Wow, that is a good thing.
He ordered a bunch of osram square 660, and the osram 730. I actually split that order with him. He went with some samsung f seriees strips. He has not gotten around to putting it together. Work, family, etc. but should have some results in about 4 months.
My red and far red leds are at the same level tan main lights.. I think that they will not cause any stress...blue light and uva/uvb are much more stressing to plants
Yes.. I agree with you.. in the early days..all people used a HPS 400 over 1 square meter, same potency all flower period...it was easyto use gr/watt but now…..with all the posibilities...Also is not the same a gr of a 15% thc strain that a gr of a 25 % thc plant. When I get nice numbers I also starve plants at stretching time...cause with high ppfd, high temps and CO2.. plants become gigants in few days… aRight now I flower at 10/14 and far red EOD.. which also adds a new variable... I prefer to talk about total weight per área and time used to achieve it cause as you cleverly pointed gr/watt has not very much sense these days. And for most Little growers space is really the limiting factor.
@nachooo
I think the red and far red do not emit very much heat...well if you put your finger on right on it you feel hot...but is not infrared heat.
the slider is aluminium and acts also as a heatsink if you dont run very hard the leds althought they are glued to a big aluminium strip...
Bridgelux availability can be weeks to months. It seems to me we all started to take supplementing “white” diodes more seriously very recently. Very few people have multiple grows with different ratios under their belt to be giving any concrete advice. If you were asking these questions a year or two from now, i think we would find more members willing to give advice they feel more confident about.
@Warpedpassage
I dont think you are going to find very many hardliners aginst the spectrum hgl is offering. Its a whole lot of other drama and as mentioned by others the cheap components in their build.
Oh I read some then got tired of it HGL drama but what it does say is that individually targeted didoes of light colour you seek in LED might have a competing or better spectrum than "full spectrum white" there is no such thing in my eyes only leaning towards red or blue etc . try 4000k the try 3000k to veg see what happens same diode , maybe was anomaly for me but doubt it, learned a few things growing up on a farm but of course stuff grew outside not inside so thats why I am here to learn how to mimic that spectrum, the one cannabis spent 100,000's of years adapting to or maybe millions of years ,not one Samsung decides is good to market next year to keep R and D going through profits.
