what are you dipping em in? just liquid root hormone?

good call! yea my biggest theory right now is that exposing the inner layers is definitely the biggest factor in getting the root development, the great white I think mostly just acts as protective layer while the tissues begins to grow and heal- plus getting some really early mych inoculation

Just a small update here. Still cloning this way, and it's still working.... really well lol I've gotten even lazier with it, the water in this cloner hasn't been changed in.... over 5 months now. These clones have been in there 7 days, 100% and super healthy.

lol just realized i totally forgot to update this with the outcome. I got about 5 ozs in the end, plus an oz of larf and stuff i didn't want to bother trimming. Part #3 is coming up, as soon as i can make up my mind which genetics to go with. Might try to pop these headband bag seeds

lol yea, sorry my last post sounded a bit too grim. appreciate the love, and also knowing im not the only one to have shattered that stuff like glass.

The RPi was a good choice for me because I knew I wanted to run linux. But if you're not picky about that stuff, the arduino is definitely the way to go. They're both very capable machines for sure. But it's definitely a small linux computer- it's kind of a big jump in complexity As far as...

so, one thing I just added here was a 100k potentiometer as the resistor that goes across (parallel) the DIM leads. I've tested it all finally, and combining PWM and resistance based dimming definitely works together as you would expect. I measured the wall wattage, and its mostly linear as...

Thanks! Yea lol it's done on the cheap and easy for sure... It was hard to hear "dorm room setup", cause I quickly realized that that's.... literally about how much space and budget I have to work with, plus an outdoor closet for growing. :( The house in the mountains is definitely in the near...

https://www.rollitup.org/t/diy-steady-state-cxb3590-build-w-raspberry-pi.934250/ Bunch of pics and some other tech details. But damn, it definitely works! Yeah, at least the CPU fans I've seen never go completely off. I feel like its an extra safety feature so you dont fry your CPU. It's...

Alright guys, I've been picking away at this damn build for almost 5 months now. I have finally have it up and running, software and everything. So this is basically a cheap automated DIY 4x CXB3590 system, driving at 1050mA. Goals * Steady-state operation within specified thermal bounds *...

yesss, i finally have everything working perfectly. automated fan speed and dimming. writing a new post now

also, I really have to say that I'm loving these intel coolers for this project so far. They give almost perfect clearance for the holder brackets, about $10 each, rated at up to TDP 65W. Also hilariously easy to control with a rpi or other single board computers. Only issue is no holes for the...

I did find one of these awesome relays (now that I know I have to use the AC input, good call @xX_BHMC_Xx): https://www.adafruit.com/products/268 Just an inline AC 'cable' with a relay in the middle. I trust myself wiring AC as far as I can throw... myself.

yep, LGTM. Are you putting the relay on the power OUT from the driver, or the AC power in? I'm probably going to do the relay on the power OUT from the driver, not sure if there's any big difference. EDIT: ooh, wait, i just saw the relay is in line with the PWM... that might cause some issues...

Yea the biggest mind-fuck for me was realizing that the DIM relied on a voltage of 0-10V, its kind of an odd way to look at it. But really it's a 0.1mA source that expects a resistance of 0-100. Put a 100kOhm resistor in parallel with the dimmer. This sets the default path of 100%=10V. Not...

I settled on this schematic for the dimmer with my raspberry pi. The dimmer is on the right, represented as a 0.1mA constant current source. Also uses 2 NPNs to fix the inversion, but thats totally optional. I might ditch it just so I have less parts on the bread board. Haven't tested the...

I decided to go the transistor route cause I was getting confused by the optocoupler datasheet lol. You shouldnt need the voltage regulator either, I dont think. The DIM controller is actually a constant current device (0.1mA), so the resistance actually sets the voltage. So if you have an...

optocoupler seems to be the preferred way- plus no inversion. Just a matter of finding whatever resistors you need

Awesome! Excited to see how it works out for you. So with the GW and rooting powder, I actually mixed it dry and just applied it to the damp stem. Also once cutting up the tissue, the stem seems to 'leak' some juices which join the mix. Using the compost tea, I'd maybe just mix a little bit...

Sulfuric and nitric acid should be the best when dealing with tap (nitric a little better). The plants can deal with sulfates/sulfides pretty easy, but nitrates antagonize (solubility/availability) Mg and Ca far less. Switching to sulfuric acid fixed almost all of my pH bounce-up issues. Once I...
