I got my clones on the go now and I'm using Technoflora cloning gel. I heard the powder has a higher success rate? Hopefully I get 100% using this gel, as I want the same number I have now. (and did one clipping off each). I'm using rockwool; would you say I should start seeing roots in a...

I use a 68L Rubbermaid container per 1 4ft x 2ft flood table. The 8-channel relay will have VCC, 1, 2 , 3, 4, 5, 6, 7, 8, and GRND Vcc ---> 5V GRND --> GRND All the numbered ones just hook up to a free digital pin on the arduino. The SSR (Solid State Relay) will be used for your...

Here's some of the ethernet box's I'll be using for the sensors. They all connect back to the electrical / relay box via ethernet cables / jacks.

That puppy's huge, and much denser looking than I expected.

Yes, it's built into the Ardunio sketch. EDIT: It's based on this library: http://www.henningkarlsen.com/electronics/library.php?id=51 (which can be modified for quite a few different TFT LCDs)

You gotta save those pistils and bubblebag the shit out of 'em! Going to make some nice hash.

This is the wifi adapter I'll be using for my Raspberry Pi: www.ebay.ca/sch/i.html?_nkw=Edimax+EW-7811UN Edit: Here's a link for getting that working ---> http://wolfpaulus.com/journal/embedded/raspberrypi_wifi

I just ordered one of these: www.ebay.ca/sch/i.html?_nkw=Edimax+EW-7811UN

Hey dude. I would actually find a wifi adapter compatible with the raspberry pi. I can imagine trying to interface a wifi adapter/router with the arduino would be quite the headache. Might as well use the power of linux. You should be able to plug the adapter into the raspberry pi...

For completeness sake, this is the CO2 Sensor I already own. [http://www.ebay.com/itm/110888030682] I haven't tested it out and I'm not too sure it can give a percentage yet (might just detect [yes/no] )... But all this is to come shortly.

After many hours of research, I will most likely be getting this: http://webpages.charter.net/tdsmeter/products.html The submersible probe = $27 and the transmitter (just takes the input from the probe and outputs a range of 0 - 5V) for another $27... or an inline for $45... I will need...

I noticed I still had the ethernet shield on the sourceforge page; this is taken down now. I use the screen to control the settings. I have plans to make it so you can change the settings on the web page too though (so you can remotely change the settings). Make sure you get a SD card for...

I should be okay, I never thought to let the daylight in... and I was just freaking out a little when I heard they might be coming. Turns out they're probably going to stay at a friend's place. This is somehow relevant to Berk's encounters with maintenance. But none the less, I'll figure it...

Hey Art.... I actually am not using an ethernet shield at all and I bought a Raspberry Pi from element14. I using the Raspberry Pi to server the web page for info and remote control and to do the datalogging, but all the equipment is controlled via the arduino. There is USB to Serial...

Hey guys, I thought I could start my own thread, but I trust your guys' opinion, so I'll just ask here. I have a relative unexpectedly coming over for a night or two. I was just wondering how long I can shut off everything off for before my plants won't 'bounce' back? It's kind of one of...

I finally got my speed controller - so I'll wire it up this weekend :) Then I can start writing the PID loop for the Fan Speed based on the temperature. (Just going to keep switching between the circuit with the speed controller (adjustable) and full 120V)

Wow, I seemed to cause a big fuss (chiller - lol). Shittaw on the inspect! Good Luck.

I have updated the code for the Arduino standalone sketch and have included a Python script and a PHP webpage for controlling the Arduino remotely. This is now available at: https://sourceforge.net/projects/envirocontrol/ Note: I am using a Raspberry Pi as a web server for the Python script...

Canada = no chiller (for me anyways) :)
