I got 10RS, 9grassroots, and 20 sips.....I like them bags too...but theses grassroots are cheap and nice....they don't run right out the side....also my hydro store carries all sizes....I think I'm going 7gal next since I'm orgy potting....2 to a pot in my veg tent.....2 to each 5gal rs bag.....9 bag 18 plants....I had more but I pulled them out....only 2 to a pot.....some in my flower tent have 5 or 6....and it makes plants to small....but 2 in 5gal is perfect actually 7gal would be......I'm just going to keep switching......
