yet another light bulb question!

[lvl i k e y]

my fixture holds 6 bulbs. i have 4 grow t5 6500k bulbs and 4 3000k t5 bloom bulbs. should i just use 3 of each in my fixture or should i use 4 grow and 2 bloom for veg. and 4 bloom and 2 grow for my flower? will these different setups make any difference or would anybody recommend any other way?

Start with half and half and place some plants down the middle of them. After a few days, whichever side the plants lean toward is the better bulb.

If thats all you got, then how you suggested it is the best way. Although I would switch the 4 3000k and 2 6500k for last week or 2 of veg as it helps them adjust to the change. Idk how many plants are or how big your grow is, but thats not alot of lumens there, try get more lights if you can.

I dont think wether one bulb is 6500k or 3000k will make much of a difference,but i'd go half and half. one bloom, one veg,one bloom, one veg, one bloom, one veg

Umm, I have to disagree there, blue wavelength (ie 6500k) for veg, red (ie3000k) for flowering. So a 50/50 mix will just mean wasted PAR in both phases.

 

[darkdestruction420]

no it wont, plant have 2 types of chloroplasts, one that interacts with red wavelength and one with blue, not using a mixed spectrum is what wastes it.

Man, you really haven't read up on weed much... Why you think people don't use HPS for veg growth?

 

[darkdestruction420]

sorry, but its obvious you read some little book and think you know what your talking about, people use hps to veg all the time. I think im just going to ignore you though since you keep saying i dont know what im talking about and dont actually add anything.

 

[Captain Jaz]

Here you go...

Lol, i think that everyone should ignore what your saying, because it make no sense, and is just plain ill-informed.

 

[darkdestruction420]

so you list some little chart you found, how cute......done any actual growing? do you know the sun puts out both spectrums and plants are adapted to that?

 

[Captain Jaz]

I just hope this guy and other people you advise have the sense to look at other people advice to and don't mess up their grow because of you.

Yes, mate, and I grow better stuff than you for a long time, yes, the plant uses both types of light. In summer, when the plant is vegitating the light is more blue. In autumn when the plant is in flower, the light is more red, because the sun is lower in the sky, and the atmosphere filters out most of the blue wavelength. This is why the plant has evolved to use more red in the flowering stage... Any questions??

If you're going to use the same fixture all the way through then what I would do is start with all veg lights. Then at around the 3rd week I'd replace 2 veg with 2 flower. 1 week later I would replace 2 more veg with 2 more flower. And then after another week go all flowering bulbs. To me that is logical...

It is! Finally some sense on this tread! Thx mate!
++ rep

 

[Mountainfarmer]

agreed! Use all 6500 for veg and 3500 for flower.

i am very curious what a person would yield on T'5 bulbs and how many plants one would get under a T 5 i use newgeneraton flours 6500 k x 2 just for cloneing thinkin it would be a waste to grow
also i use both HPS and MH lights for veg and flowering and its smokin

Yea, pretty low lumens even with 6 t5's... Would like to know how it turns out, but I'd still advise, despite my curiousity, that he get alot more lumens in there for flower time!
