You won’t find many facts being reported on Fox News.

The metric is still comparable even with no veg time. Light efficiency shouldn’t be taken in a vacuum. Some super efficient LED grows might need supplemental heat in the winter, where an HID grow may not. The reverse applies to air conditioning in the summer, where it may be needed in an HID...

Yes. Photographs during lights on.

Fair enough, thank you for your contributions, I appreciate forums like this and folk like you providing frequently useful information to others seeking learning and understanding. But I still suggest anyone else interested in LED and technical lighting information to spend time in the LED...

If you would like to learn, spend some time in the LED subforum in the indoor growing forum, I believe you will find it very informative. There are very bright people discussing all aspects of LED technology and research and science. Definitely worth a visit.

Grams per watt metrics are misleading because the length of the veg cycle is not considered. For example, one would expect a higher yield from a CMH grow that vegged for 6 weeks, vs. 2 weeks before flip. IMO, a more accurate metric to use is grams per kilowatt-hours, and to include electric...

Classy.

What is the wall draw wattage of each of the lights?

Total power consumption of your lights is what matters. 520 (wall draw) watts of LED will make as much heat as 520 watts of T5 or T8.

Lol

What are the *actual* power requirements of the lights, based on the specifications?

@DillonGrows if you look at the g/watt yield of your HPS and LED grows, they are almost the same. HPS - 300 grams / 400 Watts = 0.75 g/watt. LED - 210 grams / 290 Watts = 0.72 g/watt. The HPS and your blurple LED probably have similar efficiencies.

Northern Lights auto from CKS. This is the furthest along I’ve managed to get an outdoor grow.

The OP said he was using six (6) 42-watt bulbs in his original post:

A sheet of paper is 11 inches by 8.5 inches.

Why are they calling it 100 watts when the actual wattage is 50-55 watts? There were critical reviews, including one that said don't use for cannabis.

If your minisplit ac system cools well but doesn't dehumidify effectively, it is oversized for the cooling load. This could be corrected by modifying the minisplit to more effectively remove humidity, which will make the space more comfortable for you and reduce power consumption.

Not quite sure of the geometry you are describing, but if two fixtures rated at 500 at 8 inches are pointed at the same spot 8 inches away, seems the maximum it could be is 1,000. But a plant isn't a spot, and neither is the output of the lights.

Post this in the LED sub forum. It’s in the indoor growing forum.

All currency is “fiat”.
