can you fit a 20gal tote (storage bin)
There could be some problems with the rooting systems. I'm sure if you train them correctly (LST), you can get more production from the 4 plants than you would have off of just 1 big one grown to its full potential (that is just my opinion though). I usually use about 15 gallon/plant separated outdoor to get each plant to their full potential. You probably won't be able to get all 4 plants to their full potential, but it should work. The biggest problem you will probably run into is space for light of course, that's why it'll be important to train each plant well. Good luck. Post some pics if you get a chance to show what it actualy looks like.
Here it is the one growing out on my balcony, the one in the back suffered a bad case of heat stress then my outdoor environment is pretty hot as well, was a bad day for em all, just the on in the back is taking a little longer to recover, as I needed to put them away in a Crawl space one day with a 20W CFL, but its slowly recovering.
The two on the left are 4 weeks in the other two no the right are just under 2 weeks
