yea i can only lift that 1000w so high and there gona blow up flowering ya know same with your 600. gona be dank ass indoor when all the girls are done, im topping them every 3 days cause they grow out, so 1 or 2 more toppings in b4 the 1st. they should be 24 -26 inches wide basically a square bush almost hahahMy tallest is 17 inches, I don't think it's going to get much taller, I'll probably need to transplant it one last time before flowering her. I don't want them getting too tall either
