hey brother...
you had PM'd me and i wanted to just post what i felt here...as others had touched on what i wanted to tell you.
you asked in detail about running sealed rooms, with details of setup and design. i REALLY appreciate the in depth reply.
my suggestion PER YOUR DETAILS, that your friend and you need to start simple.
do not try for "the most optimal conditions" as per your msg, but just start with tents like you wanted to do originally and focus on pinpointing "how to's" with them.
as air flow, humidity and lighting conditions as well as you manipulation of soil bases and amdements considering you wanted to do soil.
i prefer hydro, but you never having completed any indoor grows i stil stay firm at stayng simple and going from there.
there are alot of member here with great advise and you are wise for pming ppl and trying to find the best bet.
but in all honest opinion i think to start with a few bigger tents with 1ks and go from there after really nailing the conditions.
you guys have the right idea with the sealed rooms but getting it dialed before really "committing" is best.... better to set many eggs around than all in one basket.
