I am in Costa Rica scaling up to a medium size facility, and my biggest issue now is spawn. I can get access to feed grade Millet or seed grade sorghum and forage (for grass) oats. If you had to choose one which would you go with? The oats and millet are cheap, the sorghum extremely expensive 

Crystorage:

I'm in Costa Rica, and since all my genetics are imported, and importation can have a month + lead time, it's important I have all onsite storage. 

Is -80c a hard rule? My local brewery has a -20c freezer. Will that suffice? 

If it does not, does anyone have a cheaper small tabletop size -80c freezer they suggest for storing say 4 vials each of 16 strains (64 vials)?

Anyone know which impulse sealer this is. I need one of basically this size for my build out, the one Myers sells is too big 

Almost done setting up my 4 reefer container facility. The biggest sticking point is the HVAC. 

Ive received so much conflicting information. Each grow room container is roughly 26m2 (280ft2) in dimensions and 67m3 (918ft3). 

Ive talked to people who say because of evaporative cooling with the misting i can do fine with a 2ton (24k btu) split unit behind a plenum, others say i need 5 ton (60k btu) minimum. Im hoping to fit around 400, 11# blocks in each container. 

Anyone have real world experience with container growing?

Our climate is caribbean costa rica, average 23c-29c/75f-85f daily and were hoping to mantain the container at 16c-17c/62f-63f
