I think it is a negative pressure issue. So the airflow is better just like a pc would do. But now nothing blowing the plants around. Now temps are 79f with the hps on and with fan on it is 82-83f. My hps cycles on and off (6 hours of 12) and the led stays on 12. Trying to keep temps down since my ballast is heating up really hot so I don't want a fire and just have it turning off and on haha.
How do you get on with splitting the light cycle, I've actually thought about splitting between 1k/600 during the summer, my ballasts are dimmable or run 4/6/1k + 10% super lumen boost if you like so it can be 440/660/1100w.
If you don't mind would you keep us up to date with the progress/results, i remember vaguely reading about using different wattage each day it was positive info hence its still knocking around in my head.
I've seen plants growing nearly into the light (not my ones) and they looked healthy enough
68-77f (25c is 77f) is the sweet spot i have kept though at a higher temp there is more transpiration closer to 80 but this can cause the stomata to get thicker cells.
I would like an answer for my question from a more experienced led grower. You can get light burn anything closer than 12 inches some strains are more sensitive like indica (these are blueberry). They are in week 3 of flower so putting them at 12in now is what I did and if it is looking like burn tomorrow I will move them back to around 16.I've seen plants growing nearly into the light (not my ones) and they looked healthy enough
So within myself I know they can handle more heat but I don't want to scorch them, i dislike having plants with nute, light, or windburn, once it's done you can't reverse it.
My last grows I maintained the air temperature not realising that the radiated heat can reach 30c so ideally I'd like a number so that I can set the light as low as possible?
Of course I've never used led,s for growing however heat is heat and radiated heat can't be blown away.
There is no end all be all answer. The plant itself makes a difference, sativa leaning strains tend to want and tolerate much more light than indicas.
My thoughts exactly I think to get the best you have to grow the strain a couple of times to learn its traits of stretching, feeding etc :thumbs:

@GrOwThMoNgeR blueberry is a beautiful smoke, its been a few years but memorable, around 20 years ago blueberry wasn't very stable allegedly so I never tried it, I'd expect its different now I just might go for blueberry next time around, it's yummy
To cool the LED probably, extending it's life.
will try and give an update in next couple days running now today
yea you're most likely right, well i turned back on the fan
this is the strain, smells good and very stoney high, very relaxed feeling, an afterwork strain, sleep is deep
