Hello everyone.
Not a forum guy, but read so much info here that wanted to make a post as a way of thanking all and hopefully helping those starting out if all goes out well.
Quick background info, not an engineer just tinker, shitty country with just basic supplies. Surprisingly managed to find the same GH everyone seems to have. Only tried once hidro juana, 1 AK47 150 grams yield, too messy and high mantainance for me, cooler catched fire. Was afraid of growing assassin shrooms but was happy to see how "simple" and low mantainance it was. I don´t have much available time so i decided to try out something that could be kept as much automatized as posible, figured GH would be the best choice given how low temps i have here on winter.
So here it goes!! Feel free to trash it, first time grow. Starting from the bottom-up:

- Expanded polyurethane mat to keep heat (floor is fucking cold), couldn´t find a normal plastic tray bigger than the gh size.
- Two reptile terrarium heating mats (dialed at max 28-30 ºC). They keep the first tier around 24/25 ºC and the GH overall at upper tiers at 22/23 ºC. Not an efficient heating method, but low electricity consumption and low fire hazard risk.
- Perlite tray to help w/humidity retention (also dry as fuck climate).
- First 4" hose on the side of the GH connected to two 4" coolers w/dimer to help with FAE. Probably wont be neccesary and opening bottom tier zips will be OK, had them in the house so it didn´t hurt either
- Second 4" hose comes from the ultrasonic humidifier at minimum potency. Tried and best position i guess is on top, it has certain air pressure but this way gravity does the work carrying cooler mist down and condensation over the device is avoided. Tried inside and the device malcfunctions. For now no static pressure problems. The hose inside GH roof is punctured to allow even distribution of the mist. Almost no mist reaches the upper tier so there should be little concern for too much condensation.
- Shitty higrometer and several thermometers to try and get a feeling of the environment, will be leaving just the shitty higro/thermometer once done. Would love to go full Inkbird, impossible to get them here.
- 4 blue led lights, 460nm, w/timer and potency dialer. Had it in the house, i don´t now if it will be useful being near a window. Very little light levels here-
- Ozone machine nearby runs 1h per day when im away to keep contams at bay. Had it before, barely noticable, hope it doesn´t affect shrooms.
First parameters:
- Cooler runs 2 mins every few hours
- Humidifier runs 15min every 1.3 hours.
- Timers are pure shit with limited config so cant runn 1min on 5 off for example.
Obviously will be tweaking this setup once GH is full of colonized substrate. By now RH oscilates 90%-100+%, temps 21-24/25 ºC, no heavy condensation on the GH cover.
I am using whole Oat grains and BR and Coco+gypsum for the substrate. PC reaches 10psi only so guess i have been lucky with inoculation.
Pics are colonized jars of 4/5 days ago. B+ and GT.


For the sake of seeing the mist, mixed of blue/red lights used.

Will keep updating on the progress.
