Difference in yield between using 125w CFL or 200w CFL?

[Ajminsko]

I hope this is the right forum for my question, but if it´s not i apologize and hope for a little help from a friendly mod.
Anyway. After spending a few months reading about it I decided to launch my first grow so to speak. However I´m what you would call a "handymans worst nightmare" as practical skills are at the very bottom in my talent list. So I decided to minimize the building and go with a tent instead. As space being a major issue a 40 x 40 x 120 Jardin is all i have room for. Which leads me to my question. I´m planning on using either 125w CFL or 200W CFL for both veg and bloom and I´m therefore wondering if there´s a huge difference in the yield between the two?
Of course there are alot of other aspects affecting the harvest amount but could some kind of very rough appreciation of grams or pounds be made?
I searched but couldnt really find an answer as I suspect that any appreciation made on wattage from a HPS doesnt really apply to a CFL bulb.
Help anyone?
Thanks

125w - 200w of cfl will hopefully yield you an ounce your first go around. If you get more be happy BUT you could get less.

How many plants are we talking about?

Most first time growers could AIM FOR .5 grams per watt which would be around 60+ grams and to be honest that would be a GREAT haul for a first timer WITH cfl's in my opinion.

The watts do matter as do the light spectrum of the cfl's that you are using. What bulbs are you going with? Do you know how close you are wanting to have them to the plants? Have you thought about how long you want to let them veg?

There is a ton of cfl grows in this micro section using the 42w's and just putting a couple around the girls versus a single larger cfl light. Ends up cheaper and easier to get that light coverage ON and around them.

CFL's like the 42w's can be within inches and need to for that matter, they can grow very tight nodes which is always a great thing JUST don't veg for much or you will stretch like crazy and have airy buds on the bottom.

Estimates of yields..

no pounds brother, nothing close. I expect for a first timer you can pull maybe a zip and anything above that be happy. If you could really get it down with a 1 gram per watt that would be either 125 grams (4.4 ounces) OR 200 grams (7.14 ounces) and that would be considered HUGE YIELDS for that amount of light with a first timer grower.

All comes down to plant count, growing type, if you have read up on cfl's and how close they need to be, nutrient feedings and proper care. Then got to watch out for over watering which most growers tend to do when first starting and the dreaded cutting too early or taking "test smoke" throughout the grow.

fill us in on what sized pots, how many girls and what type of feeding you plan on using

hang the bulb vertical, suround with plants, expect around 2 oucnes atleast if u have any common sense and know how with growing. you should be able to put around 8-10 small plants around it maybe more with around 7-10 gram yeilds apeice atleast. imo-

Wow, thank you so much for the replies. You have no idea how helpful they were. Although I gotta admit I cant really give an answer to all the new questions popping up just yet.
Thing is, I started reading up on growing a few months back and only read through a few general grow guides and a few about scrog before I stumbled upon the setup and building issue. Which more or less has haunted me since then. Feels like I´ve read page after page about building, ventilation etc etc. Only to get frustrated as being handy is REALLY not my thing. Of course it´s necessary to dig through some dirt before you get to the good stuff (in this case growing). But somehow what started as an itch to grow a few plants in a really basic setup grew to massive proportions both in the economic and "tech setup" sense.
But I have to admit, when it comes to building and material I temporarily throw in the towel and go with a simple setup and start spending some of my "reading time" on the actual growing aspect.
So I´m going for the 40 jardin tent and either a 125w or 200w.
Probably 125w as I´m not sure a 200w would fit in the tent.
I was thinking about this package deal.. http://www.head-nature.com/04231
Does the kit sound reasonable or is there a better way to go?
When it all comes down to it, it´s not really a huge yield I´m after although it would be nice if I could reach somewhere around the "one ounce" area. About the "pound" thing, that was more a little mix up of measurements from my part. I´m not aiming for a small industry....

