Look up the mccree curve, plants do in fact use green light. It is beneficial, and not just a little.

Gavita Pro 1000 double ended is probably the most economical/best choice for 1000 watt. The best DE light HPS bulbs are Phillips 1000w DE, being 41% efficient. Double ended HPS is incredibly efficient and lasts a lot longer than standard HPS bulbs. Unless you're considering to make...

LED is depending on what parts are being used. Cheap azz garbage won't outperform CFL I agree. But the highest performing leds stomp the * out of HID. Not cheap epistars in a cramped UFO that are being run too hot, but quality Cree CXB or Vero chips that easily achieve twice the efficiency of CFL.

It's an enormous difference. HID is more efficient than CFL, and so is LED.

Did you fall on your head a few times too much when you were younger? HID is NOT incandescent. A 125W HPS outperforms a 125W CFL. You don't get the power of a 500w HPS with 125w cfl, you get the power of 500W incandescent. A HPS is a bit more efficient than CFL. And I'm not going to be kind...

Vero likes a high current, at high currents they're close as efficient as the Cree chips. Vero being a bit cheaper, Cree a little more efficient. If you run them soft, Cree is the way to go as the efficiency of the CXB scales a lot better for lower currents than Vero.

The white temperatures are fine with the CXB3590 and the vero 29. CFLs and HPS don't have "special" spectrums either and they work just fine, the Vero and CXB series are extremely efficient much more efficient than the good old HPS. The CXB3590 is 68 dollar or so, (At kingbrite on the Chinese...

It would be fine. Mars 1200 draws about 600 watts, that's 37.5 watt per square foot. That's good.

A 700 Watt Mars 2 panel will run at about 300-380 watt. (On a youtube video I see 330 watts being mentioned) You can assume that all energy that goes in your growbox will turn into thermal energy at some point. So a LED panel that uses 400 watt of energy will make your growbox just as hot as a...

re: Picking your brain My post isn't meant to shit on Advancedledlights, I know they're using quality products + they give a 90 day risk free guarantee and have a long warranty. But I don't think the white chips have better efficiency than COBs. According to Cree the XT-E has a max output of...

Nicest things about those cobs is just how few you need and you can do it all in a small package. No need to solder hundreds of leds, just a few cobs and you're done. If you're among the laziest you can even use thermal adhesive and with those Vero Bridgelux chips you can also use those pico...

The tested CXA3050 (precursor of the 3070 series) lasts 36000 hours+ at 105 degrees celcius and 1.5A And lasting as in it still puts out 90% of it's original amount of lumen after 36k hours. At 2.25A and 85 degrees it should still have 80% of its original lumen output after 36000 hours. The...

There's a Spanish retailer that sells growlight fixtures with Cree cobs in them for rather cheap, not as cheap as DIY but it comes close. 200 true watts of CXA 3070 AB bin for 309 euro. (I can PM or if it isn't against the rules just directly link the site) MarsHydro price, for Cree quality.
