Gavita vs HPS Warehouse Grow

@Dr. Who ;

315W CMH lamps are a lot less than $500 apiece, especially if you're buying in bulk for a warehouse. I paid $200 a kit for bare bulb n ballast myself!

Tty I sure can appreciate a much better price point but the fact is, I'm not an electrical kit kinda guy and honestly, I don't even understand what I'm looking at there.
I'm an out of the box type of guy lucky to remember to peel the protective film off the inside of the reflector. I gotta KISS even if its gonna cost more.

Hate to say it, but there are warehouse grows right here on RIU running nothing but 315W CMH lights.

No self respecting commercial grower will have anything to do with MH- that tech is shit and has been completely eclipsed by CDM/CMH technology.

Dunno about your female friend in China, but lots of people over in the LED section are proving that COBs grow great cannabis. Tech is always moving, that's no excuse to wait unless you feel there is something a lot better right around the corner... which is how I felt about blurple LED. Now that COB LED lighting is here, THAT wait is over.

The only way to get good results with five foot tall pot plants indoors is to light them from the side. Even DE won't do it very well.

COB LED can be placed anywhere near the plant, if it's run softly enough it can be all but touching. It's directional, so efficiency robbing reflectors are unnecessary. Lenses and dimming can help customize the light for your growing style. In other words, it will allow the grower to adjust the lighting to his growing style, instead of forcing the grower to conform to its limitations.

Sorry man, I'm just not buying your assertion that DE is the only logical choice for commercial grows.

Oh no! I'm not saying that DE is the logical for comm. ops.....I finished my buying for my new op and had all new HID and then the CDM hit....I wish I had been even 30 days later in my lighting purchase! In fact I wouldn't go that route (DE) on cooling needs alone.
Man the OP and 50 units - sure hope they have industrial roof mounted AC if they go that route....I personally, can't justify that kind of cooling cost I envision...I could be wrong but,,,,

As far as 500 per on CDM that's that Boulder lighting price last I looked on their all~in~one unit...Thanks for the alternate link for those 315's - I'm looking!

You forgot to mention possible rebates from the power company if you're running these in a commercial grow.
Enough to cover most of the cost of the gear you choose to buy.

Now...I've setup 1000 watts plenty of times but they were always air cooled. I can image it to be difficult with 50 of those so what am I looking at in terms of cooling for a bare bulb setup? Split systems or somethin bigger?

How is the setup going? We passed on gavitas. Even on our 80k expansion coming in the next few months we passed.
1. We grow vert and

2. the fucking heat on those things is unreal.

3. I keep wondering if we are missing the boat on the whole LED thing but then again, I still haven't seen LED banging #2 per 1k watts.

Well let me know how it goes! I was looking at some COB units last night and I was like.. oh here is a unit that has good spread numbers.... but it was 1600 watts. I was like.. well, where is the since in that?

Which units are you using and how are you arranging them vertically? One bulb for us illuminates one side of four different plants... so 4k total for most of the plants. Outer ring has 3 per plant. ..

Thanks!
