Carbon filters are used by indoor gardeners to purify the air entering and exiting their indoor gardens. Carbon filters can remove pollens, bugs, molds, pathogens and unpleasant odors from the air. Join us as we take a peek inside your carbon filter to see what’s really going on!
The Ebb and Flow hydroponics system is a very popular method among first time hydroponicists. It uses a submersible pump in a nutrient reservoir to pump nutrients into an upper tray containing the plants. The pump is switched on several times a day via a basic timer. The nutrient solution is pumped up to the [...]
Everest casts his critical eye over blueprints of real indoor gardens and examines pros and cons with their designers. Under the spotlight this time is Claude. He’s built what he calls an “almost sealed” room to produce heirloom tomatoes all year round. Will his set-up produce juicy fruits of joy or paltry piles of passatta?
