Greenhouse build

So I started my GreenHouse journey with this thread. It's old but still holds true
https://www.shroomery.org/forums/showflat.php/Number/13843759/fpart/1/vc/1
So I got the mini GreenHouse- rigged up a Humidibucket and two fans, one in, one out.


My exhaust fan was too heavy so I simply used some twisty ties to attach it to the shelf above

I was still having FAE issues, then SpeakSoftly and JanuaryWolf recommended venting out the window, supplied and cut the material for me (thanks you two!) and perfect FAE was finally achieved (and my room no longer felt like a swamp!).


Got a Gr0wer' Approved hygrometer

I had my intake fan crap out on me after about 9 months- granted it was on 24/7 but it was rated for high humidity. The calcification is what did it in. I'm about to start using filtered water to combat that problem with my new fan.

Odd thing was before it crapped completely out it slowed down a bit- and my humidity shot up. Apparently it was blowing too fast to effectively funnel the humid air up and into my GH. So with the new fan I got a fan speed controller to dial it back a bit.

Being able to dial it down maintained proper FAE yet instantly made my rH jump almost 15%.
Then I decided to upgrade- got a humidity controller that plugs into a second pond fogger, both now in floats (idea MorePies) as I work long hours and the bucket always ran out of water, the controller is also attached to an ultrasonic at the bottom.




And I added a fan speed controller on the exhaust, to dial it down to help retain humidity.

And just learned how to calibrate my hygrometer, using a wet but not soaking towel, wrapping it for 30 minutes, and adjusting the tiny screw (didn't have a screwdriver small enough but my inoculation loop fit perfectly!) on the back, gently- lightly, to make it 98%. Turns out mine was reading about 10% too high this whole time.
Here are recent results of my GreenHouse!


I did learn a few things from this past run- there are some serious microclimates in my GreenHouse. Appeared to stem from both the direction my intake pipe was pointing (towards the back) and air coming in through the zipper. I will be changing the way the intake blows into the chamber next- stay tuned!

rr suggest putting holes in greenhouse for increased FAE to reduce contams and co2 thats how mine is set up and it works well. also i just use a humidifier on a 15 on 15 off cycle, but if you can get a timer that does 5 min intervals thats better. the pond fogers will produce co2 which could be good or bad.

What makes you think pond foggers produce Co2? It seems unlikely..

Mostly various species of oysters at the moment- with enoki as well (probably my favorite mushroom as I cook a lot of Korean). I currently have blue, pink, gold, Phoenix, King, and two aloha isolates culture wise along side the enoki (most have not been put to grain yet).

Going to need an active exhaust and intake most likely and 24/7 FAE, no timers. Oysters need tons of fresh air for a quality fruit. THe pinks are more tolerant to low FAE but spore load is huge so you need an exhaust. Kings dont need much FAE but much higher RH than the other varieties. Take a look at my greenhouse below if you haven't already.

Thats what it said on the package on the one i had as a kid but i dont see any thing on line to support that so i guess i will have to update my prior knowledge.

Yeah I saw your grow room ( )- would a PC fan be enough for exhaust?

Yes PC fans work but they crap out after a while, 2-3 months. They are not designed for high humidity. A 4" greenhouse duct fan should work for intake and exhaust. And put at least the exhaust on a dimmer so you can trim the airflow to be slightly negative.

Just ordered fans that were made for greenhouses. They were a little pricey but shouldn't crap out
Edit: where should I place the exhaust? Top middle or bottom?

These fans put out some power- how much pressure is optimal? I'll get dimmers for both if need be.

My roommate picked up the wrong size PVC while I was at work so this isn't the final product. Also I think the pond fogger I got isn't putting out enough so I have my ultrasonic in there too for the time being.

Do you have a good hygrometer in there?

Next paycheck I'm looking at getting a T-8 light and a hygrometer- any suggestions on which one to get? I'm a hardcore Amazon shopper and while money is an issue I'm not looking to just get the cheapest possible- if I have to save for a good one I will. This is now a full time hobby for me- if I'm not at work I probably have my hands in my SAB. Also looking to make a flowhood soon too.
