@Mike--How long did it take to put mine together? About a day once I had all the pieces and parts. I really have too many spray heads but that's a good thing--just hard to keep the thing from leaking b/c my pump is pretty strong and large--but adjustable. As for grow light, you really don't need much. I use a mixture of T-5s and some others my friends gave me. The lights are free when you buy a lamp. I have 4 sets of lights. Two 4 footers and two 2 footers -- Three have 4 sets of lights. ALl of these are plugged into a multi-switch that controls the pumps and the lights. Once side controls the lights, the other side controls the pumps--all on one switch.
July was a crazy month for me and I had to work some long nights and a few weekends. So, some cuttings actually stayed in the cloner for 30 days. As long as they had water, food and light, they were fine. I have....
1 - EZ CLoner 32
1 - EZ Cloner 64
1 - Commando XL 35 Cloner that I built (leaks a little no matter how much foam tape I put with clamps!)
1 - EZ Cloner 128
What is my success rate? It was 86% until I tested a set of cuttings in the bucket system. Every cutting in the bucket cloner died---the water was just too hot. However, let me mention this too....some cuttings are just not good cuttings. It may look like a good and strong cutting but if left on the tree may have died anyway due simpily because of nature. So, success facts can be misleading no matter what method you try. As for water pumps, some folks say to run the timer 15mins on and 15mins off. I don't do that. I just let the dare thing run! The fastest cuttings that root are the freshest. For me, it was 17 days. What cutting was it? Dominck's Black cuttings....all 8 or 10 of mine rooted. Started in June, some are now 18" tall of new growth. But again, all cuttings are not equal! Remember that! However, I won't be going back to rooting cuttings in moss or dirt again. I use to root inside my office and my basement. I had to find a way to root without all the mess and to get rid of gnats. The cloner seems to be the best method for me. My ultimate plan was to use my greenhouse for all my cloners but I have not perfected the controlling of temperatures inside there. But I will say this, for about 2 years I kept buying Nero 600m cuttings from VS and every one died on me using a variety of methods. Using the cloner for the first time with moldy cuttings worked for me! I think the natural air, heat, and warm water had something to do with that....kinda like sticking a cutting in the ground and letting mother nature do the rest. Well...sorta!
Good luck guys and have fun!
