I prefer to use 'dip n grow' because you can decide how strong/diluted the solution is. I usually use the "5X" most concentrated mix. Plus it's super cheap. I've also used Vita Grow with great results. When you root in soil-less, there's no stress/wilting when you transplant into a larger container of soil. You have a fully rooted clone in rockwool or rapid rooter....you can bet your ass it will stress and wilt when transplanting into soil. That's why Sub always puts a baggy over the 1 gallon pots when transplanting.
