i use 2 gallon buckets with straight perlite i water every 4 to 5 days in veg and every 2 to 3 in flower you want the hempy to be pretty dry before watering again just watch the plants when the leaves start to droop alittle then water again .
I was wondering im starting hempy 100 percent perlite and rapid rooter plugs...when i water before the roots hit the rez, do i water around the perimeter of the rooter or the accual plug
