Useful post for anyone who eats..
I've been learning a bit about aquaponics/hydroponics. I'm not planning to start a farm or anything, but it's always been interesting to me.
aquaponics - is usually a fish based system where fish are grown along side your plants in order to use their by products as nutrients for the plants.
hydroponics - is a similar system which doesn't include fish and the required nutrients are added manually to the system. (this is what this video covers)
hydroponics has long been used by pot growers because they often have to hide their crops inside houses so it's a bit nicer set up for indoors than dealing with soil inside a house. It also will allow for faster growing at higher yields.
Both of these types of growing are becoming more mainstream, especially with urban farming where they are dealing with limited space or are often growing in doors.
Anyway.. this video shows a extremely simple a cheap method that just about anyone could use to grow theirselves 2 head of lettuce a week if they choose. For the record you don't need the fish tank pump, there are no fish in the system so there really isn't a reason to add o2 to the water.
I randomly picked this guys video from youtube as the example because his hole design is set up for 8 holes which is the amount of space needed to grow 8 head of lettuce.
Basically, using a set up like this, you could start 2 new heads of lettuce per week and after roughly 30 days you would have a supply of 2 heads of lettuce a week as long as you keep the rotation going. (some varieties of lettuce will grow faster or slower)
Another vid that shows a guy growing with out the fish tank pump but also shows how to build a cheap light stand.
Anyway figured I'd show this simple way to grow yourself some fresh food very cheaply. You can grow other veggies as well.
