When comparing both technologies, always compare light levels of the entire grow and not just fixture to fixture. That simply does not exist in the marketplace. Yes, there are LED fixtures that exist when measured directly beneath the fixture.
The output looks equal to or even greater than an HPS. Most LEDs are a very directional source of lighting. If a supplier cannot provide you with these numbers then it may not be someone you should be considering. Another area you should always do your own math on is the BTU calculation for your grow room.
As the cost to cool your grow room can be one of your highest production costs. This is simple math as 1 watt equals 3. Do this math with your LEDs as well. While that looks like a big savings it will take at least two times the amount of our LEDs to get to the same light level as a w HPS. On the other side of this argument is that the LED fixtures do not provide the radiant heat as HPS and your crop roots will perform better with warmth.
It is proven that there is a direct correlation between heat and crop production. Plants grow slower, producing less fruit the colder they are. In northern climates many growers rely on the heat from HPS to warm their crops. This is a big consideration to consider when comparing these technologies.
There is no easy math to calculate an ROI for this but when comparing light plans from one source of light to another be sure to take into consideration the distance of the light source from the canopy.
There is a big misconception in the industry stemming from the LED suppliers that the ability to have your LED lights so much closer to your crop will help increase production lower into the crop.
This could not be further from the truth! When your light source is closer to the top of the canopy than the shadows created from the top layer of leaves are much bigger than if the light was further away.
Use a flashlight and make a shadow on a wall with your hand. Once they are a foot tall, they can safely be placed under High intensity lamps. Hey Darren, for help with growing we have experts standing ready on the support forum. Any sales related questions can be asked through [email protected].
Robert, I am a new grower and I am researching and experimenting as I go. I am currently using the via par spectra which has built-in fans and lighting for all stages. It suggested in the pamphlets that I use the lights with the lights on for both growing in flowering. So I just turned all of the lights on and have them approximately 30 inches above the plant however I read another article by you that you suggested it be a lot lower. Do you know if there is a way for me to contact you or someone at your company for some assistance.
After much research I resolve that your website and your company was the company I wanted to do business with unfortunately I had problems purchasing seeds from your company because I live in America and something to do with banking I have since work is through most of those problems unfortunately I purchased some seeds from another company. Again my goal is to use your Company moving forward.
Rather than putting everything on an email I was wondering if there was a way for me to contact someone at your company. Thanks again for all you do and I will look forward to an email mail from you or someone at your company take care and God bless.
Joe — LEDs are not standardized like other lighting types and therefore vary greatly. You should always chech with the manufacturer though to see what they recommend and then adjust the height if need be. I have a box 4. You will be able to grow successfully with all thjose little lamps. You will have to temper your expectations for yield. Plants will not flourish as well under those l;amps due to lack of light penetration and intensity.
I would look into a watt Iposer system. It is a switchable digital ballast with hod and lamp bulbs included. In a closet space of 3x7x8 thinking of using watt cfl and two t5 fixure in each corner using t5 54 watt is this a bad or good idea or do I need to do something different.
I suggest an Ipower system. Ipower digital systems come complete with all you need. Available on Amazon. I have placed links to these products on Amazon, for you to choose from.
Autoflowers can be grown insife or outside. We know they produce great results — there is no question about it. They are also a very practical option. Better yet, these lights are some of the most efficient lights on the market maybe excluding some cutting edge LED lights.
I dont think you need a light schedule , it aready comes modified to flower on any light schedule,but is the ideal light schedule!!
This site is wonderful. Growing white widow autoflower. My question is this: I understand that as soon as the plant emerges it emerges in the flowering stage.
Therefore, what is the best light for an autoflower light. Just growing 2 plants in small space. Your thoughts are greatly appreciated. Thanks, Terri. Just a passing thought. Have a great day. Keep it green. This will give you a more accurate spectrum of light, which is very important for […]. Honestly, As a new grower; You probably should invest in digital switchable ballasts. Everything you need. You can but 2 or 3. Robert Have you used or do you know anyone using the new Dimlux expert series watt double ended bulb lights ,if so what is your thoughts on them and how do you set them up.
