this particular 'test' may lack validity, but the superior growth rates of hydroponics over soil have been studied and confirmed long ago. It's not a controversial take, it's just fact. All other aspects (favor, aroma, cannabanoid profile etc) can be debated and argued about, but those were...
i have a strain that turns into a bush with no topping and no training. as long as it gets sufficient light I tend to get 8 to 12 hand grenade colas. it's crazy.
I don't know if you got a defective unit or if there was user error, but my apera meters have lasted me over 2 years with zero issues. keep them clean, store them correctly, and calibrate them periodically and they are great.
for those not in the know who don't understand higher ambient temps with LED.... it's simple. HID puts out sufficient IR to heat the leaves of the canopy to a temperature above ambient temps. so ambient temps of 75 under HID will result in leaf temps of 80 to 85. LED doesn't put out IR for the...
I have a strain that does that almost every time I run it and it always grows out of it. not saying yhats the case with yours, but I agree with letting it go a while to see if it sorts itself out.
Temp is spot on. rH could be a bit higher but I would call it acceptable. a lot of people swear by 60/60 and I've had good luck with it, but 60/50 is in the right ballpark in my opinion.
I run most of my boards at around %80 to %85. allows me to use more boards for better spread, the diodes run cooler which adds to the longevity of the board, and less ambient heat from the heatsinks and drivers which keeps cooling costs down.
