RH for me is a problem. winter RH two rooms away from woodstove runs about20% . but my plants do well.
as they get larger, and fed larger amounts the RH will go up to about 40% . but drop until next feeding. i dont want to buy a humidefier.
i keep it cheap. KISS grower.

Oh, you are lucky... I'm on the opposite side... too high RH... so I've been slowly saving up for a good room dehumidifier, and a better extractor.
I had been reluctant about the dehumidifier cuz i also want to keep my monthly costs as low as possible... but after getting a bit of bud rot last run, i got my wakeup call... and during the pandemic it has been difficult for me to find calcium chloride which i had been using successfully to lower the tents RH... so dehumidifier it is.

UPDATE

Yesterday was day 41 for this little Deez Nugs. I did a bit of vacuuming over the weekend and damaged a few leaves by mistake, but other than that, i think she's doing well.
I do feel she's asking for a bit more nutes so today i prepared a new reservoir with 50-60 ppms more of MC1 for a total of 470 ppm / 0.94 EC (85 tap, 385 MC).
Other than this, it's all pretty much the same. Her tallest top is now 23 cm / 9 inches from the light, so getting around 600 ppfd at the tallest top, and 150 at lowest leaves, for a of about DLI of 9-39. Might do a little defoliating during this week after I see how she takes to the higher EC.

And well, some pics from yesterday...

UPDATE

Day 45 - Removed six big fan leaves to let light through a bit better. The 1-bladed leaves of the first node are starting to yellow and she has gotten much closer to the light, so i feel she needs more nutes now and this week's increase wasn't enough. Today I'll be increasing the tank/reservoir MegaCrop EC from 0.76 to 0.84.

Looking good! Your cord management is way cleaner than mine.

I do not believe she can look any happier.

UPDATE

Day 48 - OMG, This Deez Nugs keeps growing taller. Didn't really expect her to be this tall (not that it's huge), and it seems she might also go longer than expected.... now I kinda regret not having done some LST or topping her. But she is really nice and now starting to show some resin building up. Smelling pretty sweet, too.

Still only getting MegaCrop 1-part version 1, plus 80-100 ppm tap water, and hydroguard. The MC EC increase for last Friday (from 0.75 to 0.84EC) doesn't seem to have had any negative effects, and might not have been enough actually. Main cola top leaves began getting lighter after this, but I also noticed she got closer to the light and pH in the tray began rising more than before (tray was at 6.5... while tank/reservoir was at 6.0) so I assume they getting lighter was dute to this.
But the pH problem seems to have worked itself out by now since now tank is as should at 6.24 and tray at 6.35 , and tray ppms are usually about 50 ppms below the tank/reservoirs ppms, so I expect I will have increased the MC EC to 0.9-1.0 by the end of this week .

I'm letting her get as close to the light as possible being careful of heat stress, and heat still doesn't seem to be affecting her much. Today her main cola is 10 cm / 3.9 inches from the light, getting about 950-1050 ppfd, for a DLI in the 60s range; while the next tallest tops are getting about 500-600 ppfd for a DLI in the 30s range.

BTW, she's not in the usual 2.2 gal / 8.3 Lt autopot pot i use, she's actually growing in a 1.8 gal / 7 Lt pot that is only filled up to 1.3 gal / 5 Lt.

QUICK-PIC UPDATE

Day 51 - Still seems to want more nutes after increasing MC to 0.94 EC / 470 ppm.

I do not think she can look much better, honesty.
