Well for most people I tell them to just use Ph adjusted RO water and the rooting gel or powder.

My self I use a very week and I mean very week nutrient mix like
2.5ml of Micro, Grow, Bloom and a 2ml superthrive and 2ml B-1 it works for me just fine but I watch everything like a hawk anyway. I don't use a bubbler system my self they are just not consistent enough for me.

For bubbler type system they do need more water and the water line should be closer to the cuttings then a real Aeroponics system does. Iā??m not sure if it was yours I saw but someone use what looked like foam rubber as plugs it was yellow foam like out of a mattress or something like that. Those would not work because they would take in water hold it in and soak the rooting clone stems and rot them before they get a chance to make it.

Another thing you need some Anti-Wilt spray of some type to keep the leaf and stem from drying out waiting for the roots to form.

Can you post a picture of your cloner system for me or give me a link where you have some pictures?

If you need plugs email me zandor at pot.com
