lol dude, if you use some black hefty bags for growbags youll be growing some fuckin legend status monster plants, lol. Fill the bitch up at least halfway with soil man, n then sinch the fuckin top up, so everything is nice n packed in. Put your seedling right in the opening, and let that fucker BEAST OUT, lol. Thats actually a fuckin sweet ass experiment to do now that i think about it. I gotta wait until this grow im doin now is done though cuz ill probably only have room to do one plant in my tent, as opposed to the 10 im growin now, lolol. There is so much potential in growing a plant in a trash bag or in a 20 gallon rubbermaid tub with soil man. HUGE potential, lol. youll be lookin a little closer to an outdoor type of yield if you let her veg for a nice long 8 weeks, and then pull her trigger. N top her like 3 times, lol. Youll have a LEGEND plant man. just make sure your using some good genetics, just to top it all off.
If your just lookin for convenience rather than growing out one massive plant, its like 30 cents a bag, if you buy 10 3-5 gallon growbags itll only cost you like 3 bucks, so for multiple plants the growbags are the way to go. iF your lookin for one monster, then use a trashbag and messege my ass with the link, lol. If you got room for multiple trashbags, MESSEGE ME WITH THE LINK
--lol, sorry man, ive seen it done once and just lookin at the plant got my fuckin rocks off, hehe.
