Thermal grow tent

Here it is folks, an inside look at my thermal grow tent. Again hippies you can see no license required. That is a golden zucchini in the foreground and a tomato in the back. The plants are in pots that are sitting on a 6 ft by 2 ft by 2ft box filled with river rocks. In the background is a dryer duct that allows fans installed in the box to suck hot air during the day from the top of tent and the blow the air throw the river rocks back up into the tent.

No need to go to the gym on the day I shoveled all those rocks.

Inside the box there are two .25 amp 12vdc computer fans that as of yesterday are running on solar power. During the day, the rocks cool the air (and themselves warm up) that is forced through them. At night, the rocks help keep the plants warmer. Before the solar hook up, I had a an extension cord and a 12vdc transformer running the fans 24-7. Not sure if the plants get colder at night now since the plants are only being heated passively at night without the fans since no solar. May have to add a 12 vdc battery. Next post, some photos of the solar panel.
