MH or HPS? which do you prefer?

[Chronic Chrissy]

Personally I've only ever used a MH bulb(just picked up my fiirst HPS today yay!), so my opinion here isn't quite valid yet. But I will say that you get what you put into your plants. You can grow bud on your window sill using dirt from your backyard, but every improvement you make increases the yeild and quality of your bud. You get what you put in plain and simple, that includes lights, money, time, climate control, and most important you dedication. Balance and compinsation for short commings goes a long way.:stoned:

another point of view not yet mentioned is that mh's are much hotter than hps....making hps better for small rooms.fresh air is mandatory ,and to make my stems stronger i have a fan gently blowing them around 24/7.

So what i get from all this is that HPS is the way to go, and my buddy should figure a way to get air into the closet? what if he just opened the door to the closet nightly?

[divestoned]

not enuff to open the closet you need fresh outside air really....plants have to breathe.

what if he doesnt have a way to get fresh air into the closet? does anyone have a way to cut that corner, maybe a air purifier ar some sort of filter?

leave a fan runnin 24/7 and open a window as often as possible.......or a 4" inline fan and a length of ducting to a window....

budding mj plants love the dull orange glow of the hps more than any other lighting imo. but for veg the blinding white light of the mh is by far the best lighting. i use flouros for veg myself to conserve power so that way i can use more hps wattage to flower. i did use a 400 conversion bulb for veg 1 time rather than the usual flouros and the plants grew 5x faster under that mh than flouros but i just couldn't justify the extra energy expense as i did not need the plants to grow that fast. i grew an 8-9 week strain so there was plenty of time to veg clones while i had a crop flowering. i personally wouldn't veg with hps or flower with mh but that's just me, imo the best lighting set up would be a mh for veg and dual spectrum flowering, meaning using both mh and hps together. in the space i have available(2ftx4ft for veg 4ft7inch x 4ft7inch for flower) i would ideally like to use a 400mh for veg and a 1kw hps + 400mh for flower. and thats my $.02

Dual Spectrum rocks! Ever since changing a few years ago, I would not even consider going back, the plants love both lights/spectrums together. I have recently started to veg under CFL and tubes, seems to be working ok, albiet slow. I would like to up the size to a 600HPS for more penetration eventually, but my dual 400/400 bloomroom works great for now. Remote out the ballasts to cut down on heat. Cooltube and a good fan is a must though in my small space. Putting my hand underneath them, it feels like the HPS is hotter - but its also a larger diameter and closer to the glass then the MH. By rule of thumb, MH should be hotter at = wattage

HIPROGLOW...not sure but I think that was perhaps abit of attitude their about my responce. My maybe you misunderstood me, so I'll spell it out in simpler terms....
MH
veg. cycle= good/great
bloom cycle= ?...heard rumors
HPS
veg.cycle=fair/great
bloom cycle=good/great
Now if I remeber right the man asked for the reason why you like your choice of bulb. Maybe I throw you off when I included my 2 pennys worth of info on CFL's. However maybe I didn't get to discriptive enough for ya and left ya to few words to put it all together. Not sure?
Thats my bad brotha...
I keep forgetin ya have to be damn near pollictically(sp?) correct now a days.
I thought since this forum is closet/cab. that maybe my responce would have been helpfull. But since you want to try and pick me apart well...I'd have to step aside for a moment a say big %&ck you to your math!
I seen/done/read cultivators flowering lets say....400w..9 plants in a 3x3 area...thats pretty fair right...over kill IMO?
You can figure that 8 weeks from now you'll be seating the next batch, which means you'll have plenty of time to clone, and get some establishment.
So with this in mind....where and why the fuck would you want to have a veg area suited for a MH? Again...we are in the closet/cab. forum right?
A switchable might be his best bet for his space....i dunno.
Maybe this conversation will shed some light for GROWDATPURP.
Perhaps Growing-by-numbers will suit him/her just fine.....I'm just an old guy....what the fuck do i know? It's hard enough tryin to keep up. Peace:stoned:
