I run a 6 bulb 4' T5 for side lighting along with my 2 315's on a 4x4. I just pulled a monster crop of 6 plants.CMH loves company.
Slammin the sisters with a supplemental string of 5 cobbies cranked to 250w.

So can ya'll catch me up real quick on the current cmh technology? First off, are there some brands that are way better than others, or are all ballasts pretty much the same, and the difference is in the lamp? What about vented hoods, I don't really see those much with 315w setups, not necessary? Finally, how does the 315w cmh compete with a 600w hps, is it really a close equivalent? I run a 600w hps, and bought a 400w mag ballast a few years ago, and ran a 400w Philips MasterColor Retro White lamp (now discontinued), and it didn't quite keep up with the 600w hps, so went back to hps.

Your plants look beautiful. I had 2 315's in an approximately 3x8 closet, and was really impressed with the penetration of the cmh lights. My lower and outer buds were still really nice. I'm trying all quantum boards this round, and they don't look quite as nice. Here's a pic with the 2 cmh.

I would stay away from the super cheap China brands other than that it is the bulb that makes the defense. Most like the Phillips. I run Hortilux bulbs myself. 315 compares very well to a 600. 2 315's I think is better than A 1000 in many ways. The ballest run very cool that's why there not offered remote, there's no need. I got away with being less then 12" from canopy with AC blowing across them.

The bulb does make a defense, lol. The Phillips is the one I use. And they do have remote ballasts for cmh. That's what I have now.

Is it a single or double end? Not aware of any single end (true CMH) that are remote. Nice
Just checked Google and there are some excellent deals on there right now. WOW

Valves. 1 to control flow rate from pump to manifolds. Sometimes helpful to have before each manifold if using multiples.

That is a combination of hose, t-fittings, reducers, and zip ties or hose clamps to keep things from leaking. Not pretty, but functional.
Good luck on your project!

Oh, ok then I guess I'll go dig thru hundreds of pages of posts. Thought someone might be able to help with a simple answer to a straightforward question.

Thanks. I guess that would explain why these 315w square wave ballasts are better than the old school 60Hz 400w magnetic ballasts.Wave Shape and Frequency | EYE Hortilux
