315w CMH Bulbs? Agro vs MasterColor T12/T9

[a senile fungus]

Agreed. I'm not worried about over lighting things, I'm only running 20W/ft². Adding a CDM would take it to thirty- that's still basically HALF of the generally accepted 55W/ft² conventional flatlander grow standard!

Standard schmandard, be the exception to the rule.

That paraphrases my consulting company's mission statement rather nicely.

'If being conventional always worked, no one would ever innovate.'

I think any kind of light mixing is beneficial. I've seen some bad ass grows with mh/hps, cfl/led, cfl/hps, led/cmh.

I think its the overlapping spectrums that make them more successful, and I can't see it going badly in very many ways...

I agree, but the mix doesn't have to be two different types either. Different color temperature LEDs or different color florescent do the same thing.

Here's a trash can outfitted with 55w T5HO fluoros.

I've found the same in a small tent, mixing colours and bulb types increased production and frost. Tried adding 85w of 630/660 nm LED's to a recent run. Didn't get a lot of production but definitely some extra frost and they finished fast, that's one advantage I've seen with the Elite Agro 315's, quick finishes. Plan to add white LED COBs next in the 3000k range and see what they offer.

Currently have a 315w Elite Agro run at 35w/sq. ft. with no additional lighting and expecting around 1 gpw with a mix of 4 strains.

Dude, that is the perfect single plant vert setup for personal grows. That looks like the start of a sticky for the newbie or grow room design sections.

I'm not sure tbh.

I've heard that the 315w CMH is more comparable to a 600w HPS than to a 400w... If that's the case then you'd need 2 315s to replace one 1000w.

I'm also interested in spectrum mixing, let me know what you find.

Figure efficiency of hps is 22 percent and the lec 315 I can't seem to find a percentage listed but all state "highly efficient" .
I've replaced two 1kw hps with two sun systems lec 315 and two Onyx bloom led panels.

I'm thinking I could have gotten by with just the two lec 315 but I had the onyx panels sitting idle and figured wtf...

and then there's the bomber...

And here's a nice option for ballast alone. welthink are chinese but solid as fuck.

They have a complete fixture too. This: http://www.amazon.com/listed-Ceramic-Halide-Lighting-Fixture/dp/B00PTNDKNM/

But not at that price. :b)

In a couple days an auto is going in there...






Eventually I'd like to maybe remove some lighting from it and use it as a mother chamber.

For the next couple weeks it'll be on 18/6 and running during the night to help offset temps in my 4x8 tent!

The ballast welthink won't come up off the listed price. If you're a retailer then you can get them cheaper. The complete fixture is kinda stupid looking and I'll stick with my sun systems (which may even have a welthink ballast in it).

Add a hepa on the exhaust and you could make it a daddy/herm(make fem seeds) box.

Hey I've seen that done! on a trailer park boys episode/movie!

Just FYI, we are all our own business, we are all sole proprietorships. Represent yourself as a company and you can usually get what you want. You don't even have to lie, if they ask if you are a reseller say yes and order 1 more, sell it on ebay.

Really?

I love my trashcan!

HPS is much more than 22% efficient- that index you recall is actually the CRI, or Color Rendering Index, a measure of how well it reproduces natural light. Sunlight is 100, so HPS' rating of 22 shows how much it sucks. The 860W CDM lamps I ran had a CRI of 92- but that did not translate into increased yield. As always, YMMV.

Maybe you're right but I could have sworn I just read efficiency was 22 percent, I may have been a touch wasted at the time. I can't seem to find the page or any page listing the percentage of efficiency of anything right now......could be that I'm a little stoned at the time.

But hortilux says cri means nothing to a plant.
