I use a 6 gal. Space Saver by Air Care. It does well in a 4x8 tent. Not sure how well it would work in a large shop. I only run it on low though so it might work for you on high. I'd look for a portable swamp cooler for a shop.
Hey, I was looking at your Photo, Mars, Soil grow from some time ago. I noticed a humidifier in the pictures. Can you tell me the make and model of it? Also, did you have air exchange in/out of the tent.
The reason I ask is because I am struggling to keep RH up. None of the humidifiers I have are doing the trick. I do pump the minimum amount of air out of the tent necessary. Everyone keeps telling me to fix the RH in the room I have the tents in. Well, its a giant shop. So, that is kind of hard. Just wondering how you did it. Thanks.
I really enjoyed your post about weighing seedling soil in solos ... I did exactly that, I weighed the cup before planting and then after watering initially.
Questions if you dont mind:
Do you recommend watering when the cup returns to its "soil just taken out of the bag" weight? Or just near? I pushed a seedling to wilting just to see and the soil in the cup was still dark, so I'm trying to understand what the "dry state" of the soil thats ready for watering really looks/feels like.
Secondly, if I may be so bold, do you have a process for how much increase in fluids per plant height over time? You mentioned a shot glass every 3 days. Im assuming this is about 1.5 fluid ozs, do you up that by .5 oz per 3 days as the plant grows? Something like that?
Buds - wondering about the best time to move some autos out of doors in AZ. I'm thinking around the beginning of February? I assume by May/June things are getting too damned hot... I am also assuming that only autos are possible out doors here due to the heat?
