I am (Very much theoretically) wondering, given that chlorophyll has quite a tight absorption spectra could you use a solar panel to power an LED array that just outputs blue and red light and get more/better plants per square meter than using that square meter of sunlight. (Taking into account the significant losses in the system etc.)
I'm working on a story where some people live in a cave and have to grow their own food inside. I would like some idea of what could realistically be grown in this situation (more details below). [more inside]
Any indoor gardeners or hydroponic fans out there today who could help me out? [more inside]
I'm thinking about starting an indoor hydroponic garden soon, using a guide I found on Instructables for DWC. What are some good vegetables/fruits to grow beyond tomatoes and herbs, which would ideally grow at similar temperatures and light levels as tomatoes and herbs? And what's the best place to buy seeds, either online or in the Princeton/New Brunswick, NJ area? [more inside]
What are the not-so-obvious problems that may occur if a major city replaced dying schools/golf courses/churches with multi-leveled solar/geothermal powered hydroponic vertical farms? [more inside]
AskingForANovelFilter: Which would be easier and more economic to grow in a domed colony on Titan or to import from Earth: coffee or tea? [more inside]
How do I build a basement vegetable garden in winter? I have gardened over spring/summer/fall outdoors. I need advice on what lights to buy, what vegetables can grow over winter, how to pollinate, etc. Also, can I use heat lamps to help with the warmth loving vegetables, or is that too energy inefficient?
I live in an efficiency, and am thinking of getting an aerogarden to grow fresh vegetables and herbs. I hear they work well when it comes to growing, but I'm wondering how things taste in comparison with stuff from the supermarket.
What sort of methods do authorities use for detecting small to middle size indoor marijuana crops (e.g. hydroponics)? [more inside]
At some trade show recently, Whirlpool showed a prototype washer called BioLogic that ("if feasible") relies on hydroponic plants to purify and reuse the water [pdf, p17]. So, are there any users out there who go to Kitchen and Bath trade shows, and know more details about how this works? Alternate question for hydroponics enthusiasts: What kind of plants are those in the washer?
