My neighbor has two with tomatoes growing in them. As they are getting quite bigger they are all bending up towards the light, which to me sounded kind of stupid to grow upside down when in reality they grow up towards the light! :wtf: But come to find it, it works well with tomatoes as to when they fruit the tomatoes weigh down the branches causing them to straighten back down. As for cannabis, it may work (not likely) but you would probably have more problems than anything. Especially like with mentioned above about the runoff. Plus if you do try the lighting from underneath you would think to remember that the run off when watered will get all over your plants AND
be a serious hazard for the lighting underneath. I'd advise stick to what's now not what could be. If you already have some you bought and didn't like it just use them to hold your buds branches when drying as that is all they are good for!

People buy into it because the words topsy turvey upside down thing-ama-jig in a tube. That growing idea is just as crazy sounding as the Wacky Waving Inflatable Arm Flailing Tube Man from Family Guy. Maybe the same people made it!

Italiano715 Reviewed by Italiano715 on . UpsideDown Theory So i see this commercial on TV for this Topsy turvy tomato plant thing that basicly grows a tomato plant upside down. of course my first thought is will this work on cannabis? if all your lighting is on the ground facing up i dont see why it wouldnt. it keeps the soil in a bag/basket kinda thing and u water it fromt he top, and its all suspended on a hook. so if you have 2 rooms, 1 with all your lights (light room), and one with no lights (dark room), and youve got enough lighting for lets Rating: 5
