150 watt hps good for 2 plants?

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. Old glass does weird stuff, too. "Depression glass" is a good example.

But it works for you, and one can't argue with that. I've learned long ago that there's no "right' way to do it, there's only results. And if you get results, who's to say what you're doing is wrong? Not me!

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.
If you only have say 100 bucks spend it on cfl. If you can afford several hundred spend it on a hps setup. The more light the bigger the bud.

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.

Since the price of two 150w ballast is same or close to a 400 i'd lean that way.

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

HPS is the "tried & true" light of choice. It works. Very, very well. It's only downside: HEAT. If you have $$, and great ventilation, by all means go HPS. If you have even more money, use conversion bulbs and do MH daylight bulb veg & HPS bulb bud.

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.

I'm still on my first grow, so take this with a grain of salt, but we've used one 250W HPS for veg and flower with decent results so far. day # 13 of flowering right now, and these pics go up until about a week ago.

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, B
