A simple home growing system can be built very easily by someone without much mechanical ability
. A hydroponic system can be as simple as a jar with a single plant in it to a 5 gallon cooler an aquarium air bubbler, nutrients, and something to float the plants on like Styrofoam. You can even go as far as a complex water pump on a timer feeding nutrients to a container with plants arranged within. Really the hardest part of building you own system is getting over the fact that plants can grow without dirt.
First you need to pick a container that fits the plants you are growing. Dark colored plastics work best if you decide to go that route. It can be anything from a storage container to a juice bottle.
Next you need to mix the nutrient water. You need to know what nutrients the plants you are growing need and the best way to be sure is to consult a hydroponics specialist. You should use a 5 gallon bucket for the best mixing results as the residual nutrients will rest on the bottom and not over feed your plants.
Your plants will need sunlight. If you are not in an area where you get plentiful sunlight you should look into a red and blue lightwave LED. Certain plants have specific needs so looking into those before deciding is a good idea.
Depending on what you grow you will need to choose how long you allow them to culture and grow. Some plants mature quickly and others need more time. That said some plants flourish in a hydroponics system like tomatoes.
Hydroponics is a great way to grow plants without soil. It is also extremely efficient and in some cases will increase the yield of your crop. First and foremost you should figure out what it is that you want to grow because this will impact many of the factors used within your indoor grow system. Between nutrients, light, and growing time this is probably one of the most important things to know. An indoor grow system can be inexpensive if you choose to have one in your home, but countries like Japan are using similar techniques to grow lettuce and other vegetables in urban areas so that citizens that normally wouldnt get fresh veges are able and happy to have them available.
