That is exactly how i read it on the web somewhere, and i love you getting 80% rooting after the exercise.
That is how i am gonna do it, while the new seedlings take off, i will have the clones of the current genetics in hand to try and make them grow the most uniformly possible, gonna be doing Cinderella 99 by @Baudelaire and also Hiro by @Swampthing as soon as i move.
I might need two 4x4s, to have all the genetics running in veg, after that i am gonna choose the best three females of each and take them to harvest. 12 plants exactly like last time, but the topping will be done twice instead of once this time around.
