Oysters - time to open up, stimulate pinning?

Hello All, Looking at trying to help my oysters start pinning. Used an arrowhead for holes, seem pretty small. The colonization looks pretty heavy, and I'm tempted to expand the holes and possibly move them to the fruiting chamber. Right now they're hanging in the colonization room with around 65 to 70% humidity and around 75 deg, almost no light and very little air flow. These are Goldens, Grey Dove, and Italians. Any thoughts?

An arrowhead is all you need. I've harvested many 1lb clusters off arrow head holes. When you use the arrowhead make sure the back ends of the blades don't go into the straw, you just want the ends of the blades to barely puncture the plastic then pull it out. That way when you pull the arrowhead out it wont pull straw out like you have. I would pull all that straw that's sticking out, its going to get stuck all inside your fruit clusters. They look like they could use a few more days. How many days from spawn are you and what was your spawn rate? The goldens will probably be done first, they might even fruit in incubation.

Hi! 16 days from inoculation, loaded up the bags 24 Aug. Spawn rate was fairly high, around 15 percent, perhaps even slightly higher. Used sandwich method, two big handfulls straw, one cupped palm of spawn. My thoughts were to inoculate a bit higher first go around to help mitigate any possible issues with contamination and give the spawn more chance to colonize. Thanks on the puncturing tip. How many punctures do you make? I've got about 4 to five in a column, four columns around the bag, so 16 to 20 holes. Bag is 3 ft tall, by 12 in flat diameter. Humidity and temp seems ok at 65% and 75 deg?

You want a hole every 6-8" or so. with a 12in layflat i would say 3 columns would be a better move than 4, 20 holes is a lot for such a small log.

Hmm, ok, I'll definitely try that next time. Have you had any experience growing King Oysters?

Yes, I've grown them on lime pasteurized straw and also sawdust, they grow well on straw logs but really like sawdust/bran and casing. You will need to keep kings cold if you want good quality, they are a harder mushroom to grow and have a higher risk of failure than other varieties. Oysters and shiitake are where i would recommend to focus on if your interested in production. The only advantage to kings is they have a higher selling price, but that comes with slow cultivation and higher risk of lost batches to bacteria outbreaks.

That's great advice. I read that grown on straw logs kings like a casing layer of vermiculite and peat, 50/50, with around 1% lime for pasteurization. I was considering colonizing in a bag, and then removing the bag and laying the log down in a plastic rubbermaid container with a casing layer. I will update on the oyster tomorrow when I check on them. Hopefully they will be pinning!

Hey guys! Great news, the rest of the oysters started pinning and the ones that were moved over last Saturday prior to visible pinning are fruiting nicely. Pics are of Italian Oysters taken out of coly chamber last Sat. Grey doves are pinning nicely and are being moved to fruiting chamber. Overall 6 bags were lost to mold. Notice the date on bags, inoculated 23 Aug, so 16 to 17 days for the Italians to colonize and 5 to 6 to fruit.

Looking good mate! Looks like your humidity is pretty good, however you definitely need some more FAE. What is your set up like? Can you post pictures of it with explanation? You are on the right track let's see if we can optimize it!

Hey Travel, Below is a pic of the fruiting chamber in my barn. It is roughly 11ft by 20ft. I have a small air conditioner in the back set at 65 deg on a temp controller. Inside I have an Idealair humidifier that can eat up .4 gallons an hour. You can actually see it sitting on the far workbench. It is now hooked up to a 55 gallon drum. The humidity is set at 92%. I am thinking about adding a box fan at the near corner to increase the FAE, as you suggested. Inside, the bags are hung up on rack as pictured above. The lights in the barn are the 6500K type 13W or 60 Watt equivalent. I may need a larger a/c unit as well. The coly chamber is in the back behind those doors. It is set up the same way, but with a pond fogger in a 5 gallon bucket instead of the big humidifier. Humidity set at 65%, temp set at 77deg. Thanks for any advice!

Here's another pic. I'm thinking of cutting a square and putting the box fan in this near corner.

Looks awesome mate! I would reccomend more than a box fan in the corner- you really need to duct an out line outside. I had just had a fan in and out of my Greenhouse and I had difficulties with FAE (not to mention my bedroom got more humid than the jungle). Once I hooked up an outtake vent funneling out the window I no longer had any FAE issues and finally started getting perfect fruits. Moving the air around inside really won't provide FAE, as I was going through a whole room's worth of air and it still wasn't fresh. I would be willing to bet simply doing that should end your problem. Also- I would recommend a high rh, your fruits look good humidity wise but honestly if you had some more you might get better fruits.
Keep us updated on all your progress and keep up the good work!

like travel said you need to work on the FAE your pins tell me that there is high co2 in there. intake fan, out take fan, set on a repeat cycle timer for 5 minutes on 10 minutes off and mess with it until you can get the most air exchange without messing with humidity levels. good luck!

Hey guys, Really appreciate the advice. Definitely going to set up supply and exhaust fans. Question on the supply: will putting a hotpod inline heater in the ducting from outdoors degrade the fresh air quality for FAE purposes? So, will heating outside air have any negative effect on it? Winter is Coming....hehe. I live in NH, so it'll be freezing temps soon.

look up an HRV, all new houses that are built - in Canada at least - have to have one. they bring in fresh air and take out stale air but the air system transfers the heat to the colder air. quite the system, but for those of us with the winter blues it will make a difference. https://www.amazon.com/Panasonic-FV-04VE1-WhisperComfort™-Ventilation-Patent-Pending/dp/B000XJNZ1Y/ref=sr_1_4?ie=UTF8&qid=1474192872&sr=8-4&keywords=HRV something like this.

Checked out the unit, will look into getting one. I have some pics of the Italians and Grey Doves fruiting and harvested. Anyone have any comments on the fuzzy bottom of the stems? More fresh air? The taste was very delicious, though.

Those are some huge fruits mate!

Does look like they could use some more FAE though, getting a little long in the stem, and yes as you mentioned "fuzzy feet".
Your humidity levels look spot on though 
Also, it looks like you harvested them a little on the late side for choice quality- though perhaps that's on purpose for your market?

Those are all about a day past prime, pick much earlier. Are you directly misting? You should be 2-4 times a day minimum. As well as not enough FAE it looks like you a bit dry as well.

Hey guys, appreciate the info. It's been a busy week and a half or so. Yeah, fuzzy feet, hehe, I like that. Yep, they were a bit past prime, picked the new ones earlier. So, I installed fresh air supply and exhaust with inline booster fans. Supply line has a hotpod unit inline as well. It is already helping immensely. Water vapor is not pooling up on the cement floor, and within a day and a half the majority of bags started pinning a second flush. The mushrooms were a bit waterlogged without the air flow too. This has solved that issue as well. You guys have helped a lot, thanks! Check out the pics! I think the pins on Grey Doves and Italians look a lot better. These are second flushes. Check out the exhaust flex ducting, how I put it near the floor. I found this to help a lot with pooling water vapor.
