Bunnings CFL with Clamp & On/Off Switch Cord

[gronko]

Hey all,

Just in case anyone wants CFL lights, The Ozzy Desk Lamp @ $17

and the nelson MELQ48ESNS, can't remember the exact price but it was around $25?

i would love to see a grow setup only with these!

 

[gronko]

yeah it would be nice to try and do something like DrBudGreengenes SOG using these lights only. Would be nice for a lil setup.

thanks for the heads up Gronko...

Just a quick question - how can you tell what the kelvins are for the CFL?

 

[gronko]

The box says Natural 5000K. I'm Looking at it now

[badabing1]

would that be enough for a veg light ? i was always thought you needed 6400k ?

 

[gronko]

Well its 5000 Kelvins, 5000k and above it will do pretty well for veg phase.

Ever thought of using an HID, maybe just a little one. Just have to deal with the heat.

 

[gronko]

Yeah they are good too, have you seen any @ bunnings?
I must admit that i went searching for CFLs only and seeing what was available. This was the biggest bulb i could find that could fit into this.

I'd imagine there would be floodlights or security lights you could use as well. Curious to know what other people have found... and bulbs to match.

But i thought i'd raise this subject and see what happens.

Try hydro stores or e-bay, 1000W, 600W, 400W, 250W and smaller, way more efficient. You can use HPS for the whole grow.

big watt bulbs are probably the wrong way to go in the future, with the smart metering being used by power companies cfl's are a smart way to grow for personal use

 

[gronko]

I've had HID lights in the past and now i want something thats smallish and not so hot. I like this particular light as its a flexible light and an on/off switch on the cord. It will do the job. Also i find CFLs don't "hum" like HIDs. I think thats the word to describe it.

I'm also interested in LEDs but there are really not that cost effective and easy to obtain.

Besides i feel more comfortable shopping in bunnings then in a hydro store, i feel less paranoid. Theres a million people in there.

One day a 1000W HPS equivalent globe will be the size of a cockroach. Happy times.

I missed that last paragraph. I went to the local hydro store about 5 weeks ago to get bloom nutes. It's a two hour drive.

On arrival a Victorian Police vehicle was out the front. What do I do now. Let's go to Bunnings, hope the barbie is on.

Then back to the hydro store, 2 hours later.

I was thinking about asking the operator about what happened but then thought better of it.

high man, here's a link to a better alternative than the
one you mention, still CFL's, but remote ballasted so
much cooler...they're straight too so more efficient
light distribution.

PLL Club. (if you don't know, now you know)

here's a couple pics of my clone op where you can see
1x 55watt, 23 inch bulb up top for the cloners and 3x down
below for short-term vegging of rooted clones.



for info on some lower wattage HID's you can look below.

150w HPS Club and Resource Guide......

you'll find many links in both of these threads to suppliers
who will deliver to your door and it's all legal, just lights,
so no need to worry.

hope this helps, SOG

anything between 2700k and 6400k is good i believe. warm white cfls and cool white cfls are good and replicate the sunlight best. warm white will heat up your grown box good, if it gets too hot, switch it with some cool white etc.

don't take this the wrong way man 'cause i like your work,
but the 'warm' and 'cool' designations refer to the Kelvin
temperature and not the room temperature.

the 'warms' are more red, usually 2700Kelvin which are
good for flowering, the 'cool's' are more blue, usually
6500Kelvin and they are best for vegging.

keep in mind that the plants need both red and blue
light throughout it's life cycle, just in different ratios
at different times, more blue in veg and more red in
flower.

thing is, in the spring the sun delivers more blue light
and it delivers more red in the fall, all due to the angle
of the sun as it hits the planet.

anyway, i'm no expert, just another grower who's read
so much my freeken eyes are bleedin', lol.

peace, SOG

s'all good mate i know, but the warm ones are actually physically hotter than the cool white, this is because they emit light lower in the spectrum like reds as you say. reds are right next to the infrared spectrum which is heat, cool white is further from it on the opposite side of visible spectrum closer to ultraviolet light. i use a mix the whole time so i don't bother changing for flowering in my micro box. we've tested using diff combinations playing with temp and using 4 warm white compared with 4 cool white = a huge diff. try it yourself. lol or stupidly like i have, touch either bulb and you'll see the difference haha white ones aren't bad, warm ones will burn like a bitch.

yeah man, i knew about the co-relation and i knew
you knew too, lol.

i just wanted to make sure the noob's would understand
that the 'warm' and 'cool' designations were in reference
to the temperature of the light and not the bulb.

btw, if you're still using CFL's you really should check
out that link i posted to the PLL club, way cooler, physically,
than a standard CFL.

if you do you'll find many using them horizontally, as i
do, and many using then vertically also, they are very
versatile.

anyway, glad you understand i wasn't refuting what
you had said, just clarifying a bit for the noobs.

peace, SOG

I am envisioning that italian chef from the early 90s... "youa pay toomuch!"

best prices I could find in a quick search:

PLL 55w - $12
Workhorse 8 (runs 3 bulbs) - $30

$80 per 3 PLL lights (165w) - 14,400 lumens
$240 per 9 PLL lights (495w) - 43,200 lumens


But, sometimes the wheel doesn't need to be reinvented..

$150-165 per 30 CFL lights (690w) - 45,000 lumens

(i gave a range because you might want to make yours prettier than mine lol)

Home depot sells 23watt CFLs in a case of 24 for $59.28. I use security light fixtures (about $6 a piece) and lamp cord to run the power.

Color plays a factor too, vegetative growth:
stretchy growth - 2700k
"normal" growth - 3500k
dense growth - 5000k+

Though I would concentrate on keeping the bulbs close to the plants rather than focus on color temp exclusively. CFLs are only effective when thought of as "basketballs of light" aka they have an effective range of 5 inches from the bulb in any direction.

In my experiecnce, CFL color temps effects in flowering:
bud mass - 2700k
bud mass / trich production - 3500k
trich production - 5000k+

this is on a factor of 5-15% tops. Don't get too hung up on color temps, brightness (75w per sqft is a great number to shoot for) is the most important element!

Couple fun pics (all CFL buds from this setup)

Go forth and build!
