6400k CFL bulb with hood for growing an autoflower
    #816126 - 06/30/16 01:09 PM (5 months, 2 days ago)

hi,

I am strongly considering getting a 6400k CFL bulb with reflective hood for growing one autoflowering plant. I read that this type of bulb is great for an autoflower and will also work perfectly for flowering. I wanted to know what people's thoughts were on this. I would be keeping the light on a 24 hour light cycle. I actually read that this type of bulb would produce excellent dense buds even though it is sold as a "vegetative growth" bulb.
Any advice from experienced growers would be very much appreciated,
thanks

What wattage?
Most autos prefer 20/4 light cycle, tends to be less stressful on the plant, and auto's hate stress.
At 6400k it's a better veg bulb than flower, but would work.
2100 to 2700k tend to produce the best flowers.

it's a 400 watt CFL and emits 10,000 lumens, plus I would be fixing it into a reflective aluminum hood. It seems like it would be sufficient for at least one autoflowering plant, maybe two.

I read elsewhere that the 6400 produces more dense and potent buds than the 2700, with pictures to back it up :smile:

thanks for the advice

A four hundred watt cfl?  Are you sure it isn't an hps?

I highly recommend a 400 digital system over a cfl system.
With the digital you can run either MH or HPS bulbs.
Produces less heat than that cfl as well.
Plus about 35000+ lums more than that cfl.
It's 400 watt either way, may as well get the best bang for your buck.

Also pics don't prove potency.
The 6000k lights produces tighter buds, with a bit more resin at a lower yield that is fact.
But the 2000k lights produces higher yields.
Potency comes from genetics and proper care in my experience.

ah, sorry, my mistake. It's a 200 watt CFL, but it's output is that of a 400w metal halide (or so it says on the website). And its 10,000 lumens. Add to that the fact that it will be screwed into a light-reflecting aluminum hood and it definitely seems like it would be more than enough for two small plants (autoflowers).

If I'm understanding correctly, 400W MH or HPS put out a lot more than 10,000 lumens... Maybe it would be better to run a 250W HPS for 2 plants?

yes its true the HID lights (hps & mh) put out much more lumens. But the CFL is just so much more convenient and easy and energy saving and cheaper. Also its not a fire hazard. And HID lights require ballasts and also vents to keep it from overheating. The CFL is totally self-ballasted, so all one has to do is screw it into a fixture.

I wanted to get a 150w hps but even that small of a light requires a whole ballast system which takes up so much space that I don't have. CFL just seems like the best all-around choice to grow one or two small plants (for me anyway).

Don't underestimate the heat of that cfl, and don't forget you will still need ventilation.
Air exchange is very important, plants must breath to live.
CFL bulbs have the ballast built in so it's in the tent with the plants making heat.
HID lights in most cases the ballast is remote, so it can be kept outside the tent, which of course means less heat inside the tent.

energy saving



Says who?
It is going to pull 200 watts, and to be completely honest a 150 watt HPS would produce a much better crop, with less heat, and a higher yield at 50 watt less energy.

I understand if money is the issue, I just want you to have the best facts for your choice.
I'm not a salesman so I'm not going to lie to you and tell ya that a 200watt cfl producing 10000 lums is equal to a 400 watt HID producing 40000+ lums.
Because in no way do they compare.

Watts are the rate of electricity being consumed by the unit, directly related to KWH.

A 200W CFL uses .2 kilowatt hours when it's in use. Produces 10,000 lumens as per that manufacturers advert. 150W HID uses .15KWH, produces 15,000 lumens. For example, if you are running a 12/12 cycle for a 30 day month:

360 hours per light @ 18 cents per KWH from your electric provider

CFL: 360 hours x .2 KWH x $.18 = $12.96 @ 10,000 lumens

HID: 360 hours x .15 KWH x $.18 = $9.72 @ 15,000 lumens

So the HID produces 50% more lumens, while being 75% of the cost of the CFL in terms of energy. Plus the point that was just made about it creating extra heat with the internal ballast, etc.

yes i realize that hps lights are better for indoor gardening than CFL lights. But It's too complicated for me set up an hps grow room; I really can't do that where I live. It's much easier for me to buy a simple bulb that I just screw in and turn on. Also from what i've read elsewhere, 10,000 lumens and 400w output is sufficient to grow one plant. I am not trying to start a farm.

OK gotcha so enough about your light options seems your mind is made up.

Thanks you Sloppy for spelling it out as far as energy savings go.:thumbup:

CFL's are still more environmentally friendly than HPS lights, this is a simple fact.

How so???
They contain mercury, so breaking one isn't so friendly to the environment imo.

But enough about the light, your mind is made up.

I am truly interested in your ventilation plans.
Do you have one?

TBH I don't know how I am going to create a grow space once I get an apartment. I really just want to grow 1-3 plants, that's all.

I live in the northeast (united states). If I get my seeds in 2 weeks would I still have enough time to grow a few plants outdoors? I would basically have from mid-July to the first week of October. They would be regular seeds not autoflowering.

thanks for your replies i appreciate it

You live in the northeast and want to grow plants in an apartment? I'm moving away from the northeast to grow plants in an apartment.

Stoneth is right, you need a SERIOUS ventilation plan, now especially. IMO it's just flat out not worth it, but do you man.

yes but i'm medical marijuana patient so I can legally grow up to 6 plants in the state that I live in. This is also why I'm considering growing outdoors under the sun so that I don't need to worry about grow rooms, lights, ventilation, etc. I just hope that 11-12 weeks would be enough time, otherwise I would have to either wait until next summer or just grow indoors once I get an apartment.

You will not have time to grow outdoors this year. I stayed in May, and still feel like I'm behind the curve.

Set your sights on next year, and have a well thought out plan on hotter you want your grow to go.  Half assing this will only result in fake at worst, and a really shitty crop at best.
