Today I am going to tell you something about my experience with LED lighting technology in my indoor marijuana crop
First, to say that I started growing under LED a few years ago, and then, I have been experimenting with different LED models in my growing cabinet, also seeing the technical advances that, little by Little, the commercial brands have been incorporating in their catalogues.

Why did I choose LED lamps?
Above all, to minimize the costs of the electric bill, being a more ecological way to enlight your crop, mainly because it scarcely dissipates energy in the form of heat, avoiding most water loss by transpiration, and saving on electrical consumption used for the climate conditioning in the indoor crop, which also leads to a great saving in water and fertilizers.
By the way, indoor LED growing lamps have evolved a lot in recent years; the first panels were very heavy, had very noisy ventilation systems and employed a lot of watts of consumption.
Today, you can buy several types of LED panels at a more than affordable price, although I will tell you about for me are the most useful, and have given me the best results, such as Phytoled GX400 panel with full spectrum for the whole cycle, either for the growth and flowering stage.
LED panel NX2 400 from the Phytoled house provides an effective and economical way to light your growing space…
Technical Data Phytoled NX2 400 Full Cycle:
– Power: 265w.
– Amount of LED: 128 x 2W
– Epileds at 90º.
– Dimension: 680x140x 390mm.
– Supported temperature range: -20°C/+40°C.
– Voltage: 220 V
– Useful life: 50,000 hours.
– 2 years warranty.
– Made in Europe
Specifically with this equipment I had more than enough to obtain a good yield (around 450 grams of dry buds) in a growing cabinet of 1.20 x 1.20 meters, since its power of 265W is equivalent to a 600W HPS. All this stuff starting from a fast flowering marijuana strain such as Northern Light Autoflowering genetic by PEV Bank Seeds.
Another less sophisticated form of LED lighting equipment is found in the COB LED panels, which are ideal for single crops, in very small spaces, with not requirements in climate control equipment, irrigation or anti-odour systems.
Obviously the yield of gr of dry bud per m2 which can be obtained is not the same as you can achieve with the Phytoled systems, but we can advance you that the yield you may reach with the COB LED panels will be more than satisfactory.
Each panel enlights a plant, in this way, you may have absolute control of its lighting, which you can vary, modifying the position of the panel or even the plant. Don’t be afraid to bring the LED closer to the plant, the closer the better, but make sure that the light covers all the plant mass.

Agrolite COB LED panels
This 72 W panels are made for crops in growing cabinets 60 x 60 cm: Although we maximize the yield by placing a plant for each grid of LED lights per panel, and with only about 72 w per plant, you will get precious buds full of trichomes. You may increase the number of plants under this 72W panel grid, but you’ll be diluting the lumens as the plants grow in height and plant mass.
Experience makes you reach a higher background, and I can tell you that by growing with LED lamps, I have noticed that the perfect growing pot is Texpot (made of fabric material), since LED lamps do not raise the temperature almost nothing is much better to use pots that may diffuse more easily the humidity obtained in each irrigation.
In addition, using texpot growing pots, makes the roots may be oxygenated more efficiently due to the porous tissue that this kind of growing pot provides, allowing a straight and proportionate growth of the roots, promoting also a complete, strong and vigorous plant development.
If you grow using LED lighting in winter, as these lamps don’t give off heat, maybe you should raise the temperature of your growing cabinet a bit, to do that, I used a couple of heating cables, and I solved the problema, but if you need to increase the temperature even further, you can always put a heater or an air-conditioning stuff if you prefer working in a more professional way..
What about the yield?
I’ve always used a few watts LED lighting lamps but of good quality, and many times I’ve overpassed the gram per watt yield, especially with a sativa marijuana strain like Purple Haze, which I would never have imagined it could be grown indoors, with LED lamps.
If we tell you something about fertilizer consumption..….. Many growers are afraid that because LED lamps emit little heat, watering is not required as often, so there are fewer options to feed the plants.
I believe that it should only be fertilized only when is necessary, that is, when the plant does not have enough nutrients in the substrate; if we grow our plants under LED lights do not worry about the frequency of feeding your little girls, my own experience is that you do not need to use too much fertilizer, in fact, the taste of your weed will be more delicious, even though we have not used too many nutrients.
Another issue is, how many more weeks of flowering do we need if we grow under LED lamps? The answer is 1 or 2 more weeks, but honestly it’s worth waiting. Looking at the final results (hard, heavy and compact buds full of the highest quality resin), taking into account the saving of light, fertilizers, and the low probability that a pest may destroy the crop, I don’t think it admits much discussion
You won’t have any problems with the burns on the leaves due to be too close to the LED panel – I’ve had plants with apical tips in direct contact with the COB LED panel and nothing happened – I think growing under LED is a great idea.
An example of growing under single LED light bulbs, in an homemade indoor hidden in a corner of my home:
And talking about resin, here we have a Somango (Soma Seeds) cultivated under LED lamps:
