Yesterday I installed a new automation system for the DWC hydro box:   I've installed two Duckbill water level sensors. The upper one is for the automatic filling of my hydro box, by Arduino. The lower one is for the pump control, in case the pH is out of range or if the water temperature...

I really like your good advices guys. Especially the 360 degrees sprayer. Personally I think that the dwc concept is mainly on slow moving water. But I am not sure about the definition. After 4 weeks of cultivation, this is the current status:     Rainforrest:   Aji:   Hurricane:   El Jefe...

Hi all, Here an update from the Netherlands. Last year I started an experiment with growing cuttings from a Jalapeno pepper on water. To my supprise after a few weeks roots were growing and my plant was developing. My attention was triggered:       Therefore I started this year with (for me) a...

Good luck all of you guys! Let the best win. Last year we had in Holland a similar growcontest, organized by the Dutch chilli pepper forum. http://www.chillipeper.nl/forum/viewtopic.php?t=988 The winner reached 3.02 m, my Brazilian Starfish reached 2.82 m, good for the second place :-)

I'm not necessarily interested in even making it self watering but if I could check my pH and temp and ppm of my hydro resovoirs from my phone, it would make things a lot more convenient I think that's even more difficult than self-watering but that is still possible. You'll need similar...

This is awesome! I notice that most of you have technical backgrounds.... would this be impossible for somebody with 0 knowledge of writing code? Everything is possible wright? It requires probably more (learning) hours, but everyone can build his own project. That's the purpose of Arduino of...

A happy and healthy 2014 for everyone! Greetings from the Netherlands

I actually tried to purchase one of the really cheap probes from Hong Kong for around $7 US, but after a few days the company emailed me and said that they needed to refund me the money because they were out of stock... Funny how they still had a listing saying 18 "in stock" but the price had...

  Right! When considering 80 liter, a 1 ml dosing is recommended (I use liquid HNO3- 38% acid)   I think Atlas is good enough for our purpose. I'll always search on Ebay for cheap sensors, maybe not as reliable as Atlas, but much cheaper (I'm a hobbyist ;-) ).   You search on Ebay for pH bnc...

Growing and creating....

  Great!!! I wasn't aware of the fact that you've already noticed the HAPI site and "my tutorial (which is very simplified when I'm considering my code and wiring now...)   You can use the DS18B20 temperature sensor to measure your water temperature!!! It's a really great sensor for that!   When...

Hi Brian.   Very nice project. I'm almost doing the same, or trying the same.  :party:   Together with a Belgium pepper grower, who's also very interested about home automation techniques, I started an Arduino based project to automatically irrigate my pepper plants by a soil moisture sensor. If...
