What Ed Rosenthal Said

From Ed Rosenthal: (I spun his message to avoid plagiarism banishment) 
 In the new Skunk Magazine there was a question in the "Ask Ed" section That I thought was worth posting here for people thinking about using CFL's or HID's for a stealth grow room. . . .

The Asked Question Was: I intend to grow a single cannabis plant in a space
1' x 2'. What light would you recommend? I was think of using four 30-watt compact fluorescent lamps. Will this be enough? Cost isn't an issue but I am deterred from getting a high pressure sodium light because of the amount of heat the bulb produces.

 The Answer Is: As you mentioned, you have several lighting systems to choose from, including compact fluorescent s and high pressure sodium (HPS) lamps. Among HPS lamps you have a choice between a single 100-watt lamp which uses a total of about 120-watts and emits about 8,800 lumen (73 lumen  per watt) or a 150-watt lamp, which uses about 180 watts and emits almost double that-15,800 lumen (87 lumen per watt).
 A 42-watt compact fluorescent (CFL) emits about 2700 lumen (64 lumen per watt). Four 42 watt CFLs use 168 watts and emit 10,800 lumen. Other size CFLs have a similar efficiency, however, that is only part of the story.
SuperMax CFL Grow Lights Marijuana plants use mostly all red and blue light. Green and yellow light is of little to no use to them, so light or lumen that is put out in these color spectrum’s is totally wasted energy. Pretty much all of the light emitted by HPS growing lamps is in the yellow color spectrum or kelvin. Only a small amount of the light put out by them is in the red or orange color spectrum’s, that plants use efficiently and thrive on. Meanwhile, warm white CFL's bulbs (2700 Kelvin) emit a greater portion of their lumen in the red and orange kelvin sectors.
 Although CFL bulbs produce only about 75% of the light per watt that the HPS does, the amount of light usable by the plant is at least equal or higher with the fluorescents or CFL grow lights. You might want to experiment your self to see if adding just one cool white (6500k) CFL to replace one warm white results in shorter, stouter stems and more vigorous bud growth in bloom. The reason this is that warm whites (2,100 – 2,700k) don't emit hardly any blue light, which the plants need to regulate their growth and for photosynthesis. Having just one cool white bulb supplies the blue light needed in bloom.
  My advice for your grow space would be to use several (three to five) CFL's bulbs with a combined input of around 120-160 watts. Even though the 150 watt HPS grow light is slightly more efficient that the CFLs grow light in total lumen output, watt for wattage the compact fluorescents provide as much useful light as the HPS grow lamp.
  Heat is also another factor to consider. Consider that a HPS grow unit will run much hotter and emit more heat than the flourescents ever will. Make sure your using good reflective material around & in the garden so that any excess light trying to escape the garden will be reflected back to your plants. Any light that doesn't get to your plants leaves is completely wasted.

Can you really grow killer weed using cfl grow lights?

Can you really grow killer weed using cfl grow lights?

   OK lets face it, by now we all know you can grow weed with CFL grow lights, but can you grow good weed? To answer bluntly, yes you can. Not only can you grow killer weed using powerful CFL systems, but you can rival traditional more expensive grow lights in yield and quality!

  The key to using CFL's as grow lighting is in just how they are applied. First, use plenty of light. I mean LOTS of light. Don’t get skimpy on the CFL's, they last a long time and are still much cheaper then the alternative's. I recommend getting the 2000 watt CFL system from for flower simply because its the best and most powerful CFL flowering unit available. Not only that but they are "Plug and Play" ready while being pretty inexpensive.

  CFL's in the flower cycle should be placed as close as 2” to the plants, while never being farther than 10” from the tops. In short, keep your grow area to about 2 ½ feet to 3 ft under your grow lamps for optimum performance.
   People mistakenly use CFL's like HiD's or HPS lights and expect the same results, but that can only be achieved by using the CFL lights properly. CFL's do not penetrate as far as HiD or HPS lamps do because of the lower Lumen count, however in the first three feet of light, CFL grow lights can exceed HiD, and HPS systems in USABLE lumen. Meaning the CFL grow lights produce less overall lumen but more lumen in what the plants need. Thus more advanced growing methods such as, scrogging, pinching, sea of green, and lollipoping are highly recommended when using CFL grow lights. In fact whether your using traditional grow lights or alternative grow lights such as CFL's, those methods are still highly recommended. Even using HiD's, or HPS units, the growth under three feet tends to be wispy, popcorny and unsuitable for medical use.


