Hydroponics Made Easy

There is more to successfully growing plants indoors than simply bringing them in from outside. Using grow tents or grow rooms to provide controlled environments will allow you to grow plants that are usually hard to grow. They will allow for more yield or more crops when plants are grown indoors.

All plants need a positive environment and proper nutrition if you want them to thrive. Growing without soil is one way to use sterile media to control everything that will go into your crop. You’ll need to be especially vigilant in keeping quality nutrients administered, since the plants won’t have another way to get their nutrition.

The proper climate and temperature are vitally important for hydroponics. When you are in a cycle where your plant lights are on, the temperature should be between 70 & 80 degrees F. When the lights are off, the temperature should be between 64 & 71 degrees F. The ideal daytime growing temperature without augmenting CO2 is about 73 degrees F. If you augment CO2, the ideal day temperature is 76 degrees F.

The roots need a specific temperature to thrive, as well. Keeping your plants at 68 degrees F will benefit them, as will keeping the temperature of the water and nutrient solution between 66 and 71 degrees F.

The humidity in your grow room or tent should be maintained ay 40-65% when plants are in their vegetative phase. During times of flowering, 40-60% humidity is most beneficial. If you allow the humidity to get too high, you may have to battle mold or other harmful organisms.

Grow lights for vegetative growth should be on for 18 hours and off for six hours. Leaving your lights on all the time has not been shown to increase growth rates. If your plants are flowering, 12 hours on and then 12 hours off will work, although this can vary, depending on what plants you are growing.

There are various types of lighting that are beneficial for different growth stages in indoor grow rooms or grow tents. If you’re cloning plants or have early cuttings, fluorescent lights work well. During the growth cycle, High pressure Sodium or Metal Halide lights will work the best. During the vegetative growth state, you may wish to use 60% Halide light and 40% HPS. In lighting floral plants, use HPS lights only.

For your sterile growth media, you may opt to use processed coconut husks, rockwool, vermiculite, lava rocks, perlite, coco coir or clay pellets. Your plants also need a lot of oxygen, particularly in their root zone. A hydroponics system will give you the maximum oxygen in your root zone, which will allow your plants to grow faster.

Plants need a lot of CO2 in the underside of leafy areas, and the total grow room CO2 should be about 1500 ppm. You may have to augment CO2 levels, especially if your temperatures are above average.

You should circulate air in your grow room by one or more medium fans, even if you only have a small grow space. In addition, exhaust fans should be able to exchange all the air in your grow tent each five minute span. Be sure to time them so that they don’t pull out CO2 that you are augmenting.
