thats a cool pot im unsure what spectrum strawberries would benefit most from

they dont "need it" but in this case it helps to directly raise leaf temp when your ambient air temp is unusually low not uncommon for garden to be in upper 60s and low 70s in winter

even the manufacturers hanging on to blurple have added more and more white diodes to their designs over the years they can still pack a punch as blues are used sparingly and relatively efficient, and the newer reds are a lot more efficient than they used to be

i wouldnt be buying new hps now... but thats a reasonably current system with newish bulbs so ill make use of it... any extra heat 100% offsets space heat requirements for house so no big deal

im about to dust off the DE HPS i used for a year before i got into cobs last winter was too cold and messed with my girls. going to set up the DEs inside a square of cobs and go hybrid just to give myself some options to even out the canopy (tho the ACDE hood is already pretty uniform at 36")...

growing is really not all that hard especially with all the free info on the internet. if youre diligent, have good genetics and a bit of luck its not hard to get 1 gpw with LED on your first try. on a photon basis that would be like getting 0.6-0.8 gpw with HID

yes it can run 1-4

post didnt bother me! sounds like you might be having a bad phone day? hope it gets better! i was talking particularly about the blurple cobs -has anybody digitized the spectra im not super up on plant morphology, just putting out there that that absorbance data has its limitations. Im...

prob still cree or osram top bins

nope. solid only. suerior for our application

So forums where people dont understand LEDs?

leg swep't

exactly but a)most spectrums havent been digitized and analyzed 2)ypf correction is still based off 30 year old absorbance data of leaves in test tubes

no interest. if you ever come up with any specs or data it would be worth the time. I'm literally discussing this with myself and the others while you plug your ears and go LALALALA, so theres really nothing to 'sword fight' about when you dont even understand the concepts we are debating.

what an intelligent and well thought out response replacing my lights with MJ12s immediately!

we are still only guessing in regard to reltaive absorption of real growign plants. and then canopy penetration of different colors. lots of factors. just saying anecdotally if im running purples i reduce my measured ppfd by around 10%. too much monos seems to put them on roids which is fine...

ive got samples of citi and luminus ones here, i just havent had any time to do sphere work on them. and i dont have enough of each to throw plants under and draw any useful conclusions. i think its fair to say that you need less PAR with a targeted spectrum. otherwise wed all be using blue and...

no not really. just another anecdotal grow. theres not a single person on here who doubts that LED light of almost any quality can raise plants through harvest. thats kind of where we were in 2007 or so with this technology. Any "issue" you could think of in terms of plant response, whether its...

do your meds from the Exedra factory go out at "about 10 mg in that about 500 mg pill"? or is there some standard for strength of the the power of a given pill? do the dosage instructions say "about a handful"? Thats the kind of level of info we are working with here. Metrics are useful and is...

sounds about right, i get 1800-2000 at high noon at 5000 feet in summer as well, but as you mentioned thats just a few hours a day, not 12. that kind of light all day for 12 hours would probably be 3X the DLI (anybody who hasnt read up on DLI (daily lighting integral) should take some time to...
