watts per ounce?
    #5949301 - 08/09/06 11:36 PM (17 years, 7 months ago)

ok I was wondering what the minimum of watts woulds be to produce an ounce per plant, if say u had only 3 in veg and were using shoplights for veg and SL's+CFL's for flower?

would 10k to 12k of lumens be sufficient for 3 plants to grow one ounce each?

this is all speaking theoreticaly, and it tickles my interest.

I know weight really depends on how well you grow your plant, but with a fair amount of experience, some good quality soil, and your basic knowledge of pot cultivation with some supercropping and pest extras, is the 10-12k/3ounces possible?

forgot to add they are two 48" shoplights with one daylight(blue spectrum) and one sunlight(red spectrum) bulb each.

Instead of talking about watts per ounce Lets talk about it in this way: measuring grams per watt...pretty standard :wink:

Now, if we are talking about grams per watt we aren't talking about lumens, we are talking about watts.  I'll get to lumens later. 

1 gram per 1 watt is watt (chuckle) growers shoot for and is a pretty damn good yield.  A 400w light has around 55,000 lumens I think, so lets break it down to lumens...

If you get 1g/1w from a 400w light then you get 400g/55,000lumen = 1g/137.5 lumens.

If you have 10,000lumens then you'll get 10,000lumens/137.5lumens per gram so you'll get 72 grams.  divide that by 28 grams/ounce and you get 2.57 ounces.

This being said, I'll say another thing.  You need alot of practice to get 1g/1w.  Another thing to note is that growers, in general, get a better g/w ratio when they use a higher wattage light.  This is because the luminosity (lumens) is more intense (more lumens per watt in 1000w bulb than a 400w bulb), meaning more light is able to penetrate the lower growth, which makes more buds.  That being said, HID (high intensity discharge) lights are able to output more lumens per watt so they are better than shoplights or flourescents, even if the shoplights or flourescents they have a suitable spectrum for growing plants.

Conclusion, it is pretty unreasonable for a first time grower to achieve 3 ounces from a 10,000 lumen light source that is not HID.  What is the total wattage of these lights??

I hope this is a satisfactory answer.

Send back the shop lights and go with a HID massive difference like night and day. :sun:

fuck HID

lets just say that theoreticaly the people that would be growing it are poor, and can barely put dinner on the table every night even with the help of foodstamps. also one does not have a lump sum of a few hundred to spend on this. this person consumes 1 ounce per month due to quite painful issues, and cant afford his medicine anymore. 12$ a month electric for a couple of shoplights is much better than $200+ a month for 1000W HPS.

and in a dinky closet space a HPS would cause too much heat.

a shoplight fixture, 80watts and 5300 lumens worth of bulbs covering both sides of the spectrum, cost 30$.

well 2.57 ounces a month is great, and im sure i could do it.

the lumens would be flexible cause if i can find my better cfls i can crank up the lumens another 6k or so.

the shoplight bulbs are 40watt, and each fixture holds two.

This is not true HID comes in MUCH lower watts then 1000!

Use a 250 watt HID it would murder the fuck out of those fluorescent lights!

Trust me HID vs fluorescent is no match at all i have used both. If you have seen even a lower watt HID in action you would immediately know what i mean.

Growing pot under fluorescents is ALMOST worthless.

You have to understand that those shoplights only work VERY VERY VERY close to the plant as a 400 watt HID will work efficiently to almost 4 feet.

Scrap the shoplights you will be VERY dissipointed with the entire grow.

Is the 50 watts per square foot thing fairly standard? Is there any benefit to going over that?

Dude you can take the shop lights and line a closet with them put like ten bulbs in and it would be like a phototron. But the heat generated would be unberable for the plants without major ventelation.




minds eye yeah there is a benefit of going up to 60 watts. Every little bit counts.

2.57 ounces per grow cycle, which is every 3-4 months...not every month.

You are paying $30 per 80 watts of light? That's 2.67watts per dollar.  You can get a 400w hps for $140 = 2.86 watts per dollar!!

Yields on the 400w would theoretically give you 3 oz of smoke per month to burn.  Also, KwH prices in Ca (one of the most expensive places to buy electric power) are about 15 cents per KwH. 

