I made the jump into Coco too... all my seedlings, veg, and some of my flowering plants are in it. Even the stuff I started in soil? Fuck it. Coco. Tons of reasons. 1) Mites in soil. )(*&(*%$. 2) More control over nutrient and ph working with a relatively neutral medium. 3) It's prettier and doesn't make the mess that soil does. 4) Easier to store. 5) I can auto water the shit. (OMFG WOOOT!) 6) Goes to #1... it's a lot easier to maintain a 30 gal res than mixing by the freaking GALLON 20 million times a week. I miss hydro. But my current spaces aren't really good for the type of system I used to run. Did a lot of research and looked at a lot of peoples' work in coco before I made the jump. Oh 7) EJ Seablast is good in coco too. I don't have to switch nutes. The list is long regarding why the jump worked for me. Run a couple of plants out in it and see how you like it. OD mentioned something about Cal/Mag. Got a gallon in yesterday. Even if the coco you buy claims it has cal/mag supplement in it, run the normal Cal/Mag through your stuff. I went light on 1 feeding. Heh. Not again. With soil you are be marginal somewhat with your nutes. Like if you screw up something by 1/4 tsp, it's probably already in the dirt depending on how far along you are. Coco? Nothing is there nutritionally for the plants. So there is that. But that's the only thing I've found so far that's touchy.
