Are they flexible? I've used to small square rockwool kind and they weren't, and I've used to big deeper 12" or whatever topper kind that were. The non flexible kind were a pain to get back off and would eventually cut into the stalk. I disliked both because I scrog and the stalks sometimes grow at an angle, causing the topper to become uneven and making it pointless aside from a light shield.The FloraFlex matrix discs are fantastic. I grow in coco and have been using coco/perlite. They do a bunch of things. I hand feed. They help evenly distribute your feed. They block light from the top of pots so any perlite on top won't grow algae. And this size matrix disc fits exactly inside my 3 gallon Vivosun cloth pots.
My last plants I ran I finished in 1 gallon cloth pots. Wasn't the plan just happened that way. One was a coco/perlite mix and one was just coco. They both turned out great and won't be using perlite any more. Just no need for it, IMO.
