Trying to get max yeald and quality

hi im a new grower and have a few ? i have about 20 plants ina 5x41/2 foot space and im useing a mix of t12 bars and cfls to veg but im gona use a 400 hps and a 400 mh to flower will this be enough light or should i alsokeep the florecenc to ? any help would be great thanks oh by the way its all afgani if that makes a diffrence or not or if they need specific amounts of light for good quality yeald thax

keep the floros on the sides if you want but only use the HPS during flowering.. MH is for veggin. if you have two ballasts just get a conversion bulb for your MH.

The more light the better!!! I have roughly the same same area with a 1000watt=) so IMO if you have two 400w ballast run both the MH and HPS during flowering if you only have one ballast.. MH --veg and HPS for flower

how often should i nut them they are in 1 1/2 foot tall 1foo 2 in across pots and the are decently bushy 1' to 1 1/2' tall and im gona run both ballast to see if there is anyy truth to this uv light thing ive been reading about

Ive read ever other water but I know caligrown uses nutes for every watering and several others do as well.. I'm going to try use nutes every watering myself.. watch your plants they'll tell you if there unhappy or not=)

I use nutes every third watering. If you use it every watering then you will most likely need to flush them about every three weeks to keep salt buildup to a minimum.

how tall should i veg them before i start budding
