This is exactly what I was saying about only just following what’s going on, lol. Am I correct in saying that far red is outside of PAR and that’s why it often reduces efficiency figures? If so I can see why many companies don’t add far red as despite helping, it would probably reduce the...

To be fair, PAR as I believe is based on old data for general plant growth not specifically cannabis, otherwise we’d see great results off blurples. I admit some of this technical information is a little over my head although I understand the general idea with peoples explanations here. I’ll be...

Compared to the more impressive old highlight uv boards that I we just discussed or the newest highlight 420 gen2 with a broader spectrum and higher efficiency? Because personally I’d still use the original highlight uv over that. I’m not slating Gavita, it’s personal choice but it’s off topic...

I am certainly thankful for those highlight uv boards that I still use and not in a hurry to replace. I was chasing spectrum more than efficiently at first, although as you say it’s great for it’s time without any mono’s in there too. Pretty sure if I wait for some pc blue buddies and throw in...

So it seems to me… with 630nm diodes not being very efficient alongside wide band phosphorus white diodes, adding a narrow band will give a spike that’s beneficial for plant growth in a similar way to a mono led. Although I’m the same way a mono needs to be mixed with whites, these will still...

Good old LED Teknik again, I think Bridgelux market them as cri90 with cri80 efficiency, but I certainly believe LED Teknik has improved efficiency on this idea.

After looking again at the 2700k spectrum I came across, it’s identical. Would these be what your using?

I recently saw the Bridgelux F90 spectrum that’s very similar to this and I believe it’s the same technology, I was thinking it’s a great way to boost the 630nm range efficiently.

This is the sort of technical information you don’t get many other places, that’s a great explanation and although I’m not seeing any damage on my grows, I think I’ll play safe and run one in my veg/mother/clone room. Seems what you’ve posted about uva so far it would benefit both rooms if I...

Honestly, these guys know lights better than anyone. I’m a really fussy over thinker about spectrum and efficiency, I was in the middle of building a complicated light with various different strips and diodes to get what I wanted. After owning the predecessors, looking at the gen 1 boards and...

Just had an extra thought on this, it’s more for my setup but I’m sure others might benefit the details. I have some uva strips that I was using before I got the highlight 420 boards and I kept them in that room. My concern is they’re totalling 16-18w (if I remember correctly) alongside 440w of...

For anyone in the uk, this might be common knowledge but I stumbled across Ecothrive. They sell an organic living soil and some amendments and claim you don’t need any organic fertiliser although you can still use them if you need. https://www.ecothrive.co.uk/

Good point there, I actually went into a normal garden centre on my way home and organic additives are available without the hydro shop prices. Grabbed some liquid seaweed, mycorrhiza and microbes to to try out.

Gotta ask… what’s a sip?

The earthbox does look good, I was going to do something similar based on a soil hempy bucket I’ve used for non organic soil grows. I simply used the 3gallon buckets with a hole 2” from the bottom, used clay pebbles in the bottom and soil on top. They consistently yielded more than my air pots...

I certainly asked in the right place, it was a bit confusing just trawling the net blindly, a few minutes asking on here and I’m shown all the good sources. Thanks

Thanks, I’ll check it out. I’m kinda jumping in a little blindly at the moment so any information is appreciated.

There seems to be a gap in information for anyone wishing to switch to organic growing, I can see a wealth of information that’s over my head at the moment and looking for a rough guide that’s understandable instead of tons of advanced things that are confusing to the newbies and scaring them...

Any idea on a point of diminishing returns? It seems that around 3-4% uva are producing positive results in overall quality and allows more far red that can reduce the overall time and quality. So what if we aimed for 5-6% full cycle or even 10% uva? Then I’m thinking if you could add more uva...

I’m genuinely excited about these experiments, I always think outside the box and find random stuff sometimes helps more than you’d expect. I’ve had a few setback and been proved wrong too, but it’s part of the fun. I’m still thinking there’s a correlation in bud density and orange/red light...
