That's what I've been using, Clonex into Root Riots and I have had a very high success rate. I'll try doing a couple into the cubes without the gel and see if there is any difference next time I'm cloning.
I used it my last two grows with some success. I used the Bloom heavily during flower and got some nice flowers. I found Grow to be quite potent, it burned a bunch of my Blue Dreams and Blueberry but the more hungry strains didn't burn. I use it sparingly now when I set up my final pots.
I have a friend and all he uses is Clonex, then straight into soil. He swears by it, but I had very limited success using his method and went back to cubes.
I use a lot myself, and I'm not self conscious about it anymore. When I switched to cannabis for pain I felt judged at first, mostly because I medicate as soon as I wake up and take edibles to get me through the night. I am medicated constantly. It wasn't until my wife pointed out that I was on...
I've foliar fed Extreme Serene to vegging plants before. Harvest was larger, but that also may have been due to more experience from my first couple of grows.
