Yes it's two 4 ft fixtures end to end.
The bench is 12 feet long.

Each has 4 LED tubes.  Timer set to go one at 8 AM and off at 5 PM.
Fixture is about 20 inches above the bench.
I haven't  used a light meter.

The fixture is a Sun System Sun Blaze T5 HO  44.
Rated at 4600 lumens.

Hi Arnold,

Are you using the Agromax T5 light bulb that is 4 feet long?  How many of them to you have in your fixture?  And how many total?  Finally, how high do you have them above your plants?  Do you use a light meter to help you adjust the height for brightness, lumens?

Thanks,

Bern in Williamsburg

Martin:
I'm using AgroMax T5 LED.
411 watts at 6400K.
On whenever the sun is up.
Rimmer suggested not letting them run into night time and I think it has helped.
Plants need a dark period.

Hi,

I've also prolonged my lighting hours from year to year and at least think I get better and better results here at 48°  - one question
though: What type of light are you using? LEDs or something more on the heating side?
