I use promix which is "technically" soilless so it can be used as a hydro medium "technically" *finger quotes* hahaha
Ive been wanting to switch to coco cause a friend uses it and says he gets some faster and bigger growth out of it and if you have a nice mix of pith and fibers it holds a good amount of water. But no luck this go around. Couldnt afford to fuck up these mommas. Once i get the first round of clones though i might put 1 of each in coco and 1 of each in perlite and do a side by side test taking into account ease of feeding, nute issues, fixing those issues, amount of watering vs the added growth that is obtained.
What you guys run in?? I know most of you are hydro of some sort
