I
still just don't understand the appeal of the tent, lol...
I do understand the appeal as Old Salt so ably detailed but I fear all the equipment people are buying to grow may deter new growers or convince people they need much more than they do.
I grow in my basement and by keeping the environment to my liking it is happily good for my plants too and sure if I strictly controlled the environment I could likely get more yield but since I am growing several-fold more than I need I see no point in such a big expenditure. Also, the smell doesn't bother me at all and isn't that bad outside the basement. People who visit say upstairs say they can't smell it.
But the biggest reasons besides what I see as a lot of extra unnecessary cost is that I could not imagine the hassle they are with cleaning them and especially trying to water and trim and such in such a small confined space. When I do anything like that I can just move my reflectors and I have tons of space and have total access. To each their own!!
