I'm interested to see how the tub runs go. I never could get that to work. Some things I've noticed about the bags though . . . They will self inflate (so to speak) when they get ready to go from pinning to fruiting. That's the Co2. A fan is absolutely essential. The bags will air all the way up, like a balloon and growth seems to slow down. I realized I had my fan on low so I switched it to high last night. This morning I had a fruit the size of my pinky finger. So that extra air movement is necessary. The one bag that isn't sealed is growing slow but steady. I'm worried about the RH with it. I'll pull the bags down again tonight and get ya'll some more pics.
