correct spectrum combination,help needed

hi guys.,growing noob is here

i am making a growing box.its size is 1 metre x 1 metre x 1 metre
(nearly 10 sqft. )

i know 6500 k for vegation and 2700k for flower.
but i want to use same lambs from beginning to harvest.

i will use 10 x 55 WATT CFL lambs. (3300Lm is each one )
how can i set up correct spectrum combination?
5 lambs that are 2700k and other 5 lambs that are 6500 k is correct combination ?

I mean you said it your self that 6500k is best for vegging. I think if your putting 2700k's in your veg box its just a waste of light/power. If i was you i would use 5500k and 6500k bulbs together for veg. And then for flower just use the 2700k bulbs. Um how many plants to you plan on growing? Thats a lot of cfl's your talking about using, very interested in seing this one all the way through. Good Luck

1)
do i have to use absolutely different spectrum lambs for vegging and flowering ?it means that i would have to buy same lambs at twice for diffrerent spektrum.
10 x 50w @ 2700k for flowerng and 10 x 50w @6500k for vegging.
it will be too expensive

therefore, i want to use same lambs from beginning to harvest.is it not possibe ?

2)
i will grow 5 plant for first time.
i read that ''minumum 50 watt (2000 or 3000Lm ) needed for 1 sq ft.'' i have 10sqft so i should use 500 watt lamb,shouldnt i ?


3)
and last thing
i think,the best way for 500 watt is 10 x 50 watt.i wonder it is true or i should use other combinations like 5 x 100 watt or 12 x 42 watt ... etc ?

you need to use different spectrums for veg and flower. you can get away with using less light during vegging, and as much as possible for flowering. the more light you have the better, so spend as much as you can on flowering.

Plants "veg" better under 5500-6500k light. It's a much whiter light which contains the right spectrum the plants need during the vegatative growth stage. When you start to flower, a more orange light is needed (2700k) to kind of trick the plants into thinking it's becoming autumn and the season is up so they flower. The 2700k would be wasted electricity (well not completely) during veg, and the 6500k bulbs would not be ideal for flowering.

Why not consider gettin a hps? Surely you could get a 400w hps lamp for a similar price which would work from start to finish and depending on who you listen to, could give you better results than cfl's.

It's also not all about how many watts u got per sq. foot. It's about how much 'lumens' they put out. I'm no expert but lumens are basically the usuable light. a good 400w will put out prob 50,000+ lumens. 12 of your 3000lumen cfl's will only hit 36,000.

Do some reading in the other forum sections about lighting. you'll learn alot.

thanks guys ,i am scanning forums for weeks .my englihs is suck so i cant understand properly all things.

So;

1)

i want to prefer CFL because if i use cfl,i wont need complex ventilation systems and therefore the system would work more quietly .
i have read a lot of topic and i learned that ''for more quiet growbox,i should use CFL '' .
i will put the growbox on my bedroom and i want some peace and i dont want to hear noise of big fans while i am sleeping.

of course,all of them is opinions of a newbie .
now please tell me,my opinions are true ?

2)
if i am right;please tell me how should i make totally 500 watt cfl lambs ?

i think,the best way for 500 watt is 10 x 50 watt.i wonder it is true or i should use other combinations like 5 x 100 watt or 12 x 42 watt ... etc ?

3)

i read that '' cfl must be close to plants as well as possible (nearly min 5cm and max 10 cm )
i wonder there is the same rule for hps ?

example 1 '' the distance between my plants and cfl lambs is 50 cm'' . Well, this exapmle is wrong beacuse max distance should be 10 cm while using cfl

example 2 ,'' the distance between my plants and hps is 50 cm''.this example is true ?


thanks

Don't listen to the bullshit. If you are on a budget, I'd suggest 2700k bulbs only. I have been using them for vegging and my plants look much bigger than 90% of the other CFL posts I see for the same time(not to mention I've cut them twice and have been LSTing).

2700k work just fine for vegging. It's all about how close they are to the plants. I use 2 68w 2700k CFLs, and 4 26w 2700k CFLs.

They are setup like this, where [] are the big 68w CFLs, and X is the (4) 26w CFLs mounted on 3 V-splitters.

exactly dont listen to the bullshit (above) vegging with 2700k is not a good suggestion when he already have 6500k lights. If you dont cut corners with lighting its a good investment.

If he already has 6500k then sure, use those for vegging. I'm saying that 2700k work fine for vegging, and if you say otherwise you clearly don't know what you're talking about.

If you have no lights yet, get 2700k if you can only afford one type.

cfls are not expensive so just get the money and find a good price

If you have a 12+ light setup, buying the bulbs in both 6500k and 2700k, you might as well get an HPS if you are going for budget buy.

yea cfls are great in small spaces but if you have room for an hps go for that if you have ac in your grow room or room for some 12 in fans do that you wont need noisy ass fans for a 400 watt hps

i'd use 3 lambs, 2 goats and a chicken...
