I'll try that thank you siri was in the mid 80F crowd when i switched to led.
last 2 grows, dropped to high 70'sF and my buds have stopped foxtailing. not the same strains so could be that instead.
about a 15 deg day/nite difference
have you seen the foxtail too?I'll try that thank you sir
No but not super dense budshave you seen the foxtail too?
This makes sense, as you know I have the SF-2000 and I couldn't understand why you kept dimming your light. I have my light at 100% after the 1st week, but this winter I had to get a humidifier to keep the humidity up, otherwise I was having issues.My experience with indoor setups is limited as we all know.
But what I can tell you is that at the beginning I didn't believe it needed to be that warm and that humid.
Until I tried it and saw explosive growth and new growth issues dissappear.
I thought it was light intensity. But upon further review of info out there and what happens if its not dialed I found the lack of heat and humidity was causing new growth to come in shriveled.
Maybe it was a combo of light intensity and VPD needs. But the temp and humidity shift made a ton of difference.
This is almost certainly for hps
Source?This is almost certainly for hps
General knowledge and experience. All the top guys are running at 27ish. I have had far better results this run with higher temps and higher rh. Way more compact buds.Source?
this is exactly why I have posted these diagrams, as you can see better photosynthetic rates at higher temps.I have had far better results this run with higher temps
Neither is an analysis of leaf boundary layer resistance, if I pull air through my grow leaves can loose a lot more water than humidity can hold back.this is exactly why I have posted these diagrams, as you can see better photosynthetic rates at higher temps.
But do not mistake them for VPD as rH isn't included.
I had kept my temps at 74f And my growth was slow . A user on this page informed me of a needed temp of mid 80s for led users . I made the adjustment and my plants took off .What temp would you suggest for a LED setup say like a Mars hydro or a Spiderfarmer? And why?

Thanks RIU
Looks like the study was done with LEDThis is almost certainly for hps
Different PPFD were provided with the help of an artificial light source (Model LI-6400-02; light emitting silicon diode; LI-COR), fixed on the top of the leaf chamber and were recorded with the help of quantum sensor kept in range of 660-675 nm, mounted at the leaf level.
I have four different autos under the same temps and conditions in the same tent. Running about 78-80F average. 2/4 are showing major foxtailing and are also the lowest plants from the light. The other two are great. Can only guess the foxtailing two are from poor genetics.i was in the mid 80F crowd when i switched to led.

You running co2? 30 seems high....In a 3x3 with a MarsHydro TSW2000 (315 watts @100% from wall) and a single 8" clip on fan on the floor, my Temps are 30C and 60-70% RH with the tent closed.
Single plant, topped once and LST / cloned.
Seems quite happy.
I run a 4" inline fan for 10 min every hour sucks from bottom to top. 6 weeks in still no need for carbon filter (yet).
With the tent open and a 16" vortex style floor fan blowing in, Temps drop to 24C and 30-40 RH.
