What is DIY hydroponics? It's a gardening process that enables you to grow plants, crops, vegetables, and more, all whilst not having soil. This is a especially productive approach for zones where it's too warm, too arid or too bumpy to plant whatever. There are lots of advantages that hydroponic gardening gives you over land based seeding - the most significant ones being that you will no longer need to stress about weeding, invasive plants, or pesticides, due to the fact that all of these can be found within the soil.
