so i topped my 1st plant let it grow up a little and then fimmed it. now i have 4 more main stems coming off the top of the plant. can i repeat the process to the new stems?
some strains take to it more than others but you can definitely top/fim multiple times. you'll just have to factor in some extra veg time while the plants recovers.
Some one did a test on this hear to see how many times he could top a plant succesfully. Im not quit sure where it is but im sure if you look.....you will find it!
Consider that topping and fimming are no different in nature than taking clones and there are ppl who have been taking clones of the same mother for over 2yrs, I'd say you can top till your hearts content and she will keep recovering and growing more tops.
