first big grow by twitch

Yes AND No!

Red spectrum is not NEEDED to make flowers. IT IS however a factor in the size and potency of those flowers.

ok, first off spectrum doesn't play hardly a part, if any, in flower size or potency for that matter. all spectrum is is the color temperature of the light that your bulb(s) put out.

genetics will be the biggest single factor. period. the type of light would be next, not spectrum. see your example below for more on this.

You could flower a plant under pure blue CFLs sure, but lets see you pull the same kind of weight per plant at a high red spectrum HPS.

ummmm no shit!? of course you are not gonna put on as much weight with CFLs as opposed to an HPS. not to mention wft is pure blue light. we are talking white light here, which is composed of red, orange, yellow, green, blue, indigo and violet. the blue you are referring to is COLOR SPECTRUM, or merely the temperature of white light that the bulb emits.

Are you actually saying RED has no benefit to flowering???:wtf:

i never stated such a claim. yes, the HPS will help you put on more weight during flower, HOWEVER the UV that the MH will pack on the trichs better and produce more terpins which will give you better smell/taste.

so next time before you want to try to lecture me or anyone else you might want to make sure that you have your shit straight or are prepared to take notes following the onslaught that ensues after your post. (got your pen and pad handy? well go fucking grab it!!!)

i don't need you and all of your 43 posts to cosign shit that i say. i think my rep around here speaks for itself.

vance, the red spectrum of an HPS is the natural spectrum it puts out, which is similar to the sun in the fall. the MH naturally puts out a more blue color temperature, similar to the summer days. that's all. PERIOD.

why do you suppose they sell HPS bulbs that push out more blue as FW stated? hmmmm, i wonder?


twitch, you can run a HPS the whole way. people normally due this because they can only get an HPS or MH ballast, the HPS puts on more weight in flower, so they pick that one. many get a MH conversion bulb to run in their HPS ballast for veg. (this isn't applicable for a digital or switchable ballast).

i hope that answered your question.
