yeild????

also 600 watt hps has higher lumens per watt than all others so you get more bang per watt also more points of light but its cheaper to buy one 1000 watt light than two 600's you will yield more with 3 600's than two 1,000's and use less power and a lot of growers will go hps-mh-hps for flower rooms

i'd much rather have 2 600's than a 1000w. you will yield more because of a larger footcandle layout. 1000w cover roughly 25sq.ft. with optimal footcandles. 2 600's cover 32sq.ft. with optimal footcandles.

The more light I have, the more plants I want to stick under it...and you really only need so many...so I have to stick with my 400 watters... I usually get 3 oz per plant, with 4 plants under a 400w...and I feel like that is alright...yes?--no? maybe?

Out of my 4.5x4.5x7.5 tent with a 1000w Hps
i just pulled 19 ounces off 4 plants with no Co2.
I pulled more off those 4 plants than when i had 6 in there, you need to let the plants have room to grow.

Genetics plays a role as well. I've seen the bud weight vary significantly between phenotypes of the same strain subjected to the same environmental conditions. But 0.5 grams to 1 gram per watt is a typical range. The higher yields are usually realized once the best performing mother is isolated and the environmental conditions are dialed in. Doing everything right and going hydro augmented with CO2 enrichment often aid in higher harvest weights.

i'm trying to pull 1.3gpw right now off a 600w hortilux super hps bulb in a 4x8 tent. running the tent perpetual so i only have 4 plants under 1 light and 6 under the other light right now. i also have some 100w uv flood lights. they don't affect the footprint of my canopy but i guess they do throw off my gpw number then. the 4 plants i have in day 55 right now are monsters! lst's and topped. the 6 i have on the other side are a little less trained.
