you can go with 2 or 3 gallon buckets. BUt you will have to keep a close eye on it, because your pH could blow up really fast since their isnt too much water to balance everything out. The grow sight is probably in our house so you have the conveinience to checking up on it whenever you want. Plus if you only have 4 feet to grow with the smaller buckets would be perfect to control the heighth.
Jared530 Reviewed by Jared530 on . queshtion on bucket size for DWC Hi ive been growing in soil for quit some time now. but want to try out hydro =) my set up will be a 30 gal res. with 9 carboys. "1 is a control bucket" my only prob is hight being an issue. i got a 4 foot tall flower room. and about 3.5 foot tall at the bottom of the light with it all the way up. so my queshtion is. instead of useing normal 5 gal carboys. could i get away with a 2 or 3 gal? same diamiter and everything just shorter. i know it will be more maintnence. but thats ok i can deal Rating: 5
