Hey SSHZ just out of curiosity, what are your temp differences if you know them, both room temps and leaf temps, your HPS vs LED

I have 0 doubt that you will hit that mark.I just want to hit the 2 lb mark per light......that’s always been my benchmark. Over that is all gravy!
There is also the new equipment syndrome makes one spend more time in the grow room. I think a couple runs and you know what to expect you will be a happily converted LED grower.If I get over that mark, and the quality it better than under HPS, I’ll be a happy guy. Growing under LED’s has turned out to be more involved and more work day to day, I just want to know it’s all worth it in the end.
I have to watch this second part... It sounds like exactly what I was wondering about your lights.2nd video is also worth watching........ basically it details the advantages of far-red lighting in your LED's. It appears Gavita knew what they were doing when they chose the diodes they use in their LED's. Thanks Milson, good stuff!
I know this feeling all too well haha. I am looking forward to fall already. Positive vibes...it's one of the reasons I switched from HPS- to get a better control of the room heat. Funny how that worked out in the end- I'm running hotter now. LOL
Just my input not claiming it's fact but more how I understand it. Photosynthesis makes sugars. Each leaf that if photo synthesising is contributing to this and those are the leaves being exposed to the most light. The over all photosynthesis will increase overall sugars and starch production so IMO removing the leaves that are not contributing but are using sugars is the key. This could mean removing large leaves blocking penetration. No loss to overall photosynthesis as the lower leaves will now gain but changing where it happens and the need for transport. To me it would seem import to strategicly remove leave to spread this out through the plant not just at the tops where during the Calvin cycle it has to travel all the way to the roots.So here is something that comes to mind watching this grow, First SSHZ your doing a great job and thanks for posting all the info, But here is something i'm curious about because I never done any testing under LED light, some of you may have and know the answer to this. and thats the relationship between the LED lights , Photosynthesis and sugar production. because thats king and from what I see the LED lights create some different moving parts vs HPS
The first thing I notice was the smaller stockier plant with lots of new leaf growth , that great but new leaf growth (younger foliage ) takes a lot of energy, meaning sugar that the plant is making, but there is a lot of competition going on as well in the rest of the plants for sugar as well. So thats one thing I'd be testing is sugar levels in the plants sap at various points and times to see where its at.
Another aspect I'd be curious is defoliation after flip in to flower, After flip the bud sites require large amounts of sugar and are probably the most important to receive the sugar to grow big add weight,flavor etc etc , but there is still a big demand in the rest of the plant. The only reason I defoliate in flower is to redirect or speed up sugar production in the plant, With all the leaf growth under LED light, that is creating a strong demand for sugar, at the same time the bud sites are as well as the rest of the plant. So I would think defoliation just became a whole lot more important, because if your removing the wrong leaves you could be hurting sugar production, So I would think it would be most important to be removing the younger new foliage that is taking a lot of sugar to grow as opposed to the more established leaves that are making you sugar. So thats eliminating a need, and redirecting or making more sugar available to the buds sites giving better bud production. Also over defoliation in total, hurts sugar production. I'd be shooting for 12% or better sugar levels in the leaves.
Do you happen to have a refractometer SSHZ to check sugar levels, It would be interesting to see how the levels are running under led, they could be high, right on or low, It would also be neat to see how the growth of the plant with all the foliage and multiple defoliation's are effecting sugar levels in flower.
