Just located the UFO box
It has Bridgelux 90 @ 1w diodes 455-470 + 630-660 20 blue + 70 red
Positioning the vanity fixture over the ufo put the screw bulbs too close the canopy (caused some bleaching). Solved that by adding a couple smallish heat sink risers on top of the ufo (but below the vanity fixture), but doing so moved those bulbs too far away. What to do?
Aha! I figured out why I did not buy the 23" extenders, I can simply screw 2 shorter ones together, which I did this morning, putting the 6.5watters right where I want them below the canopy
Weather has been quite cool here for 5 days, so growth has stalled, but we're warming again, up now, so should have some nice growth by Friday.
Secondary growth is very full. Each plant has 5 @ 6" secondary branching + several @ 3-4"
Wondering whether the 20w of blue is too much, and how to compensate. The diodes are protected by a glass (could be clear plastic). The blue diodes are concentrated in the center ~ 4" diameter, so maybe tape something over that area to block the blue. Anybody?
