and as far as air pruning goes.... i just pulled two root balls out of my pots, and where there are holes in the sides, the roots are only about 1/4 of an inch back in the soil, but seemed clustered around the holes back away from the light just barely into the soil,
it lookes to me like...
Nizmo's right didnt say anything about air pruning. i think the number of holes i drilled in the pot let the soil dry out at a good rate . i think thats a big help because i fertilize every time i water.. i think the more regular you can get a feeding program the better it is for the plant...
iv been growing for about 6 years, mainly outdoors till the last 2 years... Nothings better for your plants than the sun, but ill trade that off for dual spectrum indoors. works almost as good... and thanks for the compliments...
lol thats not wet weight, who weights there stuff when its wet? if you cant tell they are in five gallon buckets... they are... cover and entire 3 x 3 area, perfectly flat, and they only veg for 1 month,,,
use some compact fl. lights but alternate bulb spectrum, you can find bulbs at 2600 K or so, and also some at 4000 K, just use a couple of 26 W's and it would be better than those incandescents.
Ya got to stretch mylar tight on a flat surface to utilize it to its full potential. i used a light meter to see how much of a difference there was, and it was about 30% more with it tight compared to just hung loose.
