How does drip irrigation work with cannabis?
Last updated Published
Watching the sun shine down onto your cannabis garden as butterflies roam the air and birds fill the summer air with melodies is surely a beautiful sight. But have you ever wondered, whilst gazing over your crop, if there is a more efficient and effective way of raising your weed?
Well, for a start, there is a very effective way to preserve water, deter weeds and keep nutrients closer to your plants' roots. Welcome to the world of drip irrigation.
Drip irrigation eliminates the need to drag a heavy and winding hose around your garden, that often ends up coiling around your legs much like an anaconda.
These systems use tubes, that run by the bottom of your plants, with outlets or drippers attached at certain points to deliver water to each plant. Water is pushed through these tubes at very low pressure, so as to only provide water one drip at a time.
This means, that your plants are receiving a constant, but tiny amount of water at a time. The rate of water distribution is extremely slow, depending on what is being watered. Water pressure can be controlled using equipment, such as timers and pressure regulators.
ADVANTAGES OF DRIP IRRIGATION
So why switch to drip irrigation? How it is any better then slamming on the sprinklers for firing up the hose for a while?
For one, it is far more efficient with water as a resource. Instead of shooting water all over the place and soaking areas of the garden, where it won’t go to optimum use, drip irrigation repeatedly and accurately keeps hitting an exact spot, meaning absolutely minimal water waste occurs.
Drip irrigation will save you the energy of wandering around the garden, making sure you have watered every plant adequately and will relieve you of the pressure of wondering if you missed any spots.
Utilising drip irrigation means, that barely any water is lost due to run-off, the little water, that is dispensed over time is fully absorbed by the soil and held in place. When the soil is blitzed by too much water, nutrients may be carried down deep into the soil and past the reach of the roots of your weed plants.
Drip irrigation may also result in faster growth because your weed plants demands for water are fully catered for and they won’t suffer from water stress.
Also, occurrences of mildew may be reduced, because the upper extremities of your plants, such as the leaves and stems, won’t be bombarded with water every time they are watered. Instead, drip irrigation hones in specifically on the soil.
More complex drip irrigation systems are composed of a pump unit, control head, main and submain lines, laterals and emitters or drippers. The pump unit is used to ensure that the correct amount of water enters the system to keep it at low pressure. The control head may use a filter to clean the system and also control pressure and discharge. Mainlines, submains and laterals dispense the water into the growing space. Emitters and drippers are placed onto the laterals and are placed above selected plants in order to provide water.
Easier alternatives for those starting out with drip irrigation can simply consist of two hoses with holes drilled into the appropriate places and some type of pump to control water pressure.
