LST method, topping and switching to flower!

Looks good... top to fill space. need more vertical shoots in that locale? top a growth for 2 new shoots. when you fill 1/2 your space, switch to 12-12. 1/2 of an area is 70% x70% = ~.5 so when you are 70% of length and 70% of width, expect it to fill in the rest after 12-12. doesn't list it as an autoflower, but you have to approach those a bit differently and guess when that "12-12-like" flip ocurred in the plant. you are guessing how much time you have for vege growth. ~4-5 weeks for a shorter variety is about all you get. just in case... initially the longer you let it grow the yield increases at a logrythmic rate,but will hit a ceiling... might put out more material, but more fluff at a greater proportion at that point. This is determined by light and co2, primarily. i don't know your light's coverage, but figure that's the space oyu want to fill divided by any other plants you are growing.
