Im not sure i understand quote where youre trying to take this but i sympathise much with the feeling of there being "something out there" which is just a little out of ones grasp. I work with someone who has excellent experience and good results in growing by just looking at the plants. But his...

Nit picky is where the real information and knowledge is. Results seems to align with where my working hypothesis is; green builds fiber/stick/woodiness and diverts flower energy towards more structure related things away from fragrant flower. After dry and cure see if you can see any...

Yay! Nice branching and plenty of tops. Perfext looking green leaves, this should be a good one. I can see 3 plants, right? What potsize?

Im not so sure about that. Whenever ive seen a china light properly tested they test way (10ish %) bellow their advertised spec. Mars for example, tested in a growoff by the GLA guys. Way back when peeps here would try to figure out if there was any point in using Alibaba suppliers there was...

As in hot air solder? They are not great if you have a big metal pcb. The pcb acts as a heat sink making it hard to reach good temps. Im not really liking what the wires look like here, a bit burned and melted. Make sure you take care in use of it. For soldering wire difficult soldering pads...

Of course bud. How far are you from Berlin, ive got a small base of friends there?

If the icmag cup is on in Barcelona again next year maybe you could do a little field trip and come down to do some research? I should have my place back by then and be able to host you. But its quite likely to be in Germany what with legal green so maybe ill end up heading up your way :) The...

Hey Cobby. Never saw your thread. Since i know you well id rec looking into two approaches. For sift: there are tumbler machines available. Ours was quite expensive but highly diyable. Its like a box with an electric engine on slow, rotating a drum where the outer walls are made of mesh. Think...

Mine were Alibaba fotops, large boards, like 5 qbs side to side on wide side, with 2mm thickness. They seemed to run really well up to 200w with no heatsink but there must have been some kinda deterioration. Alibaba quality obviously not the same as hlg. Not having a go at the diode infact im...

We dont do full hydro only coco but its always good to know what the alibubbers have and what actually works. If you can get that one product on alibaba that doesnt break down the savings are very good. I will bookmark your comment with the link for reference:)

Nice! How much is the power consumption? I see 270w of refrigeration, is that it? Or is this how much it can cool?

When it comes to benefits of high cri growing its important to understand its not the higher cri value that affects the crop, its the red content, how it peaks around 630, close to chloropeak, and not the actual cri number. In my understanding: 97 cri doesnt change red content very much from 90...

The power supply tends to crap out before. Ive hung 10000s of diodes by now, only diode ive seen die in our own place is china diodes (from 2017 so about 7 y o by now) lm561C, without heatsink. Everything else still lights up.

Youre in Spain, right? High cri always seemed more popular there, cannabiscafe forum is full of it. Did you see difference in yield and density aswell? If its still in progress update let us know later :) i love picking up peoples experience on spectrum differences. Imo 97 cri is not worth it...

I have it from someone who got a gonio and measures efficiency professionally: samsung diodes tend to always underperform their spec and data sheet. Not by super much, but if a bin is +-7 percent they are always in the lower range. Nichia tend to over perform, and also sells their diodes in...

Did you have a look at the study brazzik posted? There some info regarding spectrum and how much it moves the dial: honestly, not a lot. The one thing that correlates more with yield is wattage and how much light hit your cannopy. A really souped up spectrum may move that 10 to even 20% but...

I like the euphoria sativa/hybrid thing best. My favorite feeling from weed is that relaxed, zero anxiety, weight lifted from my shoulder, like i have the sun living in my chest, smiling at the world and loving everybody. Too heady, amnesia style and nonstopp head is not my main thing. Ive heard...

I pretty much smoke weed every day. Went home to scando where i dont have any connect and really prefer spending time with the fam rather than being stoned. Came back and smoked some new sativa genetics we acquired - old school genetics, all the different parents and and grand parents of that...

Its actually likely to happen much sooner, not cause they wear out, just cause you end up feeling like building a new and better light. DIY is a drug, its almost as strong and addictive as nostalgia

Diy was very popular a some years ago and you could argue that the way modern led lights are built and designed comes from the work of many of the older posters here on this forum. Im talking about Growmau5, SuprasSpl, Rahz and many more. Back then leds were either kinda awfull blurple lights or...
