fruit question

this is my first grow so bare with me here. i have 8 PF cakes in my fruiting chamber right now (shotgun chamber) and only two of them are fruiting. They have been in there for about 3-4 days now. the two that are fruiting only have one solid mushroom coming out of it. all the pictures i have seen have shown a considerable amount more per cake. i can't help but think i am doing something wrong? i do light misting 2-3 times a day and fanning for a good 10 minutes about 5 times a day. the perlite is wet but for some reason not creating that much humidity. there is no moisture on the walls of my chamber and my hygrometer reads only 70%. heres a picture of what the best fruit looks like at the moment

you can also check out my grow log, theres a link in my sig. any advice would be much appreciated.

first of all I wouldnt worry too much yet, cakes can be in the FC for a week or two before they start to pin
but it does sound like youre over fanning. just fan after every time you mist. and each time you fan, it only has to be for about 1 minute. If your hydrometer is only reading 70 youre definitely fanning too much/too often
If the perlite is hydrated correctly and youre misting/fanning the proper amount you should have no problem staying above 90% rH

Yeah, what type of fan are you using? 10 minutes with any sort of electric fan would be way overkill--mushrooms need fresh air, but not like... wind. If I understand the purpose correctly, the goal of fanning is really to just replace the stale air in the chamber, which can be done very quickly. 5 times a day for 15 seconds should do the trick and won't dry out your perlite.

yeah its to replace stale air and to help evaporate the water you just misted onto your sub

Fanning after misting creates evaporation, witch is known to be the pinning trigger No.1.
After the pins are set you dont need to fan an proper tweaked SGFC. You just have to replace the moisture that evaporates or that is pumped into the fruits.
And yes an e-fan is overkill.

thanks guys. ive been getting a lot of conflicting information but this really helps. i am using an electric fan. I was using just the lid of the chamber to fan for a while but it appeared my mushrooms were getting water logged.

at the beginning i wasnt aware that i needed to fan (which is how they got water logged) and it was still reading 70% and there was still no moisture on the walls of the chamber. could it be because the light i have is producing heat and evaporating it?

Are you using a digital RH meter? If so you can pretty much just toss it out as they are very very inaccurate. If you have built your SGFC to spec it should be providing 90%+ RH. Also just because you do not see condensation on the plastic does not mean anything. Condensation on the inside of a SGFC just shows that there is a temperature differential between the ambient air and the air inside the chamber, it does not relate to relative humidity.

its not digital, but the only one i could find is a cheap one from home depot or something. its all i could afford at the time so im guessing its not 100% accurate.

Its prob just that your hydrometer is off, is it digital?
to calibrate your hydrometer, wrap it in a damp/wet towel for an hour or so. If its not at 99% at this point, set it to 99% so it knows what the fully saturated air point is
edit: just saw that you have an analogue hydrometer, try getting a better one maybe? you can still wrap it in a damp towel to see if it reaches 99%

What sort of light are you using/how far is it from the cakes? If it's fluorescent (~15W) you're fine.

You may just need to calibrate it, if there is a setscrew on the hygrometer you can wrap it in a moist dish cloth for an hour or so. Unwrap it and then turn the set-screw to 100% RH and you should get a more accurate reading.
Some meters do not have set screws and tend to be inaccurate.
BUT like I said earlier, if you build a SGFC to spec you will have the proper amount of humidity to provide the proper parameters for your mushrooms. Holes on all 6 sides, 4" of moistened perlite, etc.

its an agromax F54T5HO 54 watt. i had posted this information on a lighting post and they had said it was fine. its sitting about a foot above the chamber

it does not have a set-screw so im guessing its pretty much useless. i did build the SGFC to spec. so hopefully everything is fine. only time will tell. i did harvest some mushrooms from a cake already but only three grew out of it which is what made me start this post

Hmm, that's hotter than anything I've personally seen recommended on this site- not to say that it's TOO high, but it could potentially be a factor in your humidity problem as well. I really think cutting back on the fanning will help a lot though, and 3-4 days is really not a long time in the FC anyway. Just mist and fan lightly a few times a day, if you aren't getting more pins/fruits in another 5/6 days or so I'd dunk and roll again. It's actually time to harvest the one you posted

Yeah, that whole growth that's wrapping around the cake should come off with it. Now you'll have a good purpose for that electric fan!

now that ive harvested that one off that cake, can i leave it in there to see if it will pin anymore or should i just dunk it again?

I'd just leave it in there for now to keep all your cakes on the same cycle. If it fruits again with the rest of them, great- and otherwise no harm done, you can dunk em all again for the second flush.
I think sometimes a couple jars might colonize faster than others (maybe due to slightly disproportionate inoculation), and if you birth them when a couple are DONE and the rest just LOOK done, you end up with this type of situation where some cakes are still colonizing the substrate while some begin to pin/fruit.

ahh okay. i was told to leave the jars sitting for a week after they are 100% colonized, which is what i have been doing with the exception of the cake pictured because it started pinning in the jar and got like 1 1/2 inches long so i went ahead and birthed it and stuck it in there.
