My box is 1m x 1m x 2m. I was planing to put 5-10 pots in box in leave then to grow for about 1m and then switch to 12/12. Is that true if i top the plants for once time there will not be nice sticks sorrounded with hemp? I heard that if you top plants there will be two tops(i knew that) bit willbe hemp just on the top, not on the whole "stick". How much litres should the pots be to let flowers grow to about 1.80m? I think that 5 pots of soil will be enough for m2 place of 1.80m heigh plants? So should i use topping technique(for just once) of leave them to grow with no technique?