1 month of veg (18 hours of light per day) equals:

30 days * 18 hours * .4Kw * $0.15 = $32.4

plus 60 days flower (12 hours light per day):

60 days * 12 hours * .4Kw * $0.15 = $43.2

Total run cost for 90 days of operation and a potential yield of 400 grams = $75.6.

Cost of initial system is $140.  Total cost for system and 1 run = $215.6.  I could set up month by month analysis but basically, you can get 400 grams for the price of a cheap as fuck ounce.  Then you can repeate the process for years.

Now, if you are worried about heat, think about getting a 250w hps or even lower.  I've laid out all of the information you need to calculate run cost per any system, good luck.

Also, if the USA (sucks) why are you on food stamps :rolleyes:.  If it sucks so much why are you letting the system help you.  Don't bite the hand that feeds you  :thumbdown:

Enjoy growing nothing until you change that attitude.

We grow with HID's because they work.

To answer your original question, it's not hard to get a pound from a single 600w HPS.

You shop lights might yeild an ounce of popcorn fluff buds.

man thanks for the conversions but shut the fuck up you dick, im on foodstamps cause my liver and gall bladder are failing me and im out of work, hurting, vomiting blood, and sick as fuck. I get 40% of my total nutrients, my body cant even digest rice! I cant have any oily or fatty foods so im restricted to a very expensive healthfood diet.
I have 80$ in my pocket to last me months and months and months, and whatever cash comes through is made by my GF to keep this house together.

you guys dont understand my situation, HID is out of the question, stop laughing and snarling and being a dick about it!
im hurtin an i dont care how much comes off, just asking if with proper care it was possible to gain an O per plant.
maybe ill go to hg420 where i can get some answers without getting laughed at and scolded for eating.

If your so in the hole right now, maybe you shouldn't smoke a 1/4 a week? I mean maybe just cut down a bit to save on cash, then you'll have more money for food, rent, what not. Why not just get some sort of other herb that can help you with your stress and problems? Valerian? Kava? Kratom? Seems like a lot of work for your girlfriend to support you guys (Not trying to flame you at all, please don't take it that way)


I'm here to say though to achieve any decent amount from fluoros you are going to need ATLEAST (not kidding) three of the 48" double housings that you own. Keeping the lights within an 1" or 2 to the top of the plant at all times in vegative growth (with a good fan on them to help them grow stronger and to keep the heat from getting to them) and then budding on a 12/12 for 65 (give or take) you will come out with about 3/4 oz per plant. Deffinitly not worth it (speaking from experience). After a while we added more until we had I think six or seven 48" double 40w housings which totalled around 550 - 600w total. After It was all said and done, the quality deffinitly improved with the more light. they vegged and grew overall faster, but the one thing that you can't get rid of on fluros is fluffyness. You'll have big colas that look like they will be plentiful, but will actually dry out considerably and be very airy/fluffy. With all those fluros there was probably 1oz per plant, but that is a lot of light bulbs. Don't get me wrong, there has been some terrific herb that came from fluros, but the only way to achieve denseness in your buds is to use a Sodium or other HID light, atleast during flowering. A 250w is even a great choice which will help the buds fill out MUCH better than fluros ever will.

Hope this helped!

i was considering one of those small sunburst models, i think we could get by with the two shoplights, one on each side, and a 250W above it all, or a 175W. eBay does have some nice little lights.

every morning i wake up, i feel like im gonna vomit cause my gall contracts for a while. i smoke to keep it at bay, cause the belladonna alks/phenobarbital they gave me makes me feel like even more shit, and trip out. I thought this bag of rice was my cat and I was petting it, i hate the pills. when i get back on my feet i have the opportunity to get 30$/hr running a landscaping crew, this is just to get me blazin through these rainy days.

Check out home depot for those screw in 40w Compact fluoresent bulbs. Iv used them for cacti and salvia and they work all right. What do you have for ventilation?? The Rotron Patriot is a good cheap fan dont pay more than 20 or 30 bucks for it, iv seen boxes of em at army surplus places for around a dollar a piece.
