is a 150watt hps good for 2 plants?
What kind of room you putting them in?
How long will they be in vegging?
Target at least 2000 lumes per square feet, around 4000 is what you should be giving the plant if not more. Also keep in mind that hps are good for flowering/budding and not vegging.
i beg to differ... loads of peeps use hps for the whole grow with ample success. i don't but i have friend who do. truthfully, their plants look better than mine!
to answer you q, yes it would work for two in a small reflective lined cab, but i would suggest you get another, or some cfl's. just because, ya know?
love, kp:p
Ditto to KP, except, friends plants don't look better LOL.
Adieu
bear! i just tried to email you, but your hush is no good... i'll hit you to your other in a while... as for the better looking part... 600w vs my 160w of floro's...
speaks for itself:)
love, kp:p
i used a 150hps to flower 2 plants under a screen in a 2x2x2.5 cab with excellent success my yeild was always around 5oz. i do always veg with flouros.
The light from a 150W HPS is sufficient for 2 plants from sprout to bud, provided all other requirements are met. (mylar, light distance, plant spacing, ventilation, water, etc.)
Many people switch lamps between MH or Flouro for veg, and HPS for bud. But this is not a requirement. You can do the whole cycle with HPS no problem.
i have to ask how you pulled this off, i use 2x150hps and would be happy with 5oz from the 2 combined.Quote:

heres a pic as it is right now.
veg is about 4-6 weeks and i grow scrog style. my 150hps=5oz my 400hps=14+oz. it's all about the screen! you can evenly space all budsites and keep the light nice and close to the canopy. as long as there is sufficient ventillation you can get great yeilds. power and space are my limitations so i had to find a way to get the best yeilds possible with the resources i have available. with my 400hps i get .98gm/watt and with the 150hps i get .75gm/watt that's not bad, eh?
Is that a sheet of glass that the hoods are sitting on? Is it a special type of glass, or "regular" window glass? Some of the newer window glasses reduce light - especially in the blue to ultraviolet area - significantly. I've noticed that my plants do better in direct sunshine than window sunshine.Quote:

nah i bet that glass is almost 20yrs old i found i deep in my basement and its very thin so i cant imagine it would make a big difference .
Which would make it mid 80s, or a few years after "smart" windows started coming out. :D Old glass does weird stuff, too. "Depression glass" is a good example.Quote:

But I'm still willing to wager $$ that removing it will up your growth & yield. Not a huge difference, but I think enough to notice.
well i just got my new 600CFM cage fan and i was going to rid of the glass anyways as that was keeping my temps in check, but so far so good they are growing like crazy the past few nights.
so should i get a 150w hps for 2 plants? or should i just get alot of cfls? and i get cfls what should the light spectrum be on it? 5500k?
What's your budget and work from there.Quote:

As for the spectrum around high end kelvin so 5500-6500 spectrum for vegging. Most likely just pick up a 6500 ones.
For floweirng use around 2100-2400kelvin.
If you go cfl most people switch bulbs when changing to flowering simple enough.
But I'm just a noob after all.
Work with what you can, fans and exhaust is my bottle neck right now.
I'd pick up a 400w instead of two 150w unless they have to grow in two different locations. A 400w outputs 50k lumens compared to some 16k x 2 lumens from a 150w. A 600w gives almost 100k lumens.Quote:

THAT is a hard question to answer, and is very subjective. No right or wrong answer.Quote:

CFT is the newcomer on the scene, and has only been available in the appropriate spectra and wattages over the past 2 years or so. I've seen more and more people switch to CFTs for small, enclosed spaces, and for their veg rooms. Many people are now starting to bud w/CFTs. Yields under CFT are less than yields under HPS, but still quite respectable.
CFTs become counterproductive when they're more than a foot from your plant.
go wit the hps, i get more bud from 150hps than i do with 350 watts of cfls. the bud is denser too.Quote:

we started with a lot of plants from seed and now we have 5 females left under that light. eventually we'll probably cut that down to 1-2 because of the smell. i'm happy enough with it for a first try, so I say go for it!
Volker, is this from personal experience? No matter where the info was derirved, thanks for bringing up the impact on CFT's, I'd like to know more. CFT information has seemingly been ignored since CFLs were introduced, BQuote:

so for about 70.00 i got 2 hps systems then made my own refectors, which work wonders.
2 150w HPS is enough for me to pull 1-1.5oz dried per plant up to 4 (I grow six per run, only 3-4 can mature in my space room-wise, but I could bud 5 if forced :) ) what a diff HID's make!
i would assume since i can get 5oz from 1 150hps. that with 2 in the same space ,if grown scrog style, could yeild at least 10 oz but with some practice closer to 12 oz. at least if i had 2 150hps that's what i would shoot for. i always try to get the most bud i can for the resources i have available and scrog is what does it for me. i see it as if you have 300watts you should make your goal 300grams to start and if you achieve it then the skies the limit! just my 2 cents
I don't scrog myself, I like them fallac(1 month veg 10-11 weeks flower); really, go for getting 2 150watters, I'll never again use less. I got another grow coming up, perhaps I'll log this one.
i have a 1kw cooltube in an aprox. 4.5x4.5 space that i will be up and running when my probation is over in a few months
