So, ive got about a 5x4 space. with a 400w MH
Lights are at 18/6
Temp when on:75
Temp when off:60
RH: 40-60

I am useing the full FoxFarm nutrient setup every other watering, started in jiffy pots, put those in the foxfarm potting soil. Growth of about 1-2cm outwards and .5cm upwards a day. 4 Sour Diesel, 2 CHeese, 2 Pineapple kush, 2 BLue Goo, 6 Mystery seeds from trimming at my friends farm last season.

First of all, do you guys think that light is powerful enough? i havnt figured out which ones are male/female yet. too soon, when i do im guessing that will go from 16 plants to about 8-10 (if im lucky)

My ballast only supports 400w and i dont want to spend the money for a new one unless i really have to... ive put almost 700$ into this. dont want to reach 1000 lol.Attachment 913647Attachment 913649Attachment 913650
So thats my setup, im hoping the reflectors can make up for the extra 6" i need on each side. every single plant has amazing growth. only a few of the sour d's are sensitive to the fertilizers. got a tiny bit of spotting on the leaves, the rest are just basking in the guano and earthworm castings from the nutes.

Mid summer, the weather where i am will let me take them outside for the end of the flowering.

Anyone have any suggestions?

Or any strong opinions on my lighting setup?
