Oh sweet, I'll check that out. I just gravitated towards Arduino for some reason when I first picked it up.

The whole thing is like 6'8" but the upper grow space is about 42", lower 22". Front access is nice, but I put my net a bit low and it's pretty fuckin hard to water right now. Might setup a drip system soon.

Nah I don't mind. One of the reasons I didn't start a "grow journal" was the no posting policy. That inkbird looks like a pretty slick little setup. I want full control of the lights, fans, humidifiers, and watering, plus data-logging and wifi... so arduino/rpi is really the only way to go lol

Oh wow; haven't checked your thread yet, apologies. I'll have to look into it more, thanks for the heads-up!

Interesting, but I think the bacteria/microbes in the soil are probably much more sensitive to chlorine than a dog. I just wouldn't want to take a chance on it when all you have to do is wait a bit longer to be sure.

Patience is key, take your time in the design phase. The more potential problems you can address before spending any cash, the less painful your mistakes will be lol

Wuuuuutt? That's pretty quick! Source? I just fill up my 5 gal res when it gets low after watering, then it sits for a couple days anyway until the next use.

Thanks man, I'm glad I can give back to the community in some way. As for the pantry, ddooooo iiiiitttttt... :bigjoint: I'll be converting the lower section to a veg area for a semi-perpetual soon. And maybe full control of the whole cab via Arduino... stay tuned!

Cup score for the next run: Now we wait... :fire::fire::fire:

Interesting, I'll try that out. Do you let the chlorine evaporate for a day or so first?

PH seems to be okay. I'm using the GH drops, so I have to eyeball it, but I try to keep it right about 6.5. After letting the chlorine evap from my tap water PH gets up to like 8, it's insane. Using like 1ml/gal of PH down to get it right.

I haven't been foliar feeding anything. I'll definitely play around with some different options next run. Any suggestions? I've got plenty of airflow, just blocking lots of light to the lower nodes. Am I good to pull these massive fans at the base of each branch?

Thanks. Yeah I took a few big fans at once from each lady when they were pretty small, and they took a while to get over it. I'll probably start pulling a couple here and there.

If you really want to DIY, Loki_grow on IG made a DIY chiller for his DWC system. Might be able to get some inspiration there.

Day 42: She's really starting to fill out, lots of new bud sites pushing through the canopy; she seems to be enjoying the extra room! I noticed a recovery period of slow growth after I did the last round of defoliation, and I'm already a bit behind where I wanted to be, so I haven't done...

Of course man, that's why we're all here. You should start a thread in the LED section for your questions though, you'll get more than just me answering there.

Nah man, you didn't. Reread your post. Wish you all the best with your build though!

Your layout sounds fine. Determine how hard you want to run your chips, then pick the driver that fits best. Run your chips in series on a constant current driver, or parallel on a constant voltage driver. If you're running series, just make sure your total voltage drop for all cobs is less...

You could run into an issue if say, you had a fan blowing across the heat sinks of one string and not the other. This would cause one string to run at a slightly different voltage, and could lead to a thermal issue. If you can make sure they all run at the same temp, you should be okay. I...

You'll need a 100k ohm pot to get full power from the driver, plus a 10k ohm resistor to keep from going below the recommended 10% minimum. Or get a 50k ohm resistor for your current setup, but then you could only dim 60-100%.
