I measured the light at the top of the plant and got 33,000 lux.
I figured that's too much so I raised the light.
There, ... 15,000 lux.
Temperature and humidity look OK.
75* would be better, personally consider 80* the high point to avoid.
What kind of soil mix are you doing these days? I know you are doing your thing, and will likely continue to do so, but I'd suggest you consider changing up your grow medium/style a bit. Specifically I'd suggest moving over to a coco/perlite media
with a drip system and forget the SIP. I've tried hempy a couple times, which is pretty similar to SIP, in fact I have a couple of hempy going now as an experiment. But I find that coco/perlite with a hydro drip on a timer, gives the best results every time. The thing is, you drip like 3 times a day for short intervals, and all the root surface gets new nutes. On the passive SIP or hempy systems, you reply on the plant to pull up nutes from the bottom or the roots, or hope for osmosis, but drip the nutes flow from top to bottom.
33000 is alot, i would say a little early for that much but flowering that should be great.
in veg my LED puts out about 17k-18k lumens at canopy, and my CMH is around 20k at canopy.
75* would be better, personally consider 80* the high point to avoid.
little more humidity wouldn't be a bad idea. 55% before budding isn't bad at all. 40% is a little dry.
I don't think I want to bother with pumps, timers, and sprayers.
I like the simplicity of the SIP cooler.
I just add more nute solution when the float gauge hits the bottom.
75F would be better if was using HPS lighting, but with LED 80F is actually better, so that he can get leaf temp up and stomata open. Lack of IR with LED lighting and all that jazz plays a role in transpiration.
... just dealing with the dryness by spritzing the top of the medium so its more even in dry out and the top isn't crumble by the time two inches down is ready for water.
but i will say a cheap wallymart airpump and stone wouldn't be a terrible idea.
you realize that is a VPD of like 1.65-1.8something.. its like Kenny loggins all up in there taking you to the danger zone. getting to 55%-57% will get you out of the zone without effecting temps, alternativly the temp could be brought down while humidity stays the same. the 1.15-1.25 range...
@pcbuds Got some ideas to manage the heat a little better.. whats the spacing between the panels? enough for a 40mm or 50mm computer fan to fit?
ya havn't feed the closet plant yet?
window still looks hurtin from the heat, but not much you can really do I'm cooking here by my computer.. ac is going lights ain't even on... and if i go near a window i feel like i'm melting LOL
