Ok. Thanks for the response.
And what kind of coverage does one of the 14000K bulbs cover? I grow in a tent and am in the process of ordering a very nice LED light by Optic (360 watt Vero 29). And I was planning on getting the 4000K color temp.
And, when you say "HP's", do you mean "HPS" (High Pressure Sodium)? Honestly, I have grown under Metal Halide bulbs that are quite white/blue in color and the plants under them did well. Then I switched to a HPS conversion-bulb (works on the same metal halide ballast) and also got good results. So I think the plants mainly just want a high intensity light of some kind and they will grow well.
And, as far as I understand it…"HID" means "High Intensity Discharge" lights and it is a general term. "HPS", as I stated, means "High Pressure Sodium" and that is a very specific type of bulb. -just so we can be on the same page of terms!
Your post is certainly the first one that I have seen that made a claim that runs almost completely contrary to what most growers have settled upon -in terms of growing under artificial light. Of course, sunlight is always the best light! But you can't always get it for 12-18 hours a day and all-year long (cloudy days, rain, etc.).
I am a bit skeptical, to be honest, but I would be willing to try one of the bulbs for an experiment and see if it makes any difference once I can cut some clones -It wouldn't do any good to grow separate seedlings -which is the stage I am at now. I have a bit of an excess amount of plants this run so it might be fun to try it out on my next run.
