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.

Anyone ever try to push the LEC 315 footprint to 3x4? If so were the edges airy after harvest? I really don't want to supplement LEDs if I don't have to, but they're looking happy in the meantime. Just started showing sex! View attachment 4404058
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.

Ah found it, Could you be more clear on the valve or two part? What exactly could I search for that in amazon? Thanks.
Valves. 1 to control flow rate from pump to manifolds. Sometimes helpful to have before each manifold if using multiples.

Tubing. (hopfully you can find this for lower price)


For additional anti-siphon, and to help drain manifolds/lines between feedings....manifold is higher than res/planter level.

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
.
Single ended. Here's what I bought.


I would have bought these though now that the adjustable Sun System ballasts are more affordable.

Very nice. Heat is not an issue for me but I do have a portable AC unit in the room. The ballest is barely warm itself

Are those just fittings u connect with the tube? I circled the parts. Thanks man, this is gonna save me so much time!

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!

So can anyone explain what these new cmh square wave ballasts are all about? More efficient? I've only run cmh in the past from magnetic ballasts.

Thanks. I guess that would explain why these 315w square wave ballasts are better than the old school 60Hz 400w magnetic ballasts.
