Lighting Question

[CYRAX]

Well im getting 3 free 400 watt hps lights because they were stolen and my friend can't hold any hot items in his house anymore...

So i was wondering, why do people use weak lights during veg, then stronger lights during flowering?..

Is that a must?.. Can i just use a HPS for the whole grow?...

Thanks..

:thumbsup:

you can use HPS through out the whole grow.

by weak light, do you mean CFL?

[CYRAX]

Yes i mean CFL, why are they used in veg, and why are HPS used for flowering?..

mh for veg, hps for flower.mh emits a different spectrum of light that causes the plant to grow short and bushy which is what u want for veg and hps will flower quicker and u will get a lot better yield it also causes plants to stretch creating more room for bud growth

[dopeman420]

oh and u can use a hps for the whole grow but ur plants may stretch slightly in the vegging process im not sure if thats all right so if any one can clarify thatd be great

Well, i cant belive im saying this, but dopeman420 is right.

You can use them if you have nothing else for the whole grow.

People normally use CFL's/Mh's during veg because they have a bluer spectrum which is for vegative growth, HPS has a red spectrum for flowering.

And CFL's can do just a good a job as any MH, so they are not weak lighting.

But how come the jump in wattage, like from 400W MH to a 600 or 1000W Hps?
