okay, so this unit is 1/5 of the price of a doboy and TR of Earth Angel seems to enjoy it:

Oh man we had one of these cheap guys, it lit on fire after a couple of months of continual usage. The temp controls are very volatile and the consistency of the seal is poor form end to end...for a hand full of bags it will work fine but for a large production system its useless. We went to the Syntegon (formerly Bosche) Doboy 750 and a 550 for the sub lab. They aren't cheap but they are bullet proof so keep your ebay eyes peeled...let me look up some other options that have been know to work well...

I would stick with a 4x8 or even a 2x8. The key is the length of thermal air exchange and the actual thickness. Let me dig up Brad original document on the design and ill post it here shortly for you. I believe there might be a thermal calculation on there! 

Hell yea! So glad it gave you the info you were looking for! We are stoked to continue going down the genomic rabbit hole with these odd stromatic proliferations!

Nebrodini are quite an interesting one, they are only really found in lime quarry’s so you need to increase your pH to between 8 and 11 for success in fruiting those buggers!

So two things cause this, co2 and too much air flow. That yellowing is due to the lions drying out which can be made worse by the porous growth of lions in too high of a co2 environment where Swiss cheese like pockets form as opposed to a healthy looking fruit…so increase the CFMs of your exhaust (making sure your intake is low in co2 first) and this, with a co2 meter controller) should limit constant air flow which will cause drying of lions and increase what I call the ebb and flow system where fresh air is brought in as dirty co2 rich air is carried out in less frequent and quicker pulses. This also helps keep your humidity up in the winter time without taxing your humidification system. 

So every other sheet of corroplast goes straight from the top of the stack (return air) to the bottom of the stack for spore and co2 rich air dispersal…let’s call these the odd sheets…the even sheets have a blocker in them at the bottom and top of the stack and a shorter piece of Coroplast. Where air comes in from the side slots and up to the duct that feeds into the plenum or fruitroom. Because of the proximity to the intake and exhaust at the bottom of the stack of sheets it’s important to support the HRV up on a short wall of brick or cinder blocks of some kind with a pit of gravel (French drain) below. This way the intake (even) and the exhaust (odd) due to their necessary proximity, don’t intermingle. Does that make sense? Hard to out into words but I can certainly make a drawing…

We are currently using XLS-As that are essentially self supporting trays, I’ll make a post on here next week to show the converted slant shelf carts we made for cordy cultivation. Trays can help but if the bags on the shelves are left undisturbed through the dark colonization and light fruit formations they are unnecessary. We did just get some bins in from SacO2 which are interesting for cordy cultivation without the bag, I’ll post those up too come monday

Not currently, we are working towards more of a physical lab complex for the growing MycoWizards communities. The first one will be at the new Cap N Stem location in Lewiston Maine within a years time, acting as a launching pad and a welcome spot for any traveling MycoWizards members to work on projects, teach classes, etc!

Welcome! Whatchu got growing?!
