Has anyone ever used growstones in a hempy bucket? I might switch from dwc to HB but dont like the idea of having to wash all that perlite? I have also heard of people using other mediums aside from perlite and vermlite. Anyone have any input about using other mediums. (Kitty litter, oil spill absorbent, lava rocks)
oil absorbent gets your plants silica in case you dont already supplement potassium silicate. lava rocks have iron and are cheap if you find the right spot, the guys will usually sell 5 gallon buckets for $3-5...
I actually have a 2 liter hempy sog going right now, mostly perlite/verm mix but one is growstones and vermiculite. About halfway through flowering and it looks the same as all the rest. You definitely need the verm, don't think just the stones would do a good job at wicking the moisture upwards. The one downside is its heavier so hard to gauge when to water.
I also have a 2 liter Hempy sog going right now. Half with 100% Perlite and Half with Perlite, Vermiculite mix and watering the Mix every other day vs the 100% every day to see if it actually makes any difference. I recently saw the Growstones and thought I would try them out, but now with Cannabull's feedback, I may hold off.. I also hate rinsing the Perlite, but only cause I have not devised my way to make it easier yet,, Im getting there!!
Im subed to this thread. I was going to try a perlite only hempy for my next grow. Then I saw the grow stones and thought id try that instead. After finding this I think I will go with 100% perlite hempy. Sent from my GT-S5830 using GC Forum
