I made the same bubbler for clones. So :
enough pression with an air stone to wet the lid, so the roots with the bubbles, the cubes must not touch the water.
i put an EC of 0.6 so 300 ppm.
air 24/7
and it works!!
When the roots are 5 cm, it's better to separate them before hurting the roots.

fhydro Reviewed by fhydro on . Help with bubble cloner I just built a bubble cloner out of an air pump, small rubbermaid container...... and need some help with running it. 1. How much air pressure should I run through the 2-10" bubble wands. 2. What should I set the water level to. 3. Do I run the pump 24/7 or have it cycle on a timer? The cloner is made out of a 6qt rubber maid contain, it is pretty small. About 13" Long, 8" Wide & 7" Deep. Any help would be appricated. Rating: 5
