I’ve run in before, but I just made about 50 plus clones in the last month or so. I have this one strain that takes nearly 30 days to root and then some others that just take 10 days or so. i have cloned in veg and flower. I am not sure i have seen a difference in outcome.
recipe: tap water, ph to 6.0 or 5.9. 3 gallons of water. add 100 to 150 ppm of maxibloom (i used to use floranova, but it gunks up everything), shot glass of clonex solution, shot glass of peroxide. add more peroxide every 2 days. change water ever 4 days if possible. I went like 20 days without changing it and just adding peroxide and topping off wiht ph’d water, when I changed it a few days later i got pythium on the roots of the older cutting that hadn’t rooted. of all the cuttings, just three were lost.
