Metal Halide....

Does anyone on here flower with them???if so,hows your results?I have a 400 watter and dont really have the extra green for a conversion bulb....

It will work pretty good. You are fine to flower with it.

appreciate it man,i wonder though how much different in yield though without a hps bulb???or would it really make up the difference to buy it,its like 70$

If ya have the money go for it! Ifr not the mh will do ya good.

yea,really dont have it.Has anyone on here flowered with just MH?

Think 1/3 less of a yeild

that suxx......

it would probably be better then to get it because ive got 6 beautes...

It's quite a difference. MH doesn't have strong red radiance. You could throw in some 2700k/Warm White CFLs to help boost yield and quality.

But the HPS would probably be better.

how many cfls?

Around 25-50 actual watts per square foot, seeing as they'll be used with MH.

Also prune the lower half of your plant as often as possible. This way the nutes/lights go to the colas.

2 per plant

Here's some clones flowering under a 600MH...

MH works just fine...

I think...

Those buds look ok to you???

Hell yea damn!!!

Yeah.. I think MH works ok...

MH has much more UV than most other lamps. This is great for trichrome production. While your buds won't be as big or as dense as they would with HPS, they will be the stickiest of the icky(higher quality smoke).

You obviously know more than I do...

I can buy that...

Now here I disagree with you, based on my grow...

Same strain, same res, diff light, I notice more leaf under the MH, but the buds are just as big and just as dense...

I swear to you... you may not believe me, but I have it here, side by side for several harvests now...

My MH produces just as much of the same density and size nugs as my HPS...

Which may tell you I am not getting full potential out of my HPS... and I know I have more to learn and better...

But I am still getting at least 1g/w...
