I run both 600 watt HPS and a 240 watt LED in my 5x5 Flower tent simultaneously. I barley can get any more then 4 plants in it at a time because of the explosive growth under DWC and the benefits of running both types of lights. Thank you for sharing this informative information. Stay Frosted!

For me the choice was made by the money I saved going form HPS to LED. and not even talking about the heat dispersion . The ambient temperature in my area is on a cool day 27 C , so with LED helps a lot .Being on a prePaid electricity grid, you can see the difference almost immediately. Great information as usual!

Reconciling all my gut feelings and knowledge from my limited experience like "wow my plants grew 2 inches over night" after I watered & fed them. To the "strength" of my shop lights vs my Fiet grow lights. To having a basic fan on with the lights to increase transpiration. Plenty of ah-ha moments like the "coulda had a V-8" commercial from several years ago lol. A light slap to the cerebral cortex. My intuition meets science 🙂.

Definitely not. Undeniably LED grows better plants people just don't run hot enough rooms when they do LED..... And that environment is easier to control with LED. Not to mention you don't need to replace bulbs, worry about ballasts, worry about popping bulbs while doing foliar sprays, etc.

This video is funny/well timed for me because I’ve been thinking of flipping the switch the other way to cover more area for less cost upfront. Lol

@freedom_born

Жыл бұрын

That less upfront cost will add up at the end of year. On avg you’re saving about $200 per year using LEDs. And that’s just the power consumption… then you have to buy new bulbs every year - then you have to buy different bulbs for flowering. While yea, HID still perform extremely well, they’re just power drains

@@freedom_born that is true but not if I can crop out enough for a year in one run with the additional power and space. But I don’t disagree, in the long run it will always be cheaper to go with LEDs. It would probably take 2-3 years of use for the light to pay for itself.

@Veni Vidi Vici I replied before i even got to the end of the video. Matt made some really good points about keeping HID/HPS (if you have them). Also said 6 hps bulbs/fixtures will cost the same as LED upfront. I guess those bulbs will prob last about a year each. So that’s almost 6yrs worth. Which should pay for itself in about a year (depending how much you would’ve spent buying the amount you yield - within that year). That would theoretically be the same for LED - it’ll pay for itself when you’ve grown enough to compare the money you would’ve spent just buying the weed instead.

@@freedom_born I spent about $120 to build my own LED system with emitters, transformers, steel tubing and extruded aluminum to illuminate 1/2 square meter. I got more than 150g trimmed bud (+popcorn and trim) 5 times in a year using less than $150 worth of energy. After more than ten years, I've replaced a handful of emitter chips and a couple drivers, but most of the lights still look bright, despite that they were rated for 75% of light after 50,000 hours. Using cheap COB horticultural lights, I could do the same, except brighter, better, and cheaper. Because I grow autos, and don't need deep canopy penetration -70 cm tall plants - LEDs are the ONLY way for me. Buy a soldering iron, 3 Watt emitters or 20 Watt COBs, and thank me later.

I appreciate the information! However this is one of the most expensive leds out there there’s a lot better options than gavita for 1/4 the cost, besides that though I see how the led gavita spectrum is actually very lackluster I think the only fair comparison would be uv/ir led just a thought though!

Comparing across the same manufacturer.

I like to put a fan facing the led driver or back of the light. It really helps cool it off, as well as circulate the warmth. Mars hydro has a 780w led for $630. The fc-e8000 covers up to 5x5 ft for veg, 4x4 for flower.

This can be beneficial, but fans fail at a higher rate than most LED's so it is a good addition, but should not be a requirement of the fixture.

iPhone sensors are about 7-10% better than android, so the accuracy is better with Apple. Photone won’t go over 2000 ppfd and 300,000 illuminence, the DLI has hours so you can check what’s needed for your cycle.

What I’d tell as owner of that very expensive par meter and owner of the several other meters including the app meters is the measurement of far red isn’t calculated with the App meters. When I measured there was a significant difference between how much additional light was measured with apogee as compared with the others. ie apogee 350 vs 300 on the others and it widened with more intensity

I found that the biggest difference between LED and HID lighting was the ability to choose light wavelength, and MINIMIZE the part of the spectrum that isn't needed (as much). By using ONLY red and blue LEDs, you will have all the light your plants need. Sure, the purple isn't the best in terms of rendering, so adding a few diodes of "white" will give the plants ALL the wavelengths they need from cyan to orange-red light, providing for the accessory pigments, as well as giving more light for the eyes to see the plants better. When you start using those royal blue emitters, you are going to get DENSE bud, like little broccolis on the stem - which can be awesome, until humid air turns to dew, and allows bud rot to hit It's easy enough to build, r have built, a rail-type LED system using readily available 3 Watt diode chips, or even those more of less purple and pink COB lights you might see for $5 per chip for a 20 or 30 watt light - the proper heat sink for these lights might cost $10, though. For less than $200, you could easily have a system able to light up a square meter beyond adequately, and using far less than 300 Watts.

Strange but I can tell you for whatever reason I grew danker buds under those old blurples and I’m not sure why? And true if it weren’t for certain factors I’d still be growing under hps

3:00 I don’t think that consumption comparison is accurate, according to my experience, HPS use 100% of the power rating but LED use 1/10th of their power rating. I’m confused on how 1000w and 78w can be so close in consumption? It’s only saving roughly a quarter of the consumption of HPS compared to using 1/10th of the power? It doesn’t seem right

The single largest issue most people face when switching from hps to led is a colder canopy temperature and this will quickly causes nutrient imbalances, specifcally phosphorus. You must always run LED rooms ten degrees hotter, this is doubly true when you supplement co2 If you know the science as to why I'm all ears. If i were to consult a company making the switch, what i mentioned above is the largest obstacle and first thing that should be mentioned.

In short it has to do with the rate of the photosynthetic reaction. Leaf temperature is important because if the leaf is "cold" the plant processing speed will be "slow", so be increasing the heat this speeds up the reaction rate.

@@DeBaccoUniversity Thanks for the heads up - so basically vpd gets thrown off. What I brought up is a huge issue on cannabis forums for people switching to LED - the problem almost always appearing in early do flower as phosphorus deficiency. The heat required for a healthy vpd seems to be in a ratio with the par value of a light also, so that the fuller spectrum of LEDs requires more total photosynthesis (or whatever scientific term is relevant) given all other variables being the same. So with LEDs you get the lower temps, while simultaneously requiring more photosynthesis, leading to very quick nutrient imbalances the moment your plants finish stretching and start budding. I've seen several operations lose out on revenue for months making the switch. LEDs are a different beast for sure.

If the Nameplate of an LED lamp says 1800 watts, are the LEDs actually using 1800 Watts? Or a lower %age…like 1800watts = 300 watt LED. On a 20 amp 120v circuit I should be able to use 5 lamps?.? If I buy a 60 watt LED light, it's actually only 9 watts, less than 1 amp. It’s based on the lumens of an incandescent bulb.
