There are 2 types most people will make them selfâ??s. One is just a bubbler and uses aquarium air stones and air pump. The idea is for the bubbles to rise and pop raising the humidity and feeding the stems that hang above the water when the bubbles reach the top and they do.

The second one is a little more detailed but has a greater success rate over all. It's a true Aeroponics sprinkler system. You build a sprinkler system out of PVC pipe and use a power head and drip sprinklers to spray the underside of the lid with water (you drill out the inside of the drip sprinkler you do not want a limiter.). You do need to seal the tank to keep it from leaking. It's harder to build a good one. If you do it does work better then anything else. You do feed them with a very week nutrient mix I use the GH 3 part w/B-1 and have great success like 98.5% from the last 500 clones I took to give out this year alone. Only 70 at a time but I keep them going year round.

Light for clones I prefer fluorescents. The like the 125w Cool bulbs (6500k) with just a bat wing and Mylar on the walls. The Lights of America 65w security light they sell at HD works well too. You just get more light with the 125w bulb from the hydro store.
