cybersix said:I used my lux-o-meter (an app for my smartphone) and under the light it said lux were equal to sunlight (I don't remember the numbers).
I saw one leaf has already got longer, not much but I can see clearly the difference since it was eaten by one of my cat, it's the only leaf left and it was really small. I guess the lights should be closer as possible. LEDs stay cool so no danger of burning leaves.

I wouldn't trust a phone app for that measurement.

Totally understand Maurice. I use a "plant lamp" in my T-5 fixtures that spikes Heavy in 420-470nm and 620-670nm ranges

I operate 18- 4ft 2 lamp fixture's, 4- 4ft 4 lamp fixture's and 1 4ft 6 lamp t5 fixture. The cost to replace those with LEDS would be the cost of a High end professional greenhouse lol.