   Make no mistake! CFL vegetation growlights are the most powerful inexpensive vegetation lights out there. Period.
   OK, I'll explain. Today about half of all indoor growers still use T-8 or T-5 fluorescent tube setups for their plants during the vegetation cycle with good results. Fluorescent are widely believed to be the closest artificial light to sunlight. Its no wonder tanning beds use fluorescent light. CFL's or compact fluorescent lights are the same type of light only in a compact from. CFL bulbs are easier to position, and provide more intense light in the same space over traditional fluorescent tubes do.
   While traditional 400 watt and 650 watt T-8's and T-5's have done a pretty good job, using a 1400 watt or 2000 watt CFL growlight system makes a lot more sense. With one of those units your getting 3 – 5 X's the light from a unit with roughly the same initial cost. Many people report getting 2” - 4” inches of growth a day using powerful CFL grow lights.


  Hey CFL grow lights might not be for you, but if your into saving money, electricity and headaches while still growing some good quality bud, you might wanna give em a try.

  While technology has changed the way we grow marijuana indoors dramatically over the last two decades, surprisingly most growers still use and believe in outdated lighting equipment.   
 Today’s growers have access to the best and most sophisticated growing systems of all time, but still fail to upgrade one key!
We took a look at the different new alternatives to the traditional HPS, MH and T- type set ups in favor of the newer and in some cases more energy conscience grow light setups. More specifically I'm talking about LED and CFL Grow Light units.
After testing and independent research on both types of grow lights the CFL units came out heads and shoulders above LED's, MH, and yes, even HPS grow light units!

Keep in mind not all CFL grow lights are createdequal! CFL systems need slightly more than the stated equivalent to get the same results as HPS or MH (not the same power bill tho..) CFL bulbs must also be pointed in the correct direction with a directional hood for the maximum benefit.
 We did find one company from Oregon that’s got it right:

Those guys build a 1400 watt veg unit that kicks ass! They also build a couple bigger unit’s but the 1400w unit it is like having a 1000k HPS AND a 200w MH light together all in one unit! 
 These are the best grow lights period.

Todays Stealth Marijuana Grow Lighting

  There was a time not so long ago when growing marijuana indoors was a crazy proposition fraught with the real and constant danger of going to jail. A time when stealth growing indoors meant you had to watch the power consumption closely and the heat signature from the HPS bulbs if you grew in the attic of your home. 

  Stealth or Ninja growing meant taking a huge risk since growing was illegal in all states just a few years ago. The equipment available to growers at that time just wasn't stealthy or ninja like. In fact, compared to some of today's options, the clunky HPS and MH hoods and ballast combo's seem like using the old "brick" phone vs today's iPhone and Androids.
  Today things are much different. Today's growers have tons of equipment options for any scenario imaginable since now marijuana is semi legal in 13 states and counting. Because of this increase in demand, today's growers have more grow light choices than ever. CFL's to HPS, MH, Fluorescent, with LED's, all vie for attention for today's modern indoor marijuana ninja growers and traditional pot growers. 
 While not all growers are convinced, there has been a clear winner in the battle for the best indoor grow light based on the results. CFL systems, if constructed properly outperformed other light sources. To be fair, the LED's  also perform very well, but their initial cost to purchase, small light spread and unreliability (the individual LEDs go out and can not be replaced) pretty much ex's LEDs out. However for the smaller stealth grow boxes LED's are king. 
  For everything else CFL's are by far and away the best stealth and non stealth indoor grow option. CFL units can provide more light for vegetation in the same space than any traditional fluorescent unit (T-5's & MH) and as much or more light in the flowering stage than HPS units can provide. 
  One company, has designed what looks to be the best CFL fixture yet. They sell a 1400w unit that outperforms the best 1000w HPS units at a fraction of the cost for any 1000w hps system. 

  So where do I start? There's so many benefits...Ever burned a plant before? Yea, me too and it sucks! You wont burn your plants with CFL's! And did you know a 1000W HPS unit is capable of producing over 150,000 lumen? Did you know ONLY 13% of all that lumen is actually usable to plants? Yup, that's right. So a kick ass 1000w HPS system is going to give you a cool 19,500 - 20,000 lumen for 6 months while costing you $150 - $200 bucks a month in power. Meanwhile the 1400w CFL grow light system kicks out 24,400 lumen IN THE COLOR SPECTRUM'S THE PLANTS NEED for 2+ years without any light quality degradation and a power consumption bill under $50 bucks. Oh, and with the CFL's ...I don't need a fan just to cool my lights. ☺
