Water is vital to life. Finding the right balance will help you grow a beautiful plant. There are plants that roots, grow and thrive when engulfed in water. Then there are plants wither and die when given too much water.
Cannabis needs water, but not too much and not too little. You want to find a balance between water and nutrients to promote root growth. The goal is to make the roots grow towards the water.
So, if you over water, then the roots will not become the big beautiful ball of an entangled mess that you want to achieve and the plant size will become stunted.
Before you water, check the saturation of the rockwool, or whichever media you choose. If it feels really wet, hold off on watering and put a fan blow at the base of the plants to help dry it out before you water again. This will give the root time to grow in search of water, making your plant big, beautiful and high yielding.
HID Lighting and Water
When growing indoors with HID (High Intensity Discharge) lights, which give off a lot of heat, you may think that you don’t have to worry about over watering. You always have to worry about over watering. Though you may have the heat from the lights, you may have too high of humidity, which can cause mold, attract bugs and stunt your root growth.
You should still have a dehumidifier and, of course, AC unit blasting cool air to counter the heat. The heat given off by the light will help the water to evaporate faster, but check you media to make sure that it is drying enough to make the roots chase down the water and flourish.
LED Lighting and Water
LED’s do not give off barely any heat. This means that a dehumidifier is a must. You will still need an AC if you live in an areas where summers get really hot. And really monitor your watering. Check you rockwool before you feed. Make sure that you plenty of fans circulating the air and blowing on the plans to help the rockwool dry out a bit so the root can spread and grow.
Air getting to the roots is so important. So, figure out a way to make sure that air is making it to the root system. Figure out how to ventilate your buckets. Growing indoors takes more attention and innovation than growing outdoors. Keep this in mind.
Signs of Over Watering
- Drooping plants
- Under developed root system
- Small weak plants
- Dry plants
My advice is to monitor your watering and make adjustments as needed the moment you sense there is a problem. You want your root system to penetrate through the rockwool and intertwine with the grow media. The root system should look like a big knotty ball. The bigger the root system the better, stronger and more yield you plant will have.
If you have your watering and feeding system on an automatic, still evaluate and check on your plants before the timer click on the system and when the timer click the system off. You never know what may happen and one error can cost you your entire crop and livelihood.
