How do I grow basil hydroponically?

First, you will need a system to grow your plants. This could be as simple as a shallow plastic tray or it could be a more elaborate system using a reservoir. If you plan on growing large quantities of plants, you'll want to buy a system that's made for commercial use, since these systems have been engineered for high production.

You'll need to do is measure the area where you'll be growing your herbs. The next step is to decide if you want to grow them indoors or outdoors.

If you're growing them indoors, you'll want to figure out how much space you have available. You'll need to purchase an inexpensive light fixture and set it up. You can purchase a small greenhouse that is made specifically for growing hydroponically, but it can cost as much as $

If you're growing your herbs in an outdoor garden, you will need to determine what size garden you need. Most garden centers will have information on how much square footage you need to grow your herbs, and you can use this to figure out how big your garden should be. Once you know how much space you have available, you can begin planning your hydroponic system.

You can purchase a tray system or you can build your own. In either case, you'll need to decide if you want to go with a shallow plastic tray or a reservoir. The most common type of system is the shallow tray system, which consists of a tray and a pump. The tray is filled with a solution and placed in the location where the plants will be growing.

The nutrients are added directly to the tray as needed. With a shallow tray system, you'll need to refill the tray periodically so that you don't run out of nutrients. Some growers recommend adding a small amount of fertilizer every day. Others use the same nutrient solution for a week or more, and then change it out every two weeks. You'll also need to monitor the pH of the solution, since it should be between 3.5 and 4. If the pH becomes too low, your plants won't be able to utilize the nutrients properly. You'll need to add an acidifier to keep the pH balanced.

Once you've determined how you'll grow your herbs, you'll need to figure out what type of nutrients you want to use. You have several options, including organic fertilizers, compost, and manure. The most common nutrient solution is a 1:1 mixture of fish emulsion and water. You can add other ingredients, such as seaweed and kelp, to the solution to boost the nutritional value. The amount of fertilizer you add will depend on how much light the plants receive. Some growers recommend adding as little as one teaspoon of fertilizer per gallon of solution. Other growers add as much as 2 teaspoons per gallon. If you're growing your herbs in an outdoor garden, you may want to use compost instead of fish emulsion. Compost is made up of plant materials that have decomposed naturally, so it contains nutrients that your plants can use.

What are some other concerns?

If you live in a very humid area, you will need to make sure your nutrients don't dry out. You'll also want to provide a place for the excess water to drain off, so that the solution won't get too saturated.
