I found that humidity is infact the best medicine for trying to root clones. I was able to root 9/15 clones without any cloning soulution, in but 7 days. First of all, I was able to use a simple plastic container, with a top, and razored out 15 2" sized plastic pot holes, and 2 very small holes for 2 hoses that connected from a 2 slotted air-pump to 2 air rocks. I filled my small container to the very top with 3 gallons of water, adjusted to the correct pH. Second, I placed my clones about 3/4 of the way in to 15 rockwool cubes. I placed them into the very bottom of the pot's, making sure that the end of my clone was right over a hole of the pot. I then placed into the pot's small hydro rocks around the rockwool to keep it in the middle of the pot. I then placed all 15 pot's in to holes I made on the container. Third, the end of my clones were very close to the water, but not totally touching it, only getting splurted by the air bubbles that the airrocks provided. I then put a very small amount of a grow soulution into my water, and then re-checked the pH, making sure it was perfect. Fourth, the most important part, I took a small vaporizer like such:

I then took another container, this time clear, and placed it over my clones using it as a humidity dome. I then drilled a hole into the side of my clear container, allowing the other end of the hose to fit into the hole, without leaking. I then placed a couple very small air holes at the top of the container, to allow the humidity to recycle. Fifth, I took a small 40wt flourescent light, and placed it over the humidity dome. Your creation should be like such: A small container, surrounded with a lightblocking surface, filled with 3 gallons of pH perfect water, that have a small amount of grow soulution in it. I then placed onto of the container, the cover that has 15 small holes with pots in them containing my clones, growrocks, and rockwool starter cubes. I then have a small airpump blowing air into two airrocks, inside the container. Ontop of the container is another small rubbermaid container, clear, providing a dome for the clones. A vaporizor is connected by a hose to the clear humidity dome, blowing mist inside the dome. The water used for the vaporizer, has a small amount of grow nutrients that will provide the folige of my clones to get nutrients to them, keeping you from having to spray them yourself. Shining very little light, a 40wt flourescent light is outside the growdome. This worked very well for me folks. I'm guessing with rooting hormone on the clones, that you'll get roots on all of your clones. It only took 7 days to see roots! The mister fills up the dome so well, and then the air bubbles help keep sufficent air to the clones. Just a little bit of nutrients were used. This can be made easily by things just laying around the house. Obviously, thats always better then having to pay for stuff. Remember, I didn't use cloning gel for my clones, but if I wopuld have had it, I bet I would have got a 15/15 in the first week. Almost the second week, and just but like 3 have roots. I'm very happy. I just bought soime top of the line cloning gel, however, hoping that will speed up the promise to maybe 4 days!
