Grow Tips for Success with LED Grow Lights

Use your G8LED grow lights properly for optimum growth and maximum yields. If you do not provide enough light, your plants will not grow to their full potential. Similarly, incorrect light placement will also not allow plants to grow to their full potential. Placing a light too close will stunt growth, too far will cause stretching. Follow the recommended coverage areas listed on the Details Page of each light for optimal light penetration and coverage. There are many variables to indoor growing with lighting being one of the most critical ones.

How far should LED Grow Lights be from Plants?

LED Grow Light Distance

As your plants grow and reach for the light, raise the light to keep the distance between the plants and light fairly constant. To grow plants taller, continue raising the light as the plants grow. The plants will reach and stretch towards the coveted light source. Stop raising the light when you do not want more length or when flowering. For shorter, bushier plants decrease the distance. If you keep the distance fixed, the plants will find an equilibrium height and grow wider and denser. Follow the recommended distances and adjust as necessary. The distance can be kept constant during flowering.

G8LED Flower Boosters 12-36inches

How Close Should LED Grow Light be to Seedlings?

The lights can be placed closer when growing from seeds. Hang the G8LED lights at the lower end of the distance ranges provided above. Once the seedling sprout and break ground, the light can be raised near the middle or higher end of the range. The G8LED lights will not burn your seedlings. However, if the light is too close to the new growth, it can discolor the leaves. If this happens, raise the light and let the plants adjust to the new distance. 

How Often Should I Water My Plants?

G8LED grow lights give off only 10% of the heat that an HID bulb emits such as metal halide (MH) or high-pressure sodium (HPS). The lower heat output also means there will be less water evaporation and less need for watering. If growing in soil, water your plants when the top half-inch of soil is dry (every 2-4 days) to avoid root rotting.

What Temperature Should My Grow Room Be?

G8LEDs have a lower heat output. It is easier to regulate grow room temperatures and the temperature immediately below the light. The ambient room temperature should be below 90 degrees Fahrenheit (ideally 82-85 degrees) and as low as 72 degrees when the lights are on. Temperatures will be lower during the off period when the lights are not in use.

How Much Rest Time Do Plants Need?

Although G8LED grow lights can be operated for 24hours per day, it is better to run the lights for 16-20 hours per day and give the plants time to rest.  Plants need dark time to more effectively photosynthesize light energy during light hours. Minimize working on the plants during the off-cycle and reduce light intrusion into the growing area during the rest time.

Vegetative Growth with LED Grow Lights

During the vegetative stage is when you will start to reap the benefits of your LED grow lights. During this period you will save on your electricity bills and get superior growing results if you properly follow the general tips listed in this section. In the vegetative stage, plants will start to show a healthy, deep green color.

Flowering with LED Grow Lights

Indoor grow lights can mimic the photoperiod of the seasons by the number of hours per day they are on. For flowering,  the light cycle will reduce from 18 hours to 12 hours per day. Give your plants 12 hours of uninterrupted darkness and 12 hours of light. Increased light in the red and far-red spectra of the visible portion of light, at the correct density and PAR metric, will increase flowering size and yield. Add G8LED  Flower Boosters at this stage for more robust flowering. With the C-Series lights, push the Flower Booster button to activate the magnification of the red, far-red, and hyper-red diodes.

How to Clone from Mother Plants

Any plant can be cloned, regardless of age or growth stage.  However, female mother plants in the vegetative stage of growth are the ideal choice for cloning. If the mother plant is in the flowering stage, the clones will require several weeks to revert to vegetative growth.  Proper usage of LED grow lights will multiply the number of plants you have in a methodical and environmentally friendly way. Mother plants should be at least two months old and should get 18 hours of light per day.
