Check out greengenes last grow on youtube for a discussion on red supplementation. Not the same product but same concept.
F#&k that!!! Id rather spend a few dollars more(anybody ever watched that movie???)on a legitimate light than take my chances with that one... As a matter of fact,im bout to push the button for something now as we speak...Nope, nothing worse than blurples, you and your plants will love qbs compared to blurples , if they are legit lm301b diodes, thats gonna be a legit setup. I wish you the best of luck, let us know how it goes
I for one am glad you werent having that stroke
post some pics, we all love pics
Indeed we do!!!
I agree with this.
I agree to most of this. For us CMH beat hps hands down but its not a one for one swap, 2 for 3 works great. Our CMH foot print depends on batwing reflectors and works out as aprox a 4x2 with very nice even spread. We even get less par just under the light than the edges so we can really slam it down against the cannopy. We use aisles so this works great with several lights on a beam to raise lower easily together. For these reflectors id go for a 4 foot strip in between. But it would be a bit messy with individual hanging heights.
Love ya Posts Prawn but in my limited experience CMH out yield HPS W for W.
Using cree cobs and reptile bulbs......watch out for frost
Mate, there are some good CMH lights out there with very nice spectra, but in terms of yields the best I've seen have been 14-15oz per 315W, which is about 1.2-1.3gpw. When I grew with HPS, I regularly pulled 1.3-1.4gpw with 1200W – but I grew vertically. I haven't come across anyone growing with vertical CMH bulbs (that's what I would do if I grew with them), so perhaps that's the difference. Since I stopped growing with SE HPS bulbs, DE HPS and DE CMH have come on to the market and are right up there in efficiency, but I believe DE HPS is still the most efficient in terms of umol/j (2.1) vs CHM (1.9-2.0).
