The techniques you can use for making gardening far easier than it actually is are not that many and in most cases not that accessible in terms of costs or work put into getting it. In order to succeed, you have to think outside the box! This hydroponic system is that one clever way to grow plants on a small surface area with little effort. In the project featured on this webpage you can see how a homemade vertical A-frame hydroponic system can surely help you grow your garden plants. Actually, the hydroponic system is one great method for growing herbs or other small plants, like radishes, lettuces or strawberries; for the last type it is way more attractive because you won’t have to stand on your knees and on the ground, but just pick them while standing up. View the following video tutorial in order to make a working hydroponic system. Start growing 168 plants on a 6 by 10 surface!
