A quick note, and this is hardly scientific, I just thought you might find it interesting UB. I recently started my first indoor grow. My seedlings were started in 16 oz solo cups and after a week I transplanted three of the quickest starters into 1 gallon pots. Bear in mind that as a new grower, I was searching the net everywhere trying to figure out what I needed to have on hand to grow weed, and I bit on buying a 4 oz bottle of superthrive. When I transplanted the three seedlings, I used it at 1/4 teaspoon per gallon. All three plants were doing well and I wanted to use your topping for 4 main cola method, and use the tops to make clones since I was using old bag seed and germination went poorly(about 33% success), and I was out of seeds. My most vigorous growing plant was ready to top and my order of clonex had not arrived yet, so I figured I would try to clone without it. I used 1/4 teaspoon superthrive per gallon of water as basically a guess that it might help with cloning, to water it in, and put the clone under my light. A few days later, my clonex arrived and I used it to clone the next two plants that I topped. I did not use superthrive, as I read in another one of your threads to use it for transplanting only after I had used it on the first clone. Well, much to my surprise, two weeks later, both of the clones I used clonex on were dead, and the one I used ST on was alive, and rooted surviving on it's roots. I am not claiming ST is a good product or anything like that. Just stating what happened.
There is no doubt that I did not clone correctly. I didn't even use a humidity dome, in my inexperience. I probably over misted them too, keeping them far too wet. That may account for the two with clonex dying, but they all got the exact same treatment after cloning. It's a head scratcher to me, but I think next time I clone, I'm going to do a comparison and see if I can get some value out of the 9 bucks I spent on Superthrive. I'll let you know how it turns out.
UB, thanks for all your no-nonsense gardening knowledge and being willing to share it with us noobs. Without your threads, I would have been another victim of the snake oil salesman.
