Ahhh, the exact intel I’ve been craving. I hope my little guy survives long enough that I can tell this same thing to some other noob down the road.

OMG yes. I know it is much more but if you can get the whole kit with soaking solution and those Kool calibration tubes. The one you choose is a .1 tool which is fine for cannabis. The 60 is a 2 digit accuracy unit but both have replaceable tips

Question: I need to run ductwork about 15 feet from my tent through my basement into an unused chimney opening. My basement is around 60-65 degrees all year long and right now I’m keeping my tent at 75 degrees and 65% humidity. At this point I don’t have the exhaust fan high at all, but I’m wondering if I need to be concerned about condensation pooling up in the ducts and causing a problem. Anyone have experience with this?

Honestly looking at your setup you can save the hassle nd just leave it as is, the room outside the tent seems a good size should be plenty of fresh air getting pulled in,
But also I see no harm in the ducting issue if any moisture was to settle it would be absorbed by all the dust nd fluff in the duct if any nd dryer by the air I’m no expert but should be fine in my head

Oops, my bad. The ducting I was asking about would be the tent exhaust, which is blowing really humid air into my already too humid basement. I’m just looking for a way to get that humidity out of there. Right now I have a humidifier in the tent, which is being lightly blown into the basement where I have a dehumidifier struggling to keep up. What’s weird is I’m pouring the water from the dehumidifier into the humidifier (plus a little extra), so I’m just basically recycling it. It wouldn’t be a problem except that basement gets really humid in early summer and the dehumidifier really has to fight to keep up.

The long run and multiple bends would be a bigger concern for me. But, yeah... The electricity used to move water around the house and the $$$ it takes to keep it running is a shit sammich.
Another concern is the air cooling as it runs through the ducting, and then trying to push the heavier air up the unused chimney. That's a tough job for the fan, even a 6 inch fan. A second inline fan near the chimney would likely be in order to help move it all along, and then wiring that up would fun (well, *I* would enjoy that challenge).
Any other options?

If he has more than a 10 degree drop in his temp from tent to out and is moving air over 75% rh he will need a drain able p trap. That's right about dew point. It would sweat in the duct unless moving very fast.

Good call. I'll add that smooth-bore ducting will be a must... No flex!

I was worried about this too.
I doubt it would ever be over 75%, but it would sometimes be a 15 degree temperature drop, so 65% at 75 degrees flowing slowly through a flex pipe in a 60 degree room sounds like a setup for failure.
It would have to be flex.
I think I’ll have to rethink my setup. I know these plants drink up to a gallon a day each when full and healthy and I can’t have that going into the basement in summer though. Maybe moving the tent closer to the chimney could be an option, just not nearly as ideal.
Or there is a window nearby… hmmm…maybe, just maybe that’s crazy enough to work. I’ll have to shatter some glass though since the window doesn’t open. No biggie (I say while grabbing my baby beater.)

Sounds like the better option, if not the only option.

Okay… looks like I can exhaust out the window. Problem solved.
Moving on—> do these look a little too lime green? I think the issues on the first true leaves were caused by a ph issue, but I’ve got that under control. But should I increase nutes or light? They (especially the second photo) don’t seem a healthy green.
Whew! This hydro stuff really is fly by the seat of your pants, isn’t it?

Lime green on new growth until it gets enough clorophil converted for green green.

Friday update:
Plants seem to be doing well, so I changed the reservoirs with increased nutrients going by the chart I got from GWE. It’s basically the General Hydroponics Flora Trio recommendation, but at half strength. The plants had been soaking in a little less than the chart recommended, so hopefully the increase in nutes will guide them safely through puberty. I also increased the lights up to 300 umols, but I’m keeping an eye on some crinkly leaf edges.
Time is just whipping by this spring and I didn’t even realize they’re ten days old today. And there’s roots dangling in that there water. Yeehaw! I’m hoping for a July 14th harvest.
Tomorrow I’ll move the tent and route the exhaust vent out the winder.

Coming along! What's your water temp?

Water temp hovers right around 74. I’m using Hydroguard with every change.

Love the setup I also do dwc the little transfer pump works great there is a little Nutrient calculator from The Grow doctor and General Hydroponics

Thanks! This guy also seems to have a lot of other helpful information on DWC. I'll give his site a good going over as soon as I get a free minute. They're getting rare this time of year!

Day 14 update:
I think the plants are doing okay for two in. They seem to be growing kinda squat, which seems a good thing in a tent, but I plan to manifold and may need them to stretch out a bit more? The SF1000 led lights are reported to have a lot of blue and maybe that keeps the plants low if turned up too high. PPFD is only at 325 now.
They were really exploding in growth but the VPD was up around 1.5 with temps near 80, which was reportedly too high, so in hopes of even better health, I turned the heater off (it’s either on or off) and got VPD down to .9 at 68 degrees and growth just stopped. Did some finagling with exhaust fan speed and got it to around 1.2 at 77 degrees. Growth has refired back up. With that technique, I should be able handle temp and humidity to keep the required VPD all through flower. Fingers crossed!
Moved the tent yesterday and got the exhaust vented out of the basement. We also ran a new outlet with a gfci on it. Blazing new trails now—at least for me!
Wall needs a-painting!

A question slightly off topic: I have a single Northern Lights Auto seed free from RQS that I'm thinking of plopping in the ground. I live in the middle of dairy farms and corn fields and my gardens have always done great without any fertilizer, so I think the soil is decent, but of course it's hard to tell if it's right for weed. The ground around my house does drain very well, so I'm thinking of buying a bag of something, digging a hole, filling it, and then transplanting the plant into it once it gets going good and it's past the last frost date. My question is, what should I fill the hole with to minimize the amount of stuff I'll need to buy in the future? I'll of course take good care of the plant and watch out for pests, but I don't want to put a ton of money into it. I may be opening a bag of worm castings, but any recommendations?
