2gallon Clay Pebble vs 8inch Rockwool

24 floraflex potpro platforms - top feed drip rings

Does either one have an advantage (growth/water usage/fill and disposal)?

How many times a day would you need to feed 8inch Rockwool cubes? Volume is 8liter = shot size 3% = 240ml - shot size 6% = 480ml

Rockwool blocks generally need watering once a day in the Vegetative Growth Stage and twice a Day in the Bloom Stage.

rockwoool can get nasty.

Hydroton is completely inert and can be washed and re used indefinately. Hydroton in a drip system can be feed 24/7 but I recommend not more than once per hour of light time systems I am familar with drip until ebb then off for the rest of the hour. Wash the hydroton several times until you get no clay run off then you are good to go.

Love pebbles. Love. Though hydroton is a little irregular. I like the rounder ones. They riddle better, and if flooded deep, they can be stirred. Not that you want to stir them, but it's easy to plant into them, if they are cleaned and soaked actually in the system. Root in an aero cloner and you have a very sustainable system.


Rockwool.. never again. I spent years getting away from it. It's a health and safety risk to you, that you rarely hear about, and then the environment. It's not good to grow in either. It's old fashioned.

I'm going with Rockwool cause it's easier to store everything in my one bedroom. 50l bag of clay pebbles weighs 50lbs and I would need 4 bags every grow. Then it takes up space filling the pots. Rockwool might use less water also.

I set up a system I can easily switch back to clay pebbles next grow if this doesn't go well.

Are you listening.
You don't chuck pebbles away each crop. That would be insane.
One of the best things is that you don't fetch anything each crop.

Skunk it's time to get those seeds cracked and growing! Keep us posted on your results and remember learning how to not do something is just as important as learning how to do it, either way, we learn from experience. Happy Gardening Friend.

It doesn’t take much of the rocks. I’ve gotten 8 zips off an Afghan in a half full gallon container. Normally I use the 5.5x5.5 containers and get 2-3 zips per if I’m not doing sog. I’m pretty sure you could get a full lb off one plant in a 5.5x5.5 if you trained it right.

In my experience flooding the table very often for the shortest time to get it full works best.
