75w Hps Or 150w Hps??

I grow with a 150w HPS that I bought from RONA Ill probably switch to a 400 when I can, but for now with my little closet space the 150 is great. I vegged a single plant for a month and flowered at 2', I was amazed with the results

A true 100Watt CFL should be equal to about 400watt In lumens( what ever a 400 puts out in lumens). I myself run 2 85 watt CFL spectrum ll lights from Sunlight Manf. It says right on the box equal to 350Watts each.
No. This is wrong. Do some research and figure it out. The 400W comparison is to incandescent, not HID.

you people are all sheep........cfls are not more bang for your buck.....hid is the way to go....the amount of cfls you need to match the light output of hid is more costly to buy and opperate...and the myth that cfls run cooler than hid....b.s....sure one cfl doesnt put out much heat...but when you are shoving 12 23w cfls in a 1x1 it gets pretty warm...just as warm as the hid that is equal in power and lumens.......

don't lump me in with them, maing.

there is a time and a place for CFLs, but over 150W or so is not it. if you want to talk about what's best for 1-2 plants, that may be a conversation, but above that it's just a pointless argument ...

im telling ya.......i keep seeing these guys posting pictures of 12 or more cfls and taliking about" how much energy they are saving" and "hid is too hot i run cfls they are so much cooler...btw my temps are over 95 anyone have any ideas"...yeah cfl is great for 1 plant or a mother and clone set-up....but if you want the best bang for your buck..hid is the way to go....

I do both. 150watt HPS up top and 24 inch T5 flouros mounted vertically in each of the corners. Seems to be more than enough for one plant. I will see how it works for more plants when I start growing some flowers after this harvest. I won't be need'n for a while. I guessing 20 grams off a single lowrdyer 2.

yeah for about 3 x 1.5 i have 150W HPS + 252W fluoro, which is great.

same here...150w for 3x1.5....ive got 2 23w cfls in each corner for suplement...in the top cab.. and 150w by itself in the bottom cab....top is for scrog the bottom is for small sog from the cuttings taken from the scrog on top.....

And this is a good thing?

Use 50% more energy to get the same amount of light.

(is Microsoft involved here? yesterday's technology tomorrow)
yeah that was the point -- it's not a good thing. i think. that's what I was trying to say, anyway.

You're damned right man. You would need at least 9 23watt cfls at 1700 lumens each, which is 15,300 lumens at 207watts drain. To nearly equal a 150watt HPS HID which is 16,000 lumens. Forget about being able to position all those cfls, because you're already growing in a small cab.
Just getting all the sockets, mounting, reflectors, hangers (or single mount hanger).
Why not just go with the ready made 150watt HPs, and some a few side cfls, or forget the cfls, and go with the more efficient, powerful PL bulb setup? PL's are the new cfls. They are above 90 lux per watt. Even the more expensive cfls are under 80 lux per watt. Plus, PLs have better form factors (shapes, sizes) than cfls.:evil:

Don't get me wrong wither. I kinda dig the CFL grows too. I even like 'em more because people say "it sux" , "Can't be done" etc. I like bucking the system!

But the HIDs are still the best route on all levels. Out lay costs, running costs, temps. And they are more versital. (can relocate the ballasts to help the heat)


On the ready made 150W HPS, I gutted both of mine. They came in as vertical style. Tossed it all but the ballast, igniter and bulb/socket.

(I did keep the dome for use as a cloning dome)


(but i also wanna smoke, pay hydro less)

(I also love the experiments too!)

i just dont under stand why these guys will laydown 200 to 300 dollars for cfls and accesories and then argue they cant afford HID lighting....i mean if they would do some homework instead of reading half a cfl thread and think..."well 2 people sadi it was cheaper so thats the route ill go"...then they are on here 8 weeks later asking why their buds are so small and why the plant isnt producing as well ....or my favorite is..." my cab is way overheated..i dont know why i only have 12 23w cfls in there..so that cant be it because cfls dont give off heat"....quit being sheeple and educate yourself....

Well I don't think any CFL grow started with all the lights.

A CFL grow is very scalable.

I am on the low end of HIDs.

I started with a 60W incandescent grow bulb for a week or two on the seedling. Then 70W HPS then a 150W HPS for the rest of the veg.
Now flowering 3 plants under 2 150W HPS.

The CFL route (or mine) was no giant out lay. Sprout a seed and if it seems to be going well, add to the system. I can see the point of starting cheap to get used to growing. And build from there.

But if you are serious about growing and just starting out. Start the seeds via CFL's, if they look good get at least a 150W HPS (Deep Homo and Blowes have 'em if you don't want the mail/net ordering) before you go into flowering.

I also don't see buying high quality seeds then skimping on the lights. bag-seed, I can understand that.

Seems everyone goes balls to the wall on nutes, soil, temp, humidity, even CO2, but skimp on lights, probably the most important aspect/ingredient.

(I do wanna do a full MG soil and nutes under a CFL and see how it comes out. I bet I can do well. If its worth the effort is another story)

alright well i have some plants in flower under flourascent i want to switch to hps but i have to keep how many watts i use as low as possible.. so how many plants do you think i could flower under a 75w hps alone and how many under a 150w hps with no cfls just the hps?? thankss
Figuring out how many plants you can grow is not done by 'plants per light' so to speak, rather, you go by how big of an area your lighting can properly cover then decide how many plants you want to put in an area that size, i.e., more plants smaller or less plants bigger. (When your lighting can handle bigger plants that is, otherwise a big plant is pointless.)

A 400 watt can cover up to a 4 x 4 area although 3 x 3 would be more in line with optimum. A 150 watt covers almost nothing properly, perhaps a 1 x 1 foot space so you can imagine how many plants fit in a 1 x 1 space: 1. The 75 watt is near useless. You would need to start flowering at a very short height to ensure your light can handle the tripling in size your plant will certainly do in bloom - if not more with that light. The small plant size combined with poor lighting equals a pathetic yield, or in other words, a lot of work for very little. Incidentally, the same holds true for the 150. It cannot properly bloom a very tall plant, even 2 feet is pushing it, although the topmost part of the plant will at least give you something to smoke. For a finished height of 2 feet you need to start bloom before the plant(s) get to about 6 inches. (I strongly suspect your plants are going to more than triple though with such weak lighting, so keep it in mind when deciding when to flower.)

To optimize your lighting you should build a box of some sort and paint the insides flat white. (I would suggest mylar or another material but I am guessing cash may be an issue.) This will at least help the light you do have from 'escaping.'

If there is any way possible, you would do much better outdoors. I certainly wouldn't want to go through all that work for the little yield you can expect, but it appears people do it ... I guess you have to go with what you have, still, not for me thanks. :-)

oh there are people on here shelling out big money for cfls to start out with....

but i agree with cfls for seedlings....although sticking them on a window sill ...or in a remote part of the back yard for a couple of days is even better......

I have a 150 watter (on a hanger) for my 22 gallon rubbermaid "grow box". The usable interior is basically 1.5 sq ft. I will be using it to flower 16-20 SOG clones in double hempy cups/buckets. Depends upon the cups I can choose/afford when it's time.:evil:
