Awesome amount of info and thank you so much for taking the time to post it. I see now what is needed for this to work and I guess where I was having trouble was seeing past this being a one time grow. I never thought that I would need to be vegging my next batch, while my first batch was flowering. This is for personal consump so I figured I'd do a grow at a time but that would be stupid since we are talking about a lot of time.
There is no way I can implement the steps you have discussed to that level. Carbon scrubbers and all the hoses etc. Right now the best I can do is a 250 watt HPS light at the top, scrog, with the bottom 1/3 devoted to vegging on maybe a flouro grow lamp. I will need to find a low heat (cool) light with good vegging qualities. There is no way I am running two ballasts for electricity reasons. My sheriff monitors electric around here. I will seal off the top from the bottom using a polysynthetic material that will have some slack at the end for the door. I may only do one grow at a time though and do my clones in another place. I think I may just clone and veg in another location and then transfer to the fridge for flowering. I just think the veg/flower op in that small of space will be very difficult. So I need two ventilation methods, one for the bottom 1/3, and one for the top 2/3. I wil try to figure it out using one fan, but I figure I will need two. Again, I am on a budget, and I cannot spike my electricity. The 250 watt hps worries me enough. I know I sound paranoid but I assure, my sheriff is a real cannabihater. A cooling tube and all the other items suggested are simply out of the question. I do not have the money, expertise or even place to get the items needed for this. God this got complicated as hell.
Can I get away with no cooling tube?
by placing a fan at the top of the fridge, blowing air out, while pulling air in from the bottom of the chamber (remember, that is going to be sub freezing air in some cases {Garage}) Will the chamber be cool enough?
Can I run some sort of cool veg op in the lower chamber?
Can I run a fan blowing out one side of the lower chamber pulling air in from the other? Basically cross breeze to cool?
Check out my schematics when I post them and see what you think
Thanks again for all the effort and help. Sorry I do not have the expertise or budget to do this right, but as time goes on, I can implement these things.
