This is why we can say that there is no “ultimate” setup, but only appropriate lighting.

Grow Room Temperature

Fall is associated with a lower sun on the horizon due to shorter days, and cannabis naturally flowers at this point to make sure it becomes pollinated.

Flowering Stage: HPS vs LED

It’s essential for us to note that each and every grow room will be different.

Powerful LED grow lights need to be kept relatively far away from your plants to avoid light burn

I really want the benefits of LEDs, but for for me personally, it’s point #1 and #5 that prevent me from switching over from HPS. If LED grow lights needed the same distance from the plants as HPS grow lights, and performed just as well with less electricity I would get one immediately!

Unfortunately, in order to fix the problem I would have needed to get a completely brand new LED panel. And although a lot of reputable LED grow light manufacturers will fix or replace broken lights if they’re still under warranty, the pain of having to send your grow light away for several weeks can have severe ramifications for your plants if it happens in the middle of a grow. At the time I ended up throwing the LED panel away and switching back to CFLs, which let me successfully finish my grow.

Efficiency – LED diodes are very electrically efficient, which could save you money over time (though the jury is still out when it comes to whether LEDs get better yields than HPS watt-for-watt). Additionally, where an HPS bulb needs to be replaced every few grows to maintain its brightness, individual LED diodes keep their brightness practically forever. With an LED grow light, it’s almost certain something else will break on the lamp before any diodes start losing their brightness.

………………..In fact, it’s clear that within the last few years LED grow technology’s immense upfront cost has decreased as competition increased, engineering furthered, and users have become more familiar with the change. Although this cost has certainly decreased, it’s clear that LED start up cost is significantly higher than HPS.

……….Here is the only category where LED could be considered the “loser”.

Cost Confusion: Although you may be paying more for an LED fixture or setup, you’ll see the return of investment within the first two years. Many growers idolize the ‘low cost’ of an HPS fixture and lamp but they disregard so many other costly factors.

……….Another key aspect for many LED fixtures is that they use the metal frame as a heat-sink, further decreasing and dissipating any heat output.

……….The reason HPS lamps generate so much heat is because the light is created by the ignition of gas within the lamp. LED fixtures utilize very thin layers of semiconductor material. These materials either have an excess or a deficient amount. This disparity between layers causes electrons to move therein generating light. The heat per watt is far greater with an HPS fixture compared to LED. This technology is far more efficient in transferring energy in to light, as it produces less heat and has a higher wattage equivalency to HPS (600w vs 1000w).

Compare for example a 10-plant grow operation for HPS; you would need at least 3 fixtures (3,000 watts), an exhaust system for each, an AC unit of at least 10,000BTU, and temperature, humidity, and Co2 controls. This could rack up to upwards of 7,000 watts!

In this post, we will conclusively compare the specific benefits and detriments to each grow light technology.*

Trial and Error: Many growers are willing to make the change, increasingly so as technology advances and fellow industry peers change their styles and systems.
