Greenhouse:
Greenhouse is keeping the temperature higher than the normal air. The raspberry pi has been consistently reporting higher temperatures on the inside of the greenhouse compared to the outside. It is keeping the temperature at the high 80s in the middle of the day and mid 70s at night.
Check the twitter account to see what it is currently! Be sure to retweet or favorite a tweet! It is always helpful to me to know that people out there are seeing the Pi on twitter. (@rpiph1)
The plants have been growing very well in the warm temperatures. After about 3 months from planting (see the previous blog post) the plants were very lush and dense. Four months after to have to trim back the plants so that they don't hit the light. Additionally I have my first flowers on the pepper plants opening up and lots of plants developing flower buds!
The best plants for hydroponics:
The bell peppers and hot peppers are growing really well.
The basil is doing really well.
The tomato plants grow but I think I need a bigger space for them to actually fruit.
Green onions and garlic grow well.

The Raspberry Pi:
The raspberry pi has been tweeting uninterrupted for months using the code I published in the October 18th, 2015 blog post. (the one right before this one) The temperature sensors have been accurate and reliable for months. Nothing new to report here.
Hydroponic Systems:
The water pump (running 24/7), box of hydroton grow rocks, tubing, and coarse screen for filtering is all working well. No leaks to report. I add more water to the reservoir every few weeks.
