I had some good success with that bought got too anxious and messed with the plant too much and broke the stem. What sort of problems will I run into with the large rockwool cube covered in hydroton. Aside from the wool holding water longer than the hydroton. Will I be just as successful with just using the hydroton?
That depends on how large your rockwool cube is, I suppose. If you have a plant in a 6" rockwool cube you might water it once a day. A 6" netpot with hydroton you might water 4x a day.
