I want my plants to start growing when they have roots so that I can cut down on flowering time. I run a SOG style grow, clones for me are the make and break of my schedule. You leave clones in a cloner for 3 weeks? Inefficient, by that time I am nearly halfway through flowering those same clones and producing bud. You don't know why you do or don't need a dome, so your opinion on the subject is irrelevant. Lots of methods work, nobody is denying that, and no one cares if you have 99% success rate with your clones. This is about finding out the most efficient and cost effective way of growing so that we can progress the knowledge of cannabis cultivation. Yes I use an aero cloner, bubble cloner, rockwool, 100% perlite, 50/50 perlite/vermiculte, I use all methods of cloning because I am trying to figure out the most efficient ways of getting clones.
Also you don't even understand the variables in the difference in where you live versus where he lives, what surface the container is on, the RH, or any other variable that would play a factor in why a method that gets you clones in 5 - 8 days, takes him 8 - 14 days.
