If i had the rooms i wouldnt worry about tents tailor the rooms to your grows needs. Like others said do some research and find out what equipment suits your needs best. And another thing is you may wanna start.
Yeah but unless your just going to panda film the room or paint it a tent is a lot cheaper normally than setting up a room and harder to take away
plus you can replace the tent after you have to get rid of it fast once the cops smash up your grow room you have to rebuild it all
@OP where you from bud ? would need a lot more info
basically you need air in and out with filters, lights and something to grow the plants in, as well as electricity and timers, you`ll want to store and filter your water also make up your mind if you want to go soil, coco or a hydro set up, hydro can be a pain but then you have no dirt to deal with water go`s down the drain
another thing to consider is if you want to use seeds every time or grow some mums and clone them
there`s a lot to take in and none of us know how much you know
Really dude your asking a lot
just give me them 2 rooms and I`ll give you 7K in a few months and some bud to enjoy, lol
