This system design truly is almost worry free. The secret is allowing plenty of room for water storage, so the system will never overflow and the fish tank area will never run low on water. Follow along through this instruction and you will also have a worry free aquaponics system of your own, and the best part is that this isn't difficult at all to build, but every piece in this system has a special purpose to keep everything in a happy balance. Benefits of aquaponics systems include: - Low set-up costs - Less water used - only 2% of conventional gardening, so ideal for hotter climates where drought can be a real problem - No need for fertilizers, pesticides or herbicides - No waste to get rid of as it is all used within the system - No need for fertile soil - Up to 4 times more produce and much quicker growing times, means you can harvest more for longer Aquaponics is a method of growing plants, like marijuana, in a soilless medium. Plants, fish and beneficial bacteria work together to create nutrient-rich water that is constantly flooding and draining in a grow tank. Gravel, coconut coir, lava rocks, rockwool and many other kinds of soil substitutes can be used to grow a plant in an aquaponics grow system. The plant receives nourishment at the root and grows more healthily than with soil gardening.
