Cannabis Cultivation Tips: How To Set Up Indoor Grow Lights
Cannabis is useful even for aspiring gardeners looking for a single plant to raise. The species is versatile, resilient, and relatively resistant to damage and infestation. For the aspiring marijuana user, growing weed at home can potentially save you a fortune. You can cut out the middleman and cultivate the herb from seed to flower, and ultimately to joint.
But It's difficult to provide correct light intensity for your cannabis growth.
Excess light can damage your cannabis plants as much as too little light. Learn all you need to know about light as it relates to cannabis, and how to properly set up your grow lights for massive indoor harvests.
LED systems produce higher PAR than MH, HPS, and other kinds of lamps. Despite that, your plants will need about the same amount of watts per square metre to achieve a harvest similar to that of traditional HID bulbs. Also consider that LED light systems are often advertised as being more powerful than their actual electrical power draw, but this doesn’t mean that a 400W LED can cover the same square footage as a 1,000W HPS bulb. Here are some general charts of the power needed to grow vigorous cannabis plants using different lighting systems. During the early vegetative stage, they will need around half the power.
As a reference, HPS lights can approximately cover the following canopy areas:
250W ≈ 0.5–1m² ≈ 2 plants
400W ≈ 1–1.5m² ≈ 4 plants
600W ≈ 1.3–2m² ≈ 8 plants
1000W ≈ 1.8–3m² ≈ 10 plants
LED lights can approximately cover the following canopy areas:
120W ≈ 0.5m² ≈ 1 plant
200W ≈ 0.8m² ≈ 2 plants
280W ≈ 1m² ≈ 4 plants
350W ≈ 1.5m² ≈ 6–8 plants
To get an idea of how much light intensity you are providing to your plants, you can buy a lux meter and measure the light intensity over different points of the canopy. Alternatively, you can do a theoretical calculation that considers the lumens emitted by the lamp in relation to the grow surface. In order to calculate the lux pressure on the canopy, just divide the lumens of your lamp by the square metres of the illuminated surface. If you position a lamp that produces 100,000lm at a distance of 1m from the plant’s top, it will illuminate an area of 1m² with an intensity of 100,000lx (100,000lm ÷ 1m = 100,000lx). If the lamp is only 0.5m away, it will receive 100,000lm ÷ 0.5m = 200,000lx.
Unfortunately, the luminous intensity decreases by a factor equal to the square of the source distance from the illuminated object, therefore your same lamp placed at two metres will increase its beam width, covering 4m², but with only 25,000lx. Consequently, you would need four lamps to reach your hypothetical 100,000lx target on your whole grow area.
According to above we know that the right number of lights and suitable distance are both important, all of growers should learn more about that, also, get a best grow light will help you more, make your growth more smooth.
The 1800+ covers a 5 ft x 5 ft flower footprint and a 7 ft x 7 ft veg footprint. This unit is backed by Lex Commercials industry leading 7 year warranty. This distinction means each unit is covered by a 7 year full manufacturer’s warranty, has a 100,000 hour life rating, is ETL listed and you will never have to change a bulb again.
The Lex Grow 1800+ is designed to meet the needs of commercial and home growers alike. We understand excessive power consumption, bulb replacements and heat are the biggest problems indoor growers face. The Lex Grow line alleviates all of those issues. Coming in at over 2.8 PPF/Watt, the Lex Grow is the most efficient full spectrum LED, period.
Lex Grow 1800+ Full Spectrum provides the same sun-like qualities plants love without the negatives of high energy requirements and high heat. Using Lex Grow’s Full Spectrum you will see faster growth and most importantly increased production overall.
