How to DIY your Ebb and Flow System For Growing Cannabis -2020

WHY HYDROPONICS?


While growing your cannabis hydroponically may be a bit more difficult in some respects, it can certainly be rewarding. If grown correctly, hydro plants typically produce higher yields than those grown in soil.



Moreover, fewer resources are required to grow hydroponic plants successfully. This is because hydroponic systems deliver nutrients to your plants much more efficiently than soil. As such, you should expect your plants to not only grow faster, but also bigger. The streamlined nutrient delivery of hydro setups is usually expected to result in 20–30% higher yield come harvest.



Hydroponic systems tend to reuse resources as well. By using the same water over and over, they will cut down on the amount needed over the lifetime of the plant. Additionally, hydroponic growing is much more efficient. By just regularly checking lighting, ventilation, water, pH, and nutrient levels, you can ensure your plants will keep growing with minimal fuss.Additionally, hydroponic systems tend to do a better job of protecting plants from threats such as pests and diseases. This is because hydro systems are sealed, closed off, and less susceptible to invading threats. Cannabis is especially known for its sensitivity to impurities in the soil. As such, growing cannabis hydroponically can be a much more reliable and less frustrating experience than growing in soil.



Ebb and flow systems are effective and very versatile, being able to accommodate a variety of plants, of different sizes and in different sized pots, with great ease.Ebb and flow systems are a good choice for beginners and advanced hydroponic growers alike. They require a rudimentary level of technical knowledge and are some of the most productive systems available.

  • Aeroponics - This is the process of growing marijuana in an air or mist environment however without using soil or any kind of medium.



  • Continuous flow – Continuous flow techniques include NFT and Drip systems. The basic concept is a continuous flow of nutrients with good drainage and flow.



  • Deep Water Culture (DWC) + Recirculating direct water culture systems (also known as RDWC) + BubblePonics.



  • Drip Irrigation – Also known as trickle, micro or local irrigation. Uses small emitters to drip nutrients directly onto the roots or soil of your plants. Saves water and nutrients, can be used with mediums and soil.



  • Ebb and Flow – Or Flood and Drain hydroponics is simply a method to flood your pots with a nutrient solution at regular intervals and then let it drain back into the reservoir.



  • Nutrient Film Technique (NFT) – Nutrients are pumped from the reservoir into a tray to form a thin film of nutrients constantly flowing with the roots of your marijuana plants dipped in them. There is no growing medium.



  • Wick system – One of the most basic systems to use, if you are just starting out and want to get going today, try this.


EBB AND FLOW


Ebb and Flow. Also called Flood and Drain uses gravity to return the water to the reservoir to reprocess. You only need a reservoir, flood tray and submersible pump with timer. This hydroponic system regularly soaks and drain the root of the plants. Water won’t become stagnant, and the root will get plenty of air. Clay pellets or lava rock are the best medium for this hydroponic system because it drains well while retaining some moisture . You can also use vermiculite and perlite mix cause it also works well with root vegetables. PROS Easy to learn Helps avoid root rot Low cost CONS pH of the nutrient has a chance to fluctuate which is unhealthy for the plant Roots are prone to grow together so it may damage other roots when harvesting Higher maintenance due to periodic renewal of water and nutrients


DIY – Your own Ebb and Flow system


There are many excellent ebb and flow systems available to buy on the commercial market. These systems generally offer excellent value for money and have proven effective and easy to use.Other systems sometimes use ebb and flow as part of multiple SuperPonics systems, such as these upwelling Bubble Flow Buckets from Dealzer.However, us growers are normally resourceful, ingenious and adaptable creatures and we know that many of you will already be thinking about how you can construct your own.Building your own ebb and flow system is easily achievable by anybody with a rudimentary grasp of do it yourself skills. Once you understand the concept it is simply a question of arranging all the components in a way that works and fits in with your own requirements.You will require: Reservoir with strong lid, a sturdy tote does the job; Plant tray (flood tray) that sits securely on top of the lid; Water pump (a garden pond pump is ideal); 2 fill and drain fittings, available from hydro suppliers or DIY/garden stores; Extension piece to create overflow; Length of ½” black tubing;Once you have all the components together, you need to assemble them so that the water pump can fill the reservoir and then drain off afterwards. You also need an overflow system to prevent spillages. Make two holes in the centre of the base of the flood tray; Make corresponding holes in exactly the same position in the reservoir lid; Align the holes in the plant tray and reservoir lid and join them together by fitting both the fill and drain fittings to the holes; Attach one end of the black tubing to the water pump and the other end to one of the drain holes beneath the lid/flood tray assembly; Attach the overflow extension to the top of the other fill and drain fitting; Fill the reservoir with nutrient solution and position the water pump under the water by fitting the lid/flood tray assembly; Place your plants, in pots, in the flood tray; Set you timer accordingly.When the pump runs the flood tray will fill with nutrient solution. The overflow pipe governs the depth of solution and will prevent the flood tray from overflowing.When the pump switches off, the nutrient solution flows back into the reservoir via the drain hole.