My hydro shop says you put them right at the top of your tent and let your plants grow into them, I think this will cause streching not what I want what do you think. You can also prevent bad bacteria from getting […]. This is a common method for all gardeners to use on their […].
A certain type of light is necessary. The strength and specific color of the light matters for photosynthesis to take place accurately. For instance, blue light is necessary during the growth process and once it is time to start blooming, your plant needs red and orange light.
There are unique lamps that exist just for this purpose. Read more in the article Best marijuana grow lights […]. Grow Bible. Marijuana Light Cycle One of the easiest to control and most important factors contributing to cannabis growth are the light cycles. Harvest Guide. HID — High Intensity Discharge Lights High-intensity discharge grow light were first invented for a huge scale, for use in public arenas and stadiums.
Optimal Lighting. Can I use any LED light as a grow light for my plants? What light color causes the most growth in plants? It is believed that blue color yields the most growth in plants. What types of grow lights are there? How good or bad are my Mars Hydro lights watts. Can you use both lights blossoms for your growing pot inside.
Sorry Arthur, the above post was meant for Alan. Is it harmful to use spray milk water on flowering to keep mold at bay? In contrast, HPS lighting is frequently used in the blooming phase.
We offer a rundown of the most common options below. Are you stuck for time? Check out the pros and cons of each at a glance. Short for light-emitting diode, an LED is a simple form of light with an efficient energy signature.
Due to how the light is generated within an LED, they use a meager amount of electricity for the same amount of light compared to other sources. However, LEDs have a pricing problem. The lights you need for cultivating cannabis are costly. If you want to invest in your bud correctly, prepare to spend a substantial amount of money. One great benefit of LED grow lights is that they create comparatively little heat compared to other types of light.
Marijuana plants like a warm environment. However, excessive heat damages them and may also cause a fire in your grow room. LED grow lights can also distribute a fuller light spectrum due to how the light is created through electroluminescence. This can result in a better, higher quality yield from your bud. This benefit is somewhat counteracted by the fact that the average LED light board is quite low-powered. As a result, you either require multiple boards or a huge, single one.
Also, you only get the best results with LEDs that offer a full spectrum of light. HID grow lights, short for High-Intensity Discharge, are large light bulbs that emit a tremendous amount of heat and light.
They usually require a full exhaust fan to remove the excess heat, and electricity consumption is enormous. Also, they generally need a decent amount of time and space to set up a properly working system. Metal Halide or MH grow lights are primarily used during the vegetative stage. MH lights produce a strongly blue-tinged light, which the plants prefer at this stage of growth. It might sound strange that a plant prefers a type of light.
However, different colored lights are mostly just different wavelengths and intensities. Due to this difference in wavelength, the plant prefers stronger or weaker lights at various stages of its development.
They emit a gentler, yellow light that cannabis prefers when it is in the flowering stage. Some plants, such as microgreens, may flourish under basic desk lamps, according to Zartarian. But cannabis plants need brighter and more consistent light to carry them into maturity.
At the same time, cannabis plants need a so-called "dark period" during the flowering stage, but ample light is key throughout most of the marijuana plant life cycle. So, not just any light will do the job. Bottom line: Investing in high-quality LED lights for your indoor garden may pay off in the long run. Even if you no longer use incandescent or halogen bulbs and have opted for LED lighting, it is unlikely that the lights in your home will be sufficient for your cannabis plants.
Schimelpfenig cited the simple reason that the lamps in your house are designed for human eyes, not marijuana plants. Bottom line: Choosing an LED grow light specifically designed for plants is a reliable way to ensure an abundant harvest.
The cost of operating indoor grow lights varies depending on wattage and how much light you are shining on your plant through each growth stage.
Since young plants require less light, energy costs are likely to be lower during this stage.
