im wondering if 1 could replace my 1x1000watt HPS with 4x250watt HPS lights. or is 1 HPS ballast able to run more than 1 light if the lightbulbs total watts are equal to the output of the ballast?

Whats the Lumen output on the 250 you are planning to buy? Compare that with the 1k *roughly 120k lumens*. Take into consideration heat and how much of a hassle it would be to move 4 lights instead of one, also you would have to keep the 250s closer to the plants *like 4 inches or so*

4 250w hps are not the way to go if you are trying to replace you 1000w. Why do you want to change your light anyways? The 1000 is a great light that if properly coolded will produce buds the size of your forarms. If heat is an issue look into 600w digital system. They are great and with a good bulb can produce within 5% usable light as with a 1000w magnetic ballast. I just bought one and it puts of little heat as in compaired to the 1000w magnetic ballast. Hope this helps~
peace

im thinking about trying something i saw on this site called BOG. ill link at the end of post. he is pulling alil more than .5 grams per watt. doing it his way. i have an extra 1000watt ballast so i was wanting to replace that 1, 1ooo watt bulb with 4, 250 watt bulbs. so i could get 4 grows going in a BOG style.
i dont know what the luman output is on a 250 watt HPS light is, but ive been useing 150,000 luman hortilux eye bulbs so far.
the ballast i want to use for this is my magnetic ballast. i have a digital ballast that i use for the crop thats going now. the magnetic ballast is just a backup if my digital poops out on me.
A new system for growing indoors

Yeah I still am not to sure of this Barrel of Green stuff. Having more than one plant per pot goes agianst everything I have researched, read, and grow by. Good luck with that. And plus I have seen more efficent ways of growing and more grams per watt. Yeah .5 per watts isnt bad...but its not the holy grail...... i sure as hell wouldnt buy a bunch of 250w hps lights to max out at .5 per watt!!! just some food for thought.

by his math i should be able to get alil more than a pound from my 1000watt ballast. and be able to do that with 16 plants. right now ive got 24 growing under a 1000watt hps and might get 10ozs. im not saying .5 grams per watt is the end all be all of growing but its a hell of a jump from what ive got now.
i too have read all about not haveing more than 1 plant per container, but i really dont see how it could be that bad to do it,,,, if you start with good female clones and grow them very small.
im just a bottom line kinda guy and pulling 10ozs from 1000watts vs pulling alil more than a pound has my eyebrow raised alil bit. i know 10ozs from a 1000watt light is kinda sad but it was my first hydro grow, and i picked a bad strain for indoors.
i want to try the BOG idea but with a few changes like no soil. seems easily tweaked into a hydro setup. that would do away with all the worries of more than 1 plant per pot, and injected CO2. seems perfect for both.

Wow instead of changing lights I would just try to improve on your mistakes. A pound with a 1000w light should be a task that is done with ease. Not knocking you or anything, just so you dont think I am. I grew 6 NL and got over a pound from a 1000w HPS. Have you ever tried soil?? Little more forgiving.

I think you have been baffled.

Unless you are restricted by height requirements or have an odly shaped grow room I would stick with 1000W. As for putting 4 250s on a 1000 ballast thats a good question, with floresents you can run multiple bulbs off of one ballast so I would lean towards the; It probably wouldnt blow up side.

So with that out of the way, your low yeilds are probably from going Hydro with little experiance. Hydro is very touchy and takes alot of trial and error before you will see the yeilds it can produce. As well the strain you use will make a big diffrence in yoour end results. Some plants have better yeild with less potency and vice vers.

To the point. If you dont have many grows under your belt dont start switchin shit up on your self now. Stick with what youve done so far and figure out where your weak points are. There are 3 main factors Light, CO2, and Nutriants and you have to Experiment, Experiance, and Learn to ballance them for the high yeilds.

Happy Growing

were you saying to wire 4 250 w bulbs to a 1k ballast? if so you will be out some bulbs and probably hurt that ballast. the bulbs will burn out in a few seconds with the pulse from a 1 k ballast. and a ballast is not designed to run more than 1 bulb period

Oh man I thought he wanted to go a buy 4 400w ballasts. Yeah that shit aint gonna happen using only one ballast. Dude the more I think about that BOG the more I begin to think about its flaws...its not worht it unless you are trying to grow very little amounts. Plus with a 250hps your buds are not gonna be that great...comapired to a 600 or 1000. I mean better due to the density differences. Stick with the 1000w and maybe try at soil; something a little more forgiving. Good luck man!!!
