    I am about to start a 60 plant scrog. The plants will be grown in 3 gallon buckets. I can fit 16 buckets in a 4X4 square. In your guys experienced opinions, How many of these plants can I veg under one 1000 watt metal halide, and how many can I flower under one 1000 watt HPS.

    So you are saying that one 1000W HPS light will cover a 4x4 area? (just asking because I wanted to know the area a 600W HPS light would cover)

    From another post on this site:

    • A 250 watt fixture will supply enough light to cover a 2.5 foot by 2.5 foot grow area. (6 plants or less)
    • A 400 watt fixture will supply enough light to cover a 4 foot by 4 foot grow area. (12 plants or less)
    • A 600 watt fixture will supply enough light to cover a 5 foot by 5 foot grow area. (18 plants or less)
    • A 1000 watt fixture will supply enough light to cover a 6.5 foot by 6.5 foot grow area. (30 plants or less)
    This was for MH and HPS lights so maybe this will help. It at least answered my question.

    ehhh, id like to see someone grow 6 nice sized plants under a 250watt...also, even a 1000watt with a giant reflector would need a light mover to handle 30 "nice sized" plants. if we're talking sea of green with little plants then i can see how that post would make sense - but plants that yield 1-2 ounces require more space. my 1000watt hps can handle about 10-15 1-2 ounce yielders in 3 gallon pots. my 1000watt is currently growing 5 plants each 5 foot 5 inch (overvegged lol).

    but yea, sea of green you can get away with 30 plants perhaps.

    are you trying a screen of green or sea of green? cause if its a scrog u have to cut down on number of plants cause they grow horizontally not vertically.

    Someone please help to explain the difference between a sea of green and a screen of green. I know that the screen of green uses a screen. I'm a little confused.

    im a sea of green you grow a plant every sq foot roughly. you flower very early to produce small plants, you also trim branches so the plant puts all its energy into one top cola. in a screen of green you veg plants for a while and u weave the branches into the screen until your screen is 50-75% full of budsites and what not. the idea is that the plant grows horizontally under the screen instead of vertically. thus producing a thick canopy right at the screen, so you can keep lights really damn close. most of the branches turn into main nug sized colas. you also top the plants to help with the branching out that u want in a scrog. i am doing a 12 plant scrog right now with 2 600s and im loving it. only thing that sucks is long veg period, but the rewards are going to be nice.

    you will probly be able to get by with not a real long veg time cause sativas fill up screens pretty fast. its just all depending. i would only fill the screen 50% with that much of a sativa cause it will strech a bunch. how big is the area your working with and whats ur budget.

    My grow area is 24 feet by 24 feet. 8.5 feet in height. I am looking to grow 60 plants in soil. So far I have bought 4 1000 watt Euro System 240 Volt ballast. The hoods are pretty large, 6 inch air cooled and reflective. The ballasts will accept both metail halide and HPS. I will be using Metal halide for the veg and HPS for the flower. I am really searching for the best way to gow my 60 plants and get the highest yield. I have the space for sure but do i really want to go with more than 4 1000 watters. I am using 3 gallon buckets.
