You may want to google homegrownhydroponics in Tempe or Glendale. The have the rabid rooters plugs and clonex. You can also go to Walmart for an $8 digital temp/humidity meter that can go right into your clone dome. Spray the dome and NOT the plants. You never want the clonies to be wet and drippy, that along with high temps will rot them badly. When you spray let them get fresh air first for 15 min or until they just start to wilt. I give the plugs a single spray each every couple days when the humidity gets hard to keep up around 70%-80%. Sounds like if you have no clone dome you're around 40% humidity, not good for those drying out leaf tips. While at Walmart get a tall cake dish, throw the surgary mess excuse of a cake in the trash and use the dish and clear lid as a your new clone dome. You'll need a good quality spray bottle that can spray nice a fine.

I don't know what else, Godspeed.
