HPS or CFL?
    #823214 - 01/29/17 04:31 AM (7 years, 1 month ago)

What type of light is the best for low energy and high output?

HPS or CFL?

Does bud grown under CFL look any different because of the wave spectrum?

I might not be able to afford LED system I'm not sure yet as I heard they cost much more.

Cfl is  def a no, no. Hps very nice.
(Cfl equals light airy buds)(hps equals big dense buds)

Is it really that strick thou?

Couldnt a high amount of watts in CFL make dense buds? Or is it the fact CFL has a short "range"?

CFL can work, but you would have to use as much or more wattage than an equivalent HID light.

They work pretty well for vegetative growth though. :shrug:

If you search Cfl, the thread will pop up and you can read the whole debate on cfl/hps. BTW magash is the man and give him mad props for what he does here on this site. Best quote on that thread, "I've been under the lights since 1985"

Depends on the setup. Cheap generic fixtures tend to grow fluffier bud but good fixtures can grow dense bud.



HPS is cheapest to get into and shines a lot of light but takes the most electricity to counter the effects of the bulb, air conditioning, cooling fans, etc.

Fluorescent is good for veg and supplemental flower lighting. T5's are great because the 4' fixture covers a wide area.  They seem to fit best in side-lighting situations.

I second T-5s. But they do best 2-3" away from the plant. I'm actually going to upgrade my two footer to my four footer when ever my growbags come in the mail.

Look in my pics I had a 400 watt hps, janky set up but my temps stayed between 70-80 and those buds were juicy!!!

Not sure if thats too cheap.





They're getting cheaper and cheaper, but I don't know how the technology inside them has improved, if at all. 136w actual power draw. Some people can get by with a cheap generic that produces less if they have a small requirement. Or if you supplement it with T5 it might be alright. The warranty on stuff like that can be difficult.

This is more of a case-by-case situation, because it has more to do with the way the room gets rid of heat than it does the light. The light will always input heat into the room at an almost constant rate. If the room transfers heat really well (i.e. little or no insulation, surrounded by cold outside air, or has a good source of cool air to pull into the room after the fans have pumped out the hot air), the the room will accommodate a higher wattage light without overheating.

Adding active cooling (HVAC) will artificially increase the wattage capacity of the room, but may lead to worries over the safety of the plants in the event that the AC fails.

For small amateur grows, it appears that in order achieve similar bud quality, there actually isn't a drastic difference in heat output between equivalent lighting systems (except for higher quality LEDS, but a good one is typically too expensive for the hobby grower). The slight differences between the other lighting systems only becomes significant on a larger scale, but then initial/operating cost differences between lighting systems also becomes more significant, hence the use of HIDS in most large grow operations.

Having said all of this, I've always used  high flow inline fans and a smaller growspace  (typically 4x4 or less) for my amateur grows, properly isolated the growspace's air intake and exhaust to prevent immediate recirculation of hot air into the grow space, and relied on good air exchange and my house/apartments HVAC system to keep the air around the grow space cool. This has worked well for me, and I've managed to support a single 1000W HPS in a 4x4 space without a supplemental AC, and maintained the grow space within comfortable temperature ranges.

For contrast, my first grow was a stealthy grow that couldn't make much noise, so I shoved it in a small closet, with an LED light and very little ventilation, and that closet and the surrounding room shot up to 85 degrees during the day :shrug:

It's all about the complementary design of the room and the light. Hope this helps.

Yah that makes a lot of sense. Proper room venting can make avoiding using an A/C possible.

And about the LED. Those bastards put the "equilivent watts". Hate when they do that. Real watts under 150 :nonono:

That was the temp inside the closet, And it was in the summer time. That was my first grow, got almost three ounces dried which I was impressed with.

The reason you need more cooling in an HPS garden vs LED is that it shines/radiates all its useless energy(infra-red) on everything--the walls, equipment, the plants. Heat then needs to be transferred from that surface to the air, then out the garden from there.  In order to drive this reaction and keep your plant leaf in the optimal range (low-mid 80's) you need to cool the air to less than that (low-mid 70's).

With LED you shine less wasted light on everything, including the plants, and none off to the sides and top. The excess heat it generates is trapped in a heat sink and and exhausted directly to the air. You eliminate the need to cool the plant to counter the effects of the bulb.

Some people will tell you a watt is a watt, but its not true. It depends on how you spread those watts out that determines how much work(watts) you need to do to round them back up.

This illustration shows what I'm talking about.

True. There are a lot of factors that play into how well you can cool one of those things. Vaulted ceilings do wonders for example. If your in a tent, the room that your tent is in will factor into it.
