...Actually, I did run a few 10's last year, and they are about the limit I care to move about...especially after watering...I didn't see much difference size wise between them and the 7's...could have been the strains tho'...this year I thought I give the bigger pot thought a try, and they are bigger...however, like you, I like the option of moving them outside to work on them and water/feed(keeps the room so much cleaner) and photo op's...it's that reason I may rethink my plan for next spring...I was gonna run six 15's...three Docs "kit" and three using my soil mix...now I'm not so sure I want the girlz housebound for the whole grow...got lot's of time to figger' out my final plan to'...
These are the ones I use,(made by Hydrofarm, found on the Zon) and they are the same material, just different dimensions...even the 15's are sturdy enuff' to lift if Ya' have the back to do it...the reinforcing for the handles seems to hold up and they're big enough you could use a XL tomato cage or even fab up a scrog set up if you don't mind stationary...
I've also got these ones, which seem to be equally sturdy and a good deal for a pack of 5...and of course I would be remiss if I didn't say to check out our
sponsors and look at their offerings...
...anyways...cheerz...h00k...
