also, no idea on how to trim this mess lol almost gave myself a panic attack trying it earlier.

hah, also, small update. I think the timelapse may be done for lol. I'm venting my tent now, which is pushing my webcam out of optimal position. Plus the plants are getting a bit to big to see anything interesting:

I'm big on open source- really glad with this project ill be able to contribute upstream to another reputable project (pi4j). Plus... I know theres tons of great commercial options out there, like BlueLab. If somebody wants to pay money for a complete system, there's tons of options there. But...

Awesome! The atlas scientific stuff for pH was definitely the most expensive component, but the thing is amazingly rock solid. I was going to try and do my own analog circuit to run the probe, but after reading around I learned how big of a deal 'RF noise' is to the sensors, as well as direct...

Thanks! Oh, and don't forget the environment-controlled waffle maker, its clutch So I'm actually using the Atlas Scientific Tentacle Shield Mini with one of the Atlas pH control modules (I'll eventually get other modules, so sprung for the multi-component shield). I just did the I2C wiring to...

Thanks! I'm planning on open sourcing this thing sometime soon- I've got plans for another addition: basically a COB LED array/range hood with *another* pi lol. I wanted to showcase the remote nature/ability of the platform I'm writing, so having another example component that works on a remote...

Plants are looking big and bushy: Seeing some flowers start too: I'm being told this second one looks male, so... guess ill have to keep an eye on it

Yeah, definitely see more modern variants. As far as P, I've been doing a lot of research that seems to advise keeping P below 50ppm. Most plants are actually rather P hungry, and its arguably one of the largest limits on growth (P available, next to N availability). The main issue is that its...

Hopefully I'll be able to pull some of my own clones this grow, started with feminized seeds this time. Issue is I have 2 really big phenos, so not sure if ill have a chance to get good cuttings off the small ones. But it's alright, I guess those are the 2 phenos that took to the system the...

For the bacillus strains I was just planning (my *big* plan lol) on breeding in nutrient broth, then brewing an aerated 24hr tea with (minimal, almost trace) kelp/humics. Pretty sure I don't feel comfortable adding large amounts of nutrient agar/broth to my rez, so was thinking I could change...

My god. yeah im just not a good car person, anything more than an hour is like pulling teeth

1950s book from berkley, one of the first official publications on hydroponics. Also describes the the https://en.wikipedia.org/wiki/Hoagland_solution which... basically is just what all the nutrient solutions are today, some variation of it. also, i guess its 'nutriculture', not hydroponics...

another attempt at cloning. My first attempt failed, then i tried something different (erm, with rosemary) and it seemed to work ok so far. So, trying it again with some monster crop clones (2nd week of flowering, so maybe just regular). EDIT: these are now in an enclosed area to keep humidity...

Dehumidifier sorta works- seems to keep things at about 60-70% for me. The weather just got warm again, so im just gonna break the seal I think and start venting into the tent again. Updated picture- they're taking to flowering very well. I will never again grow different phenotypes in the same...

So I've actually already got a humidity sensor and unused relay hooked up to my (pi based) system. Was planning on it being lighting controls, heater, humidifier etc whatever I needed next lol. The issue I have right now is my damn tent is just.... packed. I bought one of those little amazon...

Yeah ive actually got a peltier cooler on the side of the rez, has been really nice and keeping the temps down during lights off- definitely not perfect tho lol. Right now the rez temps are at like 64, and the cooler only kicks on above 68. hoping things stay warm enough the next 6 weeks ive...

Damn sorry vanished from the forum a bit. So the last few days have shown 0 sign of root rot- my rez is also at about 65 deg right now, so probably miserable conditions for propagating anything. My pH is starting to normalize, so I think what I might have been seeing was actually a microbial...

seems one of the most popular micro mixes is "Peters Hydroponics Special"- has all the chelated micros, and a base mix (5-11-26 NPK, or 1-1-5 elemental). It's a good base mix, and a low enough on P (currently shooting for 3-1-4 elemental, 3-2-4 NPK). Also pretty cheap even at small levels, about...

really starting to sound like I should have just moved to colorado springs

trimmed em up a bit and switched over to HPS. It's getting REALLLY cold here right now, struggling to keep rez temps above 66. Finally get to use some full strength lighting though.
