I hate to burst your bubble but without more light you won't get anything near AB or Mine. You can get some decent small buds with that much wattage but yields and plant size will be on a much smaller scale.
Shit. I didn't think about the width of the plant. Well I guess I'll just have to get creative with the LST'ing. Looks like it will be a one plant flower chamber. Cuttings and small seedlings can share in the other two.
