Growing Tips for Indoor LED Grow Lighting

Now that you have your LED grow light, you must use it properly for optimum growth and yield. The biggest mistakes people make with LEDs are not having enough light and not placing the light at the proper distance. If you do not provide your working space with enough light coverage, you can expect but robust growth. Similarly, incorrect light placement will not have optimal results. Placing a light too close will stunt growth, too far will cause stretching.  Keep in mind that there are several variables to indoor growing, so you could need to add or remove some light counting on your own specifics.

Keeping the proper distance between your led grow lights and your plants is very important to robust photosynthesis and growth. Your LED grow light provides the wavelengths of light your plants would like for growth and flowering. LED grow lights are formulated to the Photosynthetic Activation Radiation (PAR) wavelengths necessary for plant growth. Plants will reach for the much in demand light source just like they grow towards the sun in outdoor conditions. The general rule of thumb is to increase the distance between the highest of the plants’ canopy and also the light source because the light becomes more intense. This means that hydroponic led grow lights different power ratings can perform best at different distances. The 240 Watt LED Grow Light ought to be 16-30 inches from the top of the cover. Larger lights such as the 450 Watt LED Grow light ought to be lowered around 20-30 inches from the top of the cover. More intense lights such as the 600 Watt led Grow light shold be kept at 24-26 inhes & the 900 Watt led Grow light ought to be unbroken 26-42 inches from the top of the cover of your plants.

Since LEDs do not emit large amount of heat like MH/HPS systems, you can higher regulate the area temperature and also the temperature immediately below your light. Ambient room temperature may be 82 degrees instead of 72 degrees during lighting and can go as low as 60-65 degrees once the lights are out. Be sure to use less water than you’d ordinarily use as led lights emit much less heat than conventional methods. Wait until your soil is a bit dry before watering once more. You should also use 30 minutes less nutrients as compared with MH/HPS once growing with LEDs

Do not add your grow room once it’s supposed to be dark within the OFF cycle. The plants need the dark time to rest and light intrusion can negatively have an effect on their growth. If you must work during the OFF cycle, use green light bulbs for lighting as the green light is reflected by the plants and will not disrupt their sleep schedule.

Vegetative State
During the vegetative state is once you can begin to reap the advantages of your crystal rectifier grow lights. During this period you’ll save on your electricity bills and obtain superior growing results if you properly follow the final tips listed during this section. In the vegetative stage, plants need less intense lighting than in the flowering stage.

Vegetative growth is maintained with 16 or a lot of hours of light. You can even keep the plants below 24 hours of light and that they can still grow during this stage. However, the recommended growth cycle is 18 hours of light throughout the vegetative growth stage. This light cycle can produce an enviornment that mimics the photoperiod in the summer with long days. During the vegetative stage is once you can begin to reap the benefits of your crystal rectifier grow lights. During this period you’ll save on your electricity bills and obtain superior growing results. In the vegetative stage, plants need less intense lighting than in the flowering stage. It is during the vegetative growth stage that biological research, transplanting, pruning, and bending are all initiated.

Turn your LED grow light ON for 18 hours a day so turn the light OFF and leave your plant within the dark for another 6 hours. Your plant will would like four to six weeks of this cycle to be able to begin the flowering stage. Pre-flowers are the first indication that the plant is prepared to move into the next stage of growth. The pre-flowers grow at branch internodes just behind the leaf spur in around the fourth week of vegetative growth, when the plant is six to eight weeks recent. When you begin seeing pre-flowers forming this implies that the plants are ready to get into the flowering stage. You can still grow within the vegetative growth stage or switch to flowering at this point. The pre-flower looks like a regular female flower with white fuzzy pistils. The pre-flowering can take from one to 2 weeks. Wait to induce flowering until pre-flowers have appeared. Induce flowering by switching your light cycle to twelve hours of uninterupted darkness and 12 hours of light.



With LED grow lights we mimic the seasons by changing the light cycle from 18 hours a day to 12 hours. Give your plants 12 hours of uninterrupted darkness and 12 hours of light to induce visible signs of flowering in fortnight or less. Adding more light to the plants additionally facilitate give bigger flowers and yield. It is recommended to add an all red LED grow light at this stage for additional strong flowering.

Once you have induced flowering for one to two weeks and flowering starts, it will last can last eight weeks or longer. During flowering growth patterns and chemistry changes in the plants (i.e. indoor growing flowering stages). Stems elongate, leaves grow progressively fewer blades and flower formation is rapid at initial then slows. Phosphorus and potassim uptake increase to promote floral fomation. Your nutrients should have less nitrogen and more potassium and phosphorus during flowering. Don’t give nutrients too often as this will cause your plant to induce nutrient burned. You should use about 30 minutes less nutrients with LED flowering grow lights as compared to MH/HPS systems. Do not overwater, over nutrient and do not harvest too early.


LED grow lights are great for cloning plants. Proper usage of LED grow lights can multiply the number of plants you have got during a methodical and environmentally friendly method. Cloning need solely 2-3 weeks in the vegetative state. Use an 18-20 hour ON cycle for your clone and spray it with water intermittently. As with the vegetative state, when your plants are seedlings the light should be at the recommended hanging distance. As the plants start to grow modify the light upwards a few inches at a time.

Protect Your LED Grow Lights

Buying a LED grow light is a capital investment for your indoor growing hobby or business. The investment offsets other capital expenditures by eliminating the need for ballasts, reflectors, heat venting systems and airconditioning in addition to lowering operational prices by dramatically decreasing the electricity consumption of your grow room. To protect your investment you must connect your LED grow light to a power stabilizer. The power stabilizer will regulate the voltage coming back from your power box and eliminate varied power fluctuations which may damage devices. If too many high wattage devices are connected to the same circuit there may be voltage fluctuations which harm power drivers inside the LED lights that power the diodes. This is very true for growers who use solar energy to power their grow rooms since these systems tend to possess power spikes and surges. Power stabilizer are cheap and are a nice investment to shield your lights and plants, to ensure there’s no down time during critical stages of growth.
