Really outstanding stuff going on here, pulling up a chair.
I've got Kush Mints going right now too and the node density is just crazy, super bushy plant.

I got through most of the pictures in this thread, but didn't have time to read, so apologies if this question has come up, curious how much warmer it is in the tent than outside of it?

Edit: Well, had I read the first post I would have seen room temps are 60-72 F.

Welcome and thanks Catahoula. I'm really happy with the Kush Mints, I have four clones just flipped to flower in RDWC

It's hard to tell you how much heat the vGrow adds. I don't measure the temperature in my office. I feel the 'outside temp' reading from the vGrow is high, probably influenced by the vGrow itself. Also, I've never had the light over 75%. My gut tells me it's about 5-7f higher in the tent than my office when the lights are on. That will also depend on how much the exhaust runs, how high, etc. I have an oil-filled heater in my office now to keep it warm enough to get the tent up to 78-80f when the lights are on.

Do you do any pH adjusting to your nutes or the res over time, this being coco?

I pH and adjust the nutrients before adding to the vGrow. I mixed up 4 gallons of fresh nutrients yesterday and measured at 6.2. After bubbling for a day, today they measured 6.5. I added around .3ml pH Down to get the four gallons down to 6.1 before taking a gallon to add to the vGrow.

I'll measure them every time I take a gallon to add to the vGrow. In the past, the pH drops over the next couple of days. I'll end up adding a little pH Up for the third gallon. Knowing it has the tendency to drop in pH, I'm shooting for 5.9-6.1 when adding to the vGrow.

All that said, I may have just been able to add the nutrients without pH'ing. They never read above 6.5, so they probably would have been fine. I have the pH meter out every other day to check the RDWC, though, so why not?

Thanks! I was wondering because of GDB's LazyMeter™.

Mind if I put that info in his new thread?

I'm reading along Shed!

And I bought new calibration and storage fluids for my Apera Ph meter.

The Lazy-Meter and I actually had a civil discussion about the Ph issue that comes with using coco and he's cool with it because of the reservoirs.

He's a calculating SOB!

Oh cool! I'm glad you're not just on arguing terms. Will you talk about it in your thread for folks taking inspiration from you?

I'll try Shed but that's more typing.

Unless...my post on the subject reads strangely similar to BudMan's take on the subject.

Just kidding BudMan. I would never plagiarize your work. But I might cite it and link to it! :Rasta:

Feel free to plagiarize me! As long as the information gets out there do whatever is easier for you.

I'm not wired like that BudMan.

I must ensure that credit is given where it's due. You're due some! :Rasta:

Thanks a lot Dust. She's been fun to play around with, almost like a bonsai tree.

Cannapot Kush Mints fem photo (Moira)

Date: 2/23/24 - Day# 100 - Flip day# 61 - Flower Day# 45
Medium: 3G pot w/ Coco
Nutrients: 5.5MC+1SC+.5MgS = 131N-64P-232K-124Ca-61Mg-82S
Light: 75% Flowering spectrum 12/12 (1100ppfd / 45DLI)

It feels like she's on cruise control now. I'm really trying to keep her green for as long as possible so I'm watching for any signs of issues. She still looks spectacular and is really starting to fill the vGrow with lots of frosty bud!
