Ran across a thread that intrigued me. Long story short it was about raising co2 levels for outdoor plants without keeping them in a greenhouse and a few people use the cal carb.
Is suppose to add co2 along with having calcium in it.
I read lots of reviews as well as watched a video. Supposidy the calcium will actually leave a powdery residue on the leaf surface that will raise the PH of the leaf making thr plany more resiliant against PM.
I know their other products are amazing, just wondering has anyone used it and what are your thoughts?
