Old School Marijuana Growers VS New School Growers – LED Grow Lights


heliospectra led marijuan grow lightIf there is one thing that I know about growing marijuana, it’s that there is always a better way to do it. Another thing that I can say for sure is that there is an endless supply of people who are certain that they know exactly what that better way to do it is. The truth is, I don’t claim to be the best grower on the planet. I know many, many people that can run circles around me with their knowledge of growing cannabis. I definitely recognize that, and I think that being a humble grower that is willing to set biases aside and learn about what works and what doesn’t from people is vital to maturing as a cannabis grower.

A lot of growers get tunnel vision. They have been doing it the same way for years, or they are studying under someone that has. They are not open to recommendations, and try to boo-hoo anything and everything that other people are doing in their gardens. It’s a reality that I have come to accept. Reading any grower article on any cannabis blog or forum, and you will see very quickly that there could be five growers in a room and there would be 12 different opinions being hurled around that same room.

I know people out there that grow with LED lights. More and more people I know, especially growers with big indoor gardens, are incorporating LED lights into their gardens, or are going LED altogether. They are fully aware that the yield from LED is not always the same as it is with HPS or MH lamps. But there is more to a profitable garden than just yield alone. You must also consider the inputs, in addition to the output. If you are growing with one light or two, then it may or may not be as important to you.

But when you are operating an industrial sized garden, you need to either incorporate LED grow lights into your garden, or you need to plan on paying inflated and ever growing power bills indefinitely into the future. And the only way you can expect to get your power bills to level out is when the power company eventually limits the amount of power you can consume, which believe me, is going to happen whether growers like it or not. America’s power grid is old, and the demands on that power grid continue to grow all the time and that is not sustainable. LED lights are the future, and if you are growing for profit, and you crunch the numbers, you will see the objective advantages of LED lights proven by math alone.

Below is an infographic from a company whose lights my good friend uses. The results are impressive, especially when you know the numbers behind the harvest. Not all LED grow lights are created equal. Do your homework, and make sure to start first with Heliospectra LED grow lights. Their lights are engineered specifically for growing purposes, and aren’t cheap LED lights like the ones that are flooding the market these days, and provide little benefit to your hungry garden:

  1. I dont understand why it has to be one or the other. Different light sources for different phases of growth is what I have always been taught. I have both LED AND HPS sources. the HPS is great for starting and finishing where the LED is awesome for the veg stage and in flowering for certain strains. Light immersion, Temp control and balanced feeding are the true keys to large, fast, healthy grows. They are all just as important. Also, genetics place a much larger role in today’s growing environment.

    Old school = Hey man don’t you have a affordable midsize car that is reliable?
    New school = why would we build a Mustang when we can build a Bugatti and make a much bigger profit.
    Actually I am Old and an old schooler but I also know that the price of electricity is not going to be coming down, only up and LEDs are the only way to stay ahead of the game. Why is it old is always associate with things that are bad where “NEW” is associated with good?
    Also I noticed only Heliospectras name mentioned as “the GOOD guys” Pretty sure Lumigrow, Kind, or California light works are all doing their part to be ” new school growers.”
    Me thinks me smells a few free lights coming someones way.

  3. The ESOI for batteries is still low. If you are looking for something that stores much more energy and lasts for a long time, then the logical alternative will be CAES from Lightsail.com. Of course, small growers would probably do ok with a Powerwall, but last time I looked, a single Powerwall is only good for 10kwh.

  4. Mike Freimann on

    simple solution to light sources. Grow outdoors if possible. Eliminate all cost and air circulation. Less nutrients needed and to 47me just a better flowers and taste always from the sun. Just find early flowering strains. AK-47 is a great outdoor strain. Hence the number 47. I had great results from purple kush and Humboldt strains like ATF.

  5. Edward R. Arnold on

    Batteries are not utility-scale storage and don’t last all that long. Growers need to start taking responsibility for providing their own power, which doesn’t trash the planet.

  6. “We recently tested a new, small-profile,
    600-W LED fixture from Heliospectra in Sweden (model LX601G). Our
    measurement using flat plane integration indicate that this fixture has
    an efficiency of 1.7 micromoles per joule, which is equal to the best
    LED and DE-HPS fixtures we tested. This fixture had a relatively broad
    distribution of photons compared to other LED fixtures we tested. The
    current retail price in US dollars is $1999.”

  7. @Bongstar420 – I can tell you that opne of the major flaws in your logic lies in the “materially more expensive to make” – this lamp includes an optics plate that ensures an even spread (spectrum and intensity) -that is not a cheap proposition… as well, this lamp includes a 70K hour fan that is considerably more durable than other fans you see in cheaper lamps

    Here’s another point of efficiency: you can duct this lamp….

  8. @Bongstar420 – another interesting measurement is the efficiency rating… I doubt there are any lamps pushing 1,900 mmole that have ratings anywhere near 1.7 mmole / joule – the rating on the lamp above….

  9. Numbers don’t lie!
    A smart man learns from his
    A wise man learns from others

  10. Got some from harbor freight
    Can’t even run a fan too long
    I use 12 v Fl. ,
    I’m trying to get T5 hooked up!

  11. That clone you got is second tier…highly likely to be lower yielding or lacking in potency or taste. Plus they spread disease rampantly. Finally, they make market supply highly volatile due to the large amount of intermittently successful growers that don’t know their butts from a hole in the ground. John Adam’s market was actually not very good

  12. The LED above is $2,000 for 600w at 1,100mmole.

    A high end economy rig would do maybe $500 for 1000w at 1,900mmole

    So lets look at the spread..

    $500 to start + $100 per year bulb + $960/ year electric

    $2000 to start + $576/year electric

    Yr1 Yr2 Yr3
    $1560 $2620 $3680
    $2576 $3152 $3728

    You’ve got to run that unit with the same harvest for 3 years to break even. This is only for rich people or folk willing to risk their necks in an industry which doesn’t reward skilled growers first.

    Finally, they have a 5 yr lifetime and a 2 year warranty.
    And guess what, they aren’t actually materially more expensive to make…its all about patenting and milking profits from new products.

  13. Solar is about to reach grid parity and the new battery factory Musk is building in NV will make it even cheaper by solving the storage problem.

  14. Slightly off subject but it’s still about
    change. I’ve been a rolling stone/nomad
    since 1962 until I landed on Pine Island 10 years ago. I’ve been to the City,
    seen the Elephant….bin der, dun dat. So if
    I was still in my teens or 20s I’d keep my fingers in Hydro. I’d give my left testicle to be a gardener in
    an orbital/Lunar-Martian habitat. It may
    take a while to get Cannabis off planet but you’ve gotta have fruit and

  15. And the only way you can expect to get your power bills to level out is when the power company eventually limits the amount of power you can consume, which believe me, is going to happen whether growers like it or not.

    Intermittent sources of supply like solar and wind will require it. They will also require higher prices for electricity.

  16. Nice. They claim the same results as
    K whatever.
    Saving electric ,lower heat less AC
    These units look cool, the only lEd
    I have seen was 4 ft long and they blasted the room purple!
    Got a headache !
    Old skool :
    Hey can I get a clone?
    “No man , can’t share my genetics ”
    “Can’t help you,sorry”
    New s kool:
    Can I get a clone?
    “No problem ,$10”

  17. I’ve been committed to LED(poured away my chemicals and went TLO at the same time) backed with vertical T5 and extra UV-B for a few years- in less than a square meter. Ceramic is my next step if the heat factor really is lower.
    Einstein said change is the only Universal constant. My observation is that the rate of change is accelerating.
