Hi Oldmac ā??
Iā??ve been lurking around here for a while, and decided I needed to join up and see if I can tap into some of your experience. Iā??ve seen that you use a hybrid fluorescent/led fixture and was wondering if there were any pitfalls that you would pass along so that I can jump over them! I have been using a homemade fixture that utilizes (6) 55 watt PL-L lamps, changing out the lamp spectrum based on the plant maturity. The fixture uses reflectors that are 4ā? x 22ā?, and what I have in mind is to build up a new unit that will use (4) of these assemblies alternating with (3) new modules that are the same dimensions, but that utilize (32) 660nm leds on each module (probably the new Osram Golden Dragon +ā??s). I have been pretty impressed with the PL-Lā??s, but they are lacking in deep red and this seems like a good way to get where I want. I grow in a scrog format, so deep penetration is not an issue. Initially, it seemed like a good idea to mix lamps that were somewhere around the 4100k-6500k with the leds, but after reviewing a bunch of spd charts, it looks like there is plenty of blue in all of the available spectrums. Iā??m thinking that using 2700k-3000k lamps would make more of the orange-low red wavelength available to round things out, and still provide enough blue. Iā??d appreciate hearing any input that you have regarding this or any other aspect. Thanks.
