the exhaust issue that I am asking about here doesn't seem like it actually could be an issue. The exhaust fan kicks on, the sides of the tent suck in, and after it's good and tight the water tote fan will start spinning. This tells me everything that that exhaust fan could suck out in the tent has been sucked out and it now has to draw intake air from the outside. That's exactly what I want. Yet I'm still seeing stringy oysters. Again, the exhaust fan cycle is 2 minutes on, 5 minutes off. It's a 6-in exhaust fan pulling from the tent with an 8-in duct. The duct is reduced down to the exhaust fans intake of 6 in. Immediately on the exhaust side of the exhaust fan it is reduced down to 4-in duct. This is about a 30-in run to the exhaust outlet of the house.

Do you have any other suggestions? Is there something wrong with my strain or the substrate?

And also, are these chestnuts ready for harvest? http://imgur.com/a/5k1WxZU

I would think you have found the problem. You have your exhaust and intake on the same level. Air and water act the same they take the path of least resistance. So what you are doing is sucking fresh air straight out the exhaust. I would suggest moving your exhaust to the bottom of the room and piping the intake air behind the circulation fan. This way you are sure fresh air is being mixed in by the circulation fan.

I think the fresh air is being sucked straight out of the room and never mixing in the room. This would happen especially if you have a smaller intake air hole and a bigger exhaust air hole. I also think those 4" fans are doing nothing for circulation. I use a 4" inline fan for my circulation fan. You want air being sucked as well as blowing. Those 4-inch fans are not making air move because of a sucking action from the fan. I have mentioned this a few times so I won't mention it again. I wish you luck and hope someone can help you figure out what is going on. But everything I have said I mentioned from the begining.

Thanks a lot for the reply. It is very hard to move my exhaust. Instead of moving it down I'll add 2 smaller 4" intakes near the bottom of the tent. I will also install the 10"Thank fan I bought at the top of the tent in the middle to move the air around. Thank you!

These are a lot better with the new exhaust fan, but do I have a lot of work to do?

Yea those look a lot better!! I wouldn't worried about them anymore. It will be hard to do any better than that. You might harvest a little earlier though.

By moving the exhaust down. I meant putting an elbow on and extending the pipe down to near the floor.

But your fruits look good now.

Are these acceptable to sell? do you think any little Asian grocery stores would buy these? Do I have to work on my quality? I let some get big and some are small to see how they would like them.

This is exactly what im trying to incorporate in my Mylar grow tent. What im having a hard time is finding a way to install this without cutting into the tent floor. How does your bulkhead adapt do your floor? i was going to raise the sides of the grow tent and allow the slope to collect the water to be pumped or drained. At this point pumping it out seems the most reasonable. thoughts?

Are you going to have shelves in the tent? If so how do you plan on the shelves sitting on the floor with the sides raised and the floor sloping?
