Thanks for the compliment.

I don't know anything about that source of lamps, but their claim seems a bit optimistic, IMHO. Maybe 2:1 efficiency but 4:1 would be stretching it.

After following Weezards posts on LEDs elsewhere I'm wondering if I have a bit too much light in my tent so I've ordered a lux meter and will take some measurements when it arrives.

Watered the front plant with 1/2 ususal amount at 1/4 nute strength this morning. rear plant has about 1 more day until it needs water/nutes.
