critique my greenhouse set up

I am using a small 4-tier greenhouse... I plan on using a Vicks 400 cool mist inside it, with holes cut for FAE. I am using a 75W compact flourescent in a reflector dish style light outside the greenhouse. I have analog timers for lighting and humidity. Can I use a small Holmes HEPA inside the closet to help with FAE? The doors on the closet are the slat-style folding doors... should this allow enough AE without a HEPA running? I have sanitized the carpet in there, and covered with contractor bags. I plan on using a pan of perlite under the greenhouse to catch additional water.
Do I have enough lighting? It is a 75W equivalent that pumps out 1100 lumens. Can I spray my walls with a fungicide coating to deter trich and other molds without harming my edible mushrooms?

Interesting, this might work.
The light has plenty of watts- but what color temperature is it?

It is a 'daylight' color compact fluorescent.. doesn't get hot at all which is great.
I have a SGFC in there, my digital hygrom crapped out today... and i'm not sure how accurate the analog I have is, but it held at a constant 90RH while I was gone.
Is the HEPA overkill? It doesn't seem to dry my SGFC, and I already have it so I don't mind the added insurance. I want to keep things as dry as possible outside the greenhouse and will be using Oust a few times a day in the closet to keep things clean.
Pics will come soon after I get my GH in and I get it full of yummy, legal, edible mushrooms.

you can use a piece of plastic on the bottom to catch the water and funnel it into the pan. thats my only 2 cents.

Hepa inside the closet, I don't think you want. But having an oscillating fan on a timer in the room might do the trick. Those closet doors come in different styles, but they are all pretty breezy.

For FAE, have the air inlet of the vicks on the outside of the door flap, allowing outside air to be pumped in when it kicks on. You will also want to put it on a timer. Repeat cycle timers used to be had for ~$60, but you could just have it open more and let it run longer. Not sure what people do now.
You don't need the hepa filter for sure. You could have it run in the room where the greenhouse will be, but only for the fact that it will move air around. A ceiling fan will work just as well. You might just save the hepa for your bedroom.
I wouldn't spray fungicide on anything while there are fruits present. Just clean it with a bleach solution before hand, or spray some lysol on it. If you put FULLY colonized trays in there and provide PLENTY of FAE, you shouldn't have a problem.

so if the intake is outside the GH... should it be necessary to put holes in my GH?

I am at 99% RH running 1hr on/30mins off... no condensation. I have no holes cut yet, and I have the intake filter outside of the filter to pump in FA. I am using a Vicks 400 coolmist. Should I cut? Will 2 holes about 4in on each side, top and bottom, be sufficient?

Things are running great... I got it dialed in easy, and so far even what is left of my cakes are thriving in there. I give it a two mists to mimic rain and fan it out good afterwards. The humidifier does a great job at moving air around in there. I cut two holes near the top, and the bottom stays open a bit to allow room for the humidifier and co2 can make its way out. I'll get some pictures up soon. I dig this set up alot, although I feel like i'm cheating with everything being automated. I like to tinker with shit.

I'd back off on the run time of the humidifier. Believe it or not, but you can over humidify a greenhouse and in my experience it leads to contam.
Many recommend starting out with 15 min on and 1 hour off as a starting point. Sometimes this means buying a better timer, but that's usually a minor investment.
I personally do not use holes in my greenhouses. I get FAE by fanning 3 times per day. It's easy to cut holes in the plastic, but I prefer not to unless I strongly believe that it will be permanent. I'm just picky that way.

I usually have mine open at least once a day anyway, it's no hardship to just fan it out with a lid.

what are signs of over humidifying? i don't get alot of water in the drip pan, and there is no condensation on the sides.

no such thing as too much humidity. it's the lack of air exchange that'll get ya.

Yes/no. You want it below 100%, so you can get evaporation happening. Mine is set to 85%

Is this true? I would think that if there's no such thing as too much humidity, people wouldn't bother buying expensive timers and what not

In this case I guess the problem with 'too much humidity' is the condensation on the sides of the greenhouse.
You can mitigate that by tweaking your humidifier on timers sure. Or you could increase fae. Probably a combo of both.
Sure on a theoretical level if you fed the fungus nothing but fresh 99.9% saturated air, there'd be so little evaporation that it wouldn't want to pin prolifically. But it'd be perfectly content.
In practice, it takes very little air exchange to knock the humidity down.
Thats why I say there really isn't such a thing as too much humidity. You could have too much condensation, or too little air exchange. It's semantics I guess. But typically when someone new comes along and says they think the humidity is too high in their fc, what they're really saying is 'my fc doesn't have any holes in it'.

That is why repeat cycle timers are so great. You can do a 5 min on, 15 off, or anywhere in between. If the vicks is also the source of the fresh air, you want it on as much as possible, without soaking the trays/cakes. A friend had perfect results with something like 2-3 min on, 10 off. He also had a few slits in the sides of the greenhouse...
Just move as much air as possible while keeping Rh at 85-95% and your good.

I personally use a DIY ultrasonic fogger with fan inside my greenhouse. I could run the fogger 24/7, but that isn't necessary or desired. It literally only takes 1 minute or so for the RH to reach 95%. If the fogger continued to run for 15-30 minutes then the entire greenhouse would be filled with a thick haze of fog which can cause some serious problems. That is what I meant by 'it is possible to over humidify'. Trays can become oversaturated real quick doing that.
What everyone else is saying, when having an external humidifier, you are pumping in fresh air along with high humidity into the greenhouse. In such a case you are not really ever 'over humidifying'. The RH pretty much stays level. This is where I must apologize because I did not take this fact into consideration when I spoke earlier. Sorry about that. I likely caused you concern for nothing.
Like Doc said, fanning it out at least once per day is not a chore and gives you a lot of beneficial fresh air.
There are just so many different ways to humidify a greenhouse its ridiculous. I’m considering revamping my humidification rig externally. Plenty of fresh air.

OK so I had some 2nd and 3rd flush cakes on the bottom rack... I noticed some trich one one so I trashed all the cakes, and sprayed the bottom area with a 1/10 bleach solution.. I think I have what looks to be some trich trying to form on 2 trays at the top, but I really can't tell at this point if it is trich or bruising. The trich was bright green, and very pronounced, there was no light shade of it like I am seeing on a few trays.
Am I fucked? I have two large trays of another strain that are apparently not fully colonized. First signs of trich i'm trashing them... I am transferring the questionable ones to a SGFC for now until I can be sure.
