Those should be enough to veg 2 plants and they are 30w bulbs so you have 90 watts total
You definitely want to get something like a 150 watt hps or something soon for flowering unless you want to flower them outside.

Only do the sum of the actual watts, not the equivalent watts indicated on the box of the bulbs.
3 x 30 watt bulbs = 90 watts, not the 150 watts you mentioned (unless I'm missing some vital math skills..).
As mentioned above by budpro, 90 watts might just be sufficient to veg a couple of small plants, but that simply won't do for flowering - your plants will produce small, airy buds. You'll need at least twice that amount for a decent yield.
Also, check the color spectrum of the bulbs. Use 6400K during veg, and 2700k during flower.
Do some more research before you start your grow - it'll really help you in the long-run.

First of all Actual and equivalent watts. Equivalent is not for growers, it's for people who were used to heat bulbs to visualize how powerful is a cfl. So when you look for a cfl, don't even bother to read that 30W = 150W.
Another thing 3 x 30W is way too litle(that is what most of the people will say to you in here or any other forum).
But if you are like me, not willing to cover your area with lamps and because of space, ventilation and cost you are not willing to go for MH and HPS lamps, you can check my first grow from my signature.
I took in some thread one guys advice, his rule of thumb was 100W per first plant and add 50W per additional plant. Well this is partially true, cause it depends, how will you hang those lamps, will you train your plants, will you have 4x25W or 3x30.
So if you want to have just a simple grow, if you will train a plant to be not taller than 50-60cm and if you will switch to flower not later than 5-7weeks after seed sprouted get yourself 6-8 bulbs of 25w, or 5-6x30W and hang around those plants as close as you can, 1-3 inches is your goal you should be alright.
But a question "will 3x30w work?" cannot be answered(in most cases it won't), due to missing details like what strains do you have? what are their characteristics? how much space have you got? how much money are you willing to spend? how soon you want to harvest? how many grams you are willing to harvest, I could go on
))
EDIT: Also make sure you will buy proper color lamps: that is 2700K for flower and 6400K for veg. I saw people claiming that plant vegged alright with 5000K, but make sure you will not get 4000K, cause that is waste of electricity and plant benefits very little from it both in veg and flower periods

This comment will not have anything to do with growing.....just in case someone wants to have a smart ass comment. I just replaced my garage light. It was a 100 watt incandesent bulb and replaced with a 100w equivilant 23w cfl. Not even close to the same amount of light. I would need three of the fuckers to see anything in there. My point being equivilant wattage means absolutely nothing when it comes to growing. Always always go by true watts. I wish teachers would actually teach our kids to read and do research on there own instead of relying on other people to do it for them. Hahaha sorry for rambling im sick and had a bit of vodka to sooth my pain. Anywayz......

yes totally agree, even if they produce the same amount of light, cfl light penetration is way more worse, thats why when you hang on a ceiling you cannot see a thing and you need three of them
) There was a pic with a scale somewhere in RIU how cfl light diminishes, I cannot find the thread but I found the pic. As you can see 4 foots and you get only 1/16 haha...

Until now I never looked into HPS due to the heat output and price. I just followed your link and was wondering does it produce a lot of heat? 16k lumens and 150w consumption.. sounds so right, and comparing to 8 cfl 25watters setup it's even cheaper. I pay like 9bucks per 1 25w cfl...
but I have a limited growing space like this:
https://www.rollitup.org/attachments/grow-journals/2381423d1350842660-1st-grow-c99-200w-cfl-patalpa.jpg
its actually not the 1meter in length but 4meters, its a small room under roof, but I can make only passive ventilation I mean just circulate the air. Do you think heat can be an issue? I saw that this lamp can be 6-8" away from plant tops, so I believe that would do perfect for me, however as always, I cannot find where I could buy it in europe...

Even a 150 hps will fry your plants in a attic space if you dont have cool air flowing in. Unless the temps outside stay like 50 degrees.

It depends on the average temperature of your space.
In my attic i could probably run a 600w easy with no external cooling because its drafty and about 20 degrees F outside right now.
But if you live in a warmer climate that doesnt drop below 50 then youll need some sort of cooling.
Your room might be big enough to run it because it doesnt throw all that much heat.
Ive had 6 42w cfls in a small cabinet and they put off more heat than this little thing.
If you get a 6 inch fan and a converter from 6-4 inches like this one http://www.htgsupply.com/Files/Products/duct_reducer 6-4.jpg
You should be able to throw the heat around the room enough that it wont matter all that much.

Oh ya with temps that low im sure you would be perfect!! If you can, do it.

That's the inverse square law, it applies to all light. The reason you get greater brightness is that an incandescent is a point source of light; whereas a fluorescent is putting out light from the length of the tube.yes totally agree, even if they produce the same amount of light, cfl light penetration is way more worse, thats why when you hang on a ceiling you cannot see a thing and you need three of them

Thanks guys for pointing those things out. I decided to go for 100w hps and drop in some cfl bulbs from sides. Gonna be doing DIY reflector today. I live in Amsterdam, so weather is rather agnostic here.. neither its raining neither its sunny, or is it not? both cold and warm lol crazy climate. anyway temps in here currently is 32F outside, but in a summertime its around 70F.
EDIT: After unsuccessful attempts to get 70/100W hps ballast, I ended up with 150W.. Oh well, naking ventilation is very uncomfortable however not impossible. Hopefully my two plants will thank me

$150? That would get you:
6 42W CFLs 6500K @ $10 each 10,800 lumens

12 26W CFLs 2700K @ $30 total each 1,750 lumens

Totals: $90, about 85,000 lumens!
With the leftover $60 get bulb hangers, extension cords, remote thermometer, and fans.
The bulbs replaced each grow then can be used around the house as needed.
For small, occasional, personal use, inexpensive grows, it is hard to beat CFLs.

first of all you misread my post 150W not 150$
) I said that I was unable to find cheap ballast for 70Watt or 100Watt lamp, so I had to buy 150W ballast and HPS lamp. it costed 55eu, 29eu ballast, 14eu for the lamp, 5 for E40 socket and 9 for delivery. Reflector I am doing myself, I will adapt it for vegging with cfl and flowering with hps. so in total for those mats plus delivery is around 72$.. God damn it, here all the growers in the Netherlands seem to be industrial, cause you could get 400W/600Wbalast + lamp + reflector + socket for like 50eu haha. I miss those days when I was in US. Life seemed to be so easy ) Those links cannot be delivered outside US..
Even to get something like 8 25W cfl would cost me cheapest I could find - 70$, but only 2700K color. 6500K is another mystery.. European union regulations about 6500K color light being somewhat not proper for lightning..
Anyway NOW... since I am going to receive a 150W heater its about time to start thinking about cooler
)p.s. lol thread was started by another person in cfl grow and I turned it into my hps problem thingy, my apologies for that!
