The downsides to such big pots are:
1. You have to be able to buy and then throw all that soil away.
2. Moving the "pots" around is a b*tch.
3. I didn't see a huge increase in yield.

So, for me and my 9gal waste cans as pots...not again....I'm going back to smaller pots....prolly 2 gallon if that.
ProGroWannabe Reviewed by ProGroWannabe on . 20 GAL POT??? Can you grow a plant in a 20 gallon pot? I just purchased 5 big ol pots that I will (you know!). Just wanted to know if it was possibile.I have 2x1000 watt lamps as well.So light shouldn't be an issue with the pot size. Thanks for any suggestions:hippy: Rating: 5
