Question about hydroton and drainage
I have been growing in coco for about 2 years. I’ve seen some people layering hydroton clay pebbles on the bottom of their pots for improved drainage. I’ve had a fungus gnat problem the past few times and I’m doing everything I can this next round to prevent them. So A, is hydroton really worth the money and does it in fact improve drainage. And B would it help with the fungus gnats at all?
