Supra, FYI I called cutter. They will do any LED on any compatible board they sell as a custom run even in small qty. They dont charge much extra for custom orders .... I was considering adding some XPE2 red and XPE photo red to my mostly cxa3070 3000K setup and was planning on going with...

Its worth mentioning that off peak power does not really work that way. There is a separate circuit and meter for off peak usage in your homes electricity box. Generally only hot water is connected too the off-peak circuit and meter. The power company sends a signal that triggers the hot water...

I own an older AT120RB and an older A51 SGS160. My understanding is that both draw very similar actual wattage. I have owned both since they 1st came out and they are used in a dedicated flowering space side by side. Plants under the AT120RB do a little better overall but there is only a small...

I agree completely except I think the hlg-120h-c 1050 is a better match for 4x COBs. Its true that the efficiency stays above ~92% until you drop below about 70% load. However if you plan to run the light dimmed down then you will be running well below 70% load with the hlg-185h-c. I'm running...

You could use the HLG-C 185 1400 to drive 3x 3070 @ 1.4amps each. I'd suggest also adding some XM-L2 or XPL diodes to bring the series voltage up close to the drivers maximum where it will run at max efficiency.

"Instead of 6 LPC drivers you could run 3 3070 in series on the HLG-120H-C1050* (high voltage) * = A or B" I have 2 lights that I've built using the HLG-120H-C1050 driver on recovered copper industrial heatsinks (like a cpu cooler but 4x the size and weight). This driver ideally works with 4x...

Check out the blower thats sold by Steves Leds. Its basically a computer style centrifugal fan. You would have to custom make a mount to attach to the Phat filter but that should be pretty easy. You may need more than 1x blower for the CFM required ...

It does not really make sense. CO2 enrichment allows photosynthesis to take place at a faster rate by supplying extra C02, extra bright light and higher than normal temperature. If you don't supply all three ingredients at the correct levels most of the benefit of CO2 enrichment will be lost. In...

It should not be that hard to dig through the tarmac and repair it when your done. I would imagine that a sledge hammer would do the job. Can you not go around the tarmac?, running a mains power cable along the fence on one side of the property and then underground too the shed might be an idea...
