Not entirely sure, I'll need to tear my setup down in the next few months (moving). Perhaps after the rebuild, assuming there is one.

I probably will set it up to measure out the Flora series GH nutes for an arbitrary volume of water. Edit: Grammar Maybe set up a special mix for topping off the reservoir.

I got the chemical pump from a commercial dishwasher for free today, woot.

Thanks for the quick reply Redtail! I dialed back the flood timer for that tray, I'll see if it improves :beer:

Whilst changing the water in my reservoir, I noticed some of the leaves on my Fatali plant were curling. This is what I found on the backside of the curled leaves. I beseech ye sages of pestilence, what is murdering my plant?

Out of curiosity, would any of you be interested in a kit version of the control board?

Tada!

The same thing happened with the plants I started in my Aerogarden 3 last year. I ended up taking the advice of the local hydroponic shop owner and cutting them apart with a razor blade. After transplant. 2 months after

I don't know of any books off of the top of my head. I'd start with an Arduino or a PICAXE and use the various communities and forums for each for a reference. I developed and etched the board with a common photographic process using a positive image from Eagle. Edit: Moved design files to GIT

The less sad version of the board, plus a serial LCD board crammed in at the bottom.

That stamp communicates with the MCU via a serial connection, accepting commands and is setup for 3 point calibration tests via serial commands. As far as keeping a desired pH value, I can use the same method the setup currently uses to set target temperature and relative humidity via a menu...

Thanks to lazy, I was able to start working on this again. He keeps saying I should build kits.. maybe. This is the prototype for the environmental controller portion, funded by lazy. It is setup to regulate temperature and RH in a grow tent. Far more switching power than what is needed...

Blast, I stupidly adjusted the angle of my grow bed without thinking & gave my 2 remaining plants root rot. Supid!!!
