To CFL or not to CFL

[TD.]

Was just wondering if it's worth buying 2 more CFL's with the 2700K for flowering? Does it really give a significant yield increase?

buy as many as u can fit in there, the more light there is for the plants the more of there potential u will be tapping into, less lights is simulating a plant struggling to get natural sunlight.

 

my mate built the box and put like a vent thing on top and the desk fan seems to cool it fine it's not really hot in there at all i leave it on 24/7.

 

if u buy and install more lights ( im going to assume u arnt doing your own wiring, which sucks IMO ) then the heat will increase, u can kill 2 birds with one stone by putting an intake fan in a place that allows the air its thrusting to blow on the spot u will have your buds at. thus eliminating the need for an internal desk fan, making more free room for more bulbs and more bulbs is always better growth....... but what do i know, im not an electrician

I'm not really very serious about this grow it's just a bit of fun. My main grow is outdoors. What i meant to ask was that given i only have 2 light fixtures to put bulbs in, would it be better if i use the 5000K bulbs in them for vegging, then when i want to flower, swap in 2 2700K bulbs?

truth be told i have both in my current grow and i have noticed sweet fuck all in difference between a 2700*K bulb and a 4000*K bulb. u would think there is a difference.....but the plant dosnt seem to notice. also y dont u buy more lighting fixtures and just wire it up ?? CFL's use only active and neutral (well anything under 40watts im sure of). u can tell the difference between + and - cant u ? Edited August 3, 2008 by TD.

Haha thats not the problem. Just lack of funds and too busy with uni and other stuff to really go out of my way that much for it. So you think it's not worth swapping the bulbs out come flowering time? Anyone else have an opinion on using different CFL bulbs for flowering than vegging?

I am looking at CFL's for my vege chamber but I am not sure which one to go for? From what I've read so far I should be looking for as high wattage as possible and 6400K color temp...

 

There is a 130W no name bulb on ebay that fits the bill..?! $60 incl delivery

Or alternatively a "Spectrum 135W" bulb from the grow shop for ~$80

Or go cheap with a Bunnings/Supermarket household CFL??

 

This is purely for vege growth and clones. I don't even need plants to grow fast as space is limited. I got HPS in the flower chamber.

This is still theory for me but what I can tell MH hid used for veg is + 10 000 Kelvin. HPS hid is around 3000 Kelvin mainly used for flowering.

 

Using this info and when thedarkstone (post13) dropped that there is a 14 000 Kelvin 120w CFL it sounded a good choice.

with only $20 difference between the no name bulb and the spectrum bulb u should already know which one to pick, as for the cheap'o bunnings CFL's there your pick if your on an uber tight budget and just want lots of bulbs.

 

just because the bulb is cheap as chips dosnt mean it wont work, the plant wont refuse to grow because u shopped at bunnings and not a hydro shop

ok so it looks like i'm way off track already on my first grow. i had 2 x 23w cfl's (2700k) lying around so i thought i'd use them for the veg. is this just a complete waste of time? i'm waiting on my 400w hps kit to arrive so is it even worth starting the grow with these bulbs?

 

sorry for the thread hijack

[ianTE]

Not a total waste of time, you dont say how many plants you have how big they are. The HPS will give basically the same color temp.

Bunnings has 5 pack of nelson 4000k for just under $12

 

I went with darkstones recommendation and bought a spectrum 130w 14000k CFL its very blue

i haven't even germinated my seeds yet. i was going to wait til i have everything spot on for my first grow. i plan on growing 2 or 3.
