Thanks to Cornell’s Controlled Environment Agriculture program, you can learn optimal light, nutrient, and other conditions for growing lettuce and baby spinach (pdfs).
I’ve been able to find little to no other data like this. Pls let me know if you have!
Not something you’ll find in most stores, these grew in my raised beds in spite of substantial neglect.
But a nice little zen enjoyment for me, with a tiny greenhouse waterfall today:
More expensive, but a lot faster (and waterproof) than 3D printing each one…
Displaying data for ‘what plants need’ is an interesting challenge. I certainly haven’t figured it out, but here are some works-in-progress:
Check out this feed and source code on above pages to create your own!
Here’s full assembly for growerbot 1.5, in fast forward but at high-res and paus-able:
And, the latest source code is up on github. I’m excited to see what everyone’s building powered by growerbot!
Here are the Inventor files to modify my designs for the soil probe. I printed the 3d-printed parts directly from these. Enjoy, and please share any improvements you make!
I’m proud to announce Growerbot v1.5 has shipped to some patient, risk-tolerant testers!
Here’s a printable summary of the many new features (pdf). If you’d like a 3d-printed test unit, let me know and I’ll see what I can do!
Just got the dht22 temperature and humidity sensor working with the dev board for Texas Instrument’s new, <$10 wifi + microcontroller. Still early, but it’s looking like we’re gonna have quite power-efficient, meshable wifi on growerbot v2. Much more soon!
After *many* attempts, I’ve gotten the soil probe enclosure for growerbot v2 to where it’s 3d printable! There are 3 parts: the enclosure body, a press-fit lid that holds the solar panel, and the tip of the soil probe. i’ve successfully printed on both an ultimaker in pla and a lulzbot in abs; the abs should stand up to repeated use better. Here’s stls’s for you to print your own!