Hilbie: The vertical lamp idea sounds like a great idea.
That might even work with a 200w as the tent is 120cm tall?
I tried doing a search on the forums to see if I could find someone who tried the method and documented the process to get some more details on how to go about it. I realized though, that I had no clue what to search for. So if you have a link to a grow diary who used the method or somewhere I could get some more info on it I´d be grateful.

Thanks again!

Somehow managed to miss the vertical forum.
Thanks alot!
... Again...

There is a whole sub-forum just for vertical grows. The benefit of the vertical bulb is being able to use the whole 360 degrees of the light bulb and ditching the reflector. Some times in micro grows you can only handle so much wattage for grow lights. Growing vertical can increase your efficiency and help you keep it cooled by not trapping hot air under a reflector.
Some say their nugs are tighter when grown vertically but I don't know how true that is.

I can attest to that. I used 336Watts(12 28watt CFLs, for better light distribution rather than 1 big bulb) in a small homebuilt cab and never yielded anymore than 130 grams total dry weight!
So over .5 gram per watt would have been awesome but never did that.
Always had to keep plants no farther than 4" from bulbs.
I looked at it like this. It cost me no more than $200(bulbs included) complete for the home built box. $200 would get me MAYBE a half oz. of this quality bud on the street.
The box yielded about 4 oz, even though I was getting less than .5 grams per watt, it is still well worth the time and cost IMO.
Best of Luck with your grow bro.

one of the larger plants in the cfl box.

alot of people read doc buddz thread and beleived it, cfls are really a .5 gram per watt game at best, check beekas grow, he pulled 60 grams with 72 watts of t-8s in coco. its important to remember that alot of light from cfl never reaches your plant due to the coil design, so a 23 watt light might really be a 12 watt light that u pay for as 23 watts, meaning if the package says it puts out a 1000 lumens consider it 500 hundred, the coil design has most of the light just bouceing of itself, that why they look so bright to the eye yet when u look at your plants there not really that lit up.

Discussing yield is so counter productive because it varies so much grower to grower. IMO, a lot of people get bummed on their yields because they prefer to chop too early. Those trichs start glistening and folks get impatient, or they are looking for a racier high, and the scissors start clipping!

If you spend a lot of time looking at start to finish grow diaries, you can see what even an extra week will do for your yields! There are tons of strains out there that grow and grow, produce and produce, and then appear ready. It's no wonder in lots of strain descriptions the breeders say things like "Flowers in 9 weeks, but an extra week will really bring out the best in this bud". Patience and love will give you the best results.

That being said, there's nothing wrong at all with the single bulb CFLs... if anything else it prevents you from having to mess with any wiring Good luck!

That's a real beauty, CannaCompulsory!!!!



grams/watt is a very poor indicator for fluorescent and small HPS lights. They put out less than 1/2 the light intensity of a 600HPS.

If you compare yields interms of grams/1000 Lumens then the CFL's and small HPS lights are right in there with the big boys.

If you can grow better than 6.7 grams/1000 Lumens then you are outperforming a 600 HPS @ 1g/watt

200w cfl first grow

200w cfl first grow

hi I will be doing my first grow in a few days and ive chosen sweet tooth auto fem seeds from barneys farm due to the height and yield of the plant and quality doesn't really have to be STINKING!! as its just for myself to smoke. I will be using a 200w cfl lamp and have 2 plants in 1 gallon pots. I know it says use 2 gallon pots but im planning 2 plants and thought id give the 1 gallons a go to see if it restricts the size a tad. my space is 1 foot depth, 2 feet wide and about 5 feet high. I plan to start these seeds under a blue spec 200w cfl then after 12 days put them under the red spec with 20/4 light ratio all the way. the room is fully reflective and has a 12" oscillating fan, also im using levingtons multi purpose compost with clay pebbles for drainage. do you think expecting 3oz is abit much? anybody that could help me plz reply. p.s im using plant magic grow and bloom and I will be starting them with root stim as ive heard it works wonders for autos.
