1000's can be adjusted

600w-660w-750w-1000w-1150w

Ther may even be an 880w but I don't remember. Anyway why would you buy a 750w fixture when you could just dim a DE 1k?
Tests show the IR from the 1000w even dialed down is extreme. I would agree otherwise. Price difference is negligible. Also over and under volting in any other electrical system reduces useful life. So if you don't need the 1000's why buy them? Just to dial it down? But then it's kinda all a moot point. I tend to like to be as efficient as possible. Think I've got OCD.

I think market price is a factor. i might grow one strain, and pull 10 lbs. in the same conditions, another strain might yield 8 lb. but what if strain #2 fetches 30% more on the market. a lb isn't just a lb. quality and popularity are very real factors.

Well, if you wanted to crank it up you would have the option with the 1k's.
Who knows, maybe you will need 1000's someday. :rolleyes:

You may want to just get 600's. 750's may be too bright for a standard 8' ceiling, and then you will be dialing down anyway.

Thanks for sharing that story DO IT. The part about the houses being small and the SoG style growing here back then (when clones were still openly sold in growshops) makes a lot of sense. The frequent raided larger grow ups are still usually SOGs, google images search for 'hennepkwekerij' for many examples.

I do calculate the gpw just to get an indication but what matters to me most is the total I get from my setup. I use fans, aquapumps, chiller, exhaust and don't take those into account either. I use 54watt for seedlings, 400 watt for a week veg and a week+ transition, then 600watt for the rest. There's no point for me to determine the gpw other than to compare it to my own previous grows.

I agree with DO IT that most strains indoor can offer a very more or less equal yield, especially with some canopy and bud site control. The space is really my only limit, got to leave some space for air circulation and distance to light, so it's what I get from my space what matters.

It's a more or less way to determine how your production and efficiency is. Jorge does not have a PHD from Harvard he is just a very intelligent person with many many years of experience that no school can ever teach. Not even the cannabis college in the dam. ;) We don't calculate all the watts needed because the light power is what drives photosynthesis without that it does not matter how many other watts of power you consume in a lab. At the end of the day there are 2 types of growers in the world. The first does it for personal needs and use. The second looks at this from a buissines point of view. In which case the first is looking for QUALITY and the second is looking for QUANTITY. It all depends on the grower at the end of the day.

Yup. Ive always went by grams per flowering light wattage per month. For years. Small to big.basement grows and.small building grows. It works.for me. Always has. Its all about choosing varieties, room dialage, and canopy management. How many days/ hours i spend in my rooms really dictates my yields. I was at a certain time awhile back what you would call a.lazy grower and.my yields showed it. I finally got up.off.my duff and applied myself. Yields went.up dramatically. At the end of.the day its all about what you want to do. We are really just farmers. Not really different than Old Macdonald. Lol. Bibs and a pitchfork. Peace!!!!

According to gavita the 750's work MUCH more efficiently in the 600-825 watt range than a dimmed 1000de,even though you can do it the 1k bulbs are loosing efficiency the more you dial them down.I agree 100% that the 1k gavita ballast(remote ballast/not complete fixture)is more versatile,a 1k remote ballast dialed down powering a 600w bulb for example would not have the same losses as dimming a 1000 watt bulb down to 600 and if you chose to run at 1000 watts in the future a bulb change and voila.
Out of curiousity cap are you powering a 1000w lamp and dimming with the remote ballasts or just dialing down the ballast to power a 600w lamp?

Both. I have epap 1ks that I dial down and I have gavita remotes that are 1k ballasts but run the philips 400v 600w greenpower bulb.

You can keep you're GPH I'm with Cap and Texas kid how much weight can be grown per square feet and at what cost. How about 250 to 300# in a 2500 Sq foot area the same area that if you had 60 lights and hit 2.5 a light you would be crushing

Jack, how many watts in 2500sqft are pulling that weight? 60k?

That's what I'm trying to figure out. In a 2400sqft area I would run 80k that would put me at 192# every 60 days. By jacks lowest number(250#) I'm short 58#.

Right now I'm running 40k in a 1200sqft area and doing 96# every 60 days.im short on the 2.5# by 24#. :wtf: Gotta tighten up son.

dayum! OK you have way more experience than me. From here on in i defer to your expertise! lol
