They aren't children, so I don't lament the loss of a few of them. Some are just destined to not suk water up the stalk, it would seem. I've got the process down to where I can do about 50 or 60 clones an hour, when the market demands them & I have the vegged out product to do it. The tent I mentioned holds about 100 easily. Right now I'm using these cheap Planter's Pride self watering trays that hold 28 clones each. I put the peat pellets in the 6 cm pots that go in holes in the tray. Peat pellets can dry out on ya in a hurry if ya don't pay attention, so these are handy as long as you don't over water. Peat needs to be moist but not wet to promote vigorous root growth. Once they go in you never have to touch them. & as I said no need to spray the leaves, which delays rooting, since the humidity of the tent is adequate for the clones to survive. Thanks for the tip about Roots Excell, maiden. I just picked up a 48 ounce bottle of Miracle grow transplant & root promoting juice for 7 bucks. Since Olivia's is about the same price as gold per ounce, I'm gonna do the next few waves without it & save. I did use this once b4 many moons ago, to clone a bunch of Norhthern Lights for a farmer friend & if my memory recollects, the results were fantastic, as far as quick rooting & survival rates.
