Hello! First time grower. I have my clones in rock wool trays of 50. One tray is having much more success than the other, which has experienced a lot of failure. I’ve been misting twice a day, and allowing them to breathe for 20 min each time. Now that they are rooting, should I transplant them into the 3x3 cubes? Allow them room to grow on their own? All advice is welcomed.
