later,
Been reading a bit about 'Sunstreamer' lights from the States...is it available in the UK?.....or is there an equivalent thats available. The lighting options available locally seem poor.
hey im noticing some of these compact floros are coming with digital internals now..
so the question is now how to overdrive them like their long and skinny counterparts.. I know in the early days of overdriving regular floros you would buy two fixtures and take the ballast out of one and put it in the other.. I guess here you would have to buy two bulbs then take the ballast out of one bulb and add it to the other.. net result is 1.7x brightness with very very little if any lost efficiency (it does not draw 2x the power if I understand correctly).
Worst case if you buy digitals now then when you replace them next year you can keep their ballasts and put them in new bulbs for overdrive.. in a few years you could be up to a 4x overdrive at no additional cost.
Anyone up for comments on this?? Please no "mommy said not to play with electricity" posts.. if you dont have any idea what I am talking about dont post your doomsday predictions please.. just go search and read about it here:

I just noticed for the 1st time Bob; You wired your cfl's on a board with common receptacles just like I did...Cool
I actually took all the pictures for a DIY 600wcfl board, like the ones in you piks, I used romex. I never posted, because you seemed to have a handle on the cfl crowd, and there were so many other grow issues to deal with to help take some of the load off Z...peace, lw:smokin:
uncle woody's tidbit:I added an inline receptacle box in the corner
to have a source for my little fans and/or an airpump. All in one convenient board.
NO...cfl's come in wattages from 4w to 200w, Now!:D A common 42-45w cfl you could buy at wally's for 8bucks uses 42-45 watts but give off the light of a 150watt incandescent bulb, but is cooler and uses that much less electricity.Quote:

does this answer your question?:smokin:
Aaron, you can overdrive floros, but doing it is like throw dollars by your window. Its a very expensive practice.
Floros decreases its efficiency when overdriven, near to halogens efficiency ratings, and burns very quickly. No $ at pennys...
the way i understood it..
a 2x overdrive (2 ballasts on one bulb) equals 1.7 x brightness
Since digital ballasts are built for it they automatically run at less than rated capacity (~1.7/2).
You can go up to a 4x overdrive (4 ballasts on one bulb) but this will only net a 2.4x brightness level.. same deal on ballasts.. Bulbs will last over a year.. which is about as long as you probably normally keep floros on plants.. well.. its as long as I do.. haha.. my old floros replace lights in my house and fresh ones go in the grow room.. haha
The moral of my question is.. and I dont mean to call your input BS or anything.. but where did that info come from? (note: my source is listed above).
I'd hate to lose a good idea because somebody somewhere said.. something.. there are alot of people that post bad things about overdriving floros but the ones I have spoke to in the past had virtually no basis for their negativity and had never tried it.. the ones that did do it swear by it.. anyone out there overdrivin?
hey bob just wanted to post some pics on your thread, with using cfl lights.
:thumbsup: thank you so much.... that answered it perfectly clear...Quote:

Whew! For a minute there.... I was getting ready to throw my 400HPS Hortilux in the garbage can. The tenfold results: I like that better. If you're going to be a bear!.......be a grizzly!Quote:

I've been following this thread for a while. I can't wait to read the FAQ.
hey istayblunted...you don't want to use soft white..you want to use a "cool" 6000k for veg...and a "warm" 3000orless bulb for flower...got it?...good.....
thanks man..Quote:

Hey Bob, I was thinking of getting a 200watt hydrofarm CFL Light. Well that be enough light for a grow start to finish?
i just got a cfl light today and saw instant improvement granted i was using just regular 75w bulbs and i expected improvement but not this quick it might be the ferts kickingin but i think that it was the light
Thanks ALL!!!!!!!!
just a quick question i have a few 15w cfl's that have a rating of 6500k lumens and i was wondering what equation you are using to get this figure is it, 6500k divided by 15 watts, as for me this workes out to 433.33 lumens per watt or do you use the full wattage i.e 15w =75w output, such as 6500k divided by 75 watts= which equal about 86.6 lumens per watt.Quote:

good job bob this thread and your grow logs will be the basis for my grow keep up the good work. :thumbsup:
no...your taking the color temp dividing the wattage...what you need to do is take the lumens and divide it by the wattage....2000lumens/30watts=66 something lumens per wattQuote:

SO here it is please let me know what you guys think.. Im growing in a 2ft by 2ft by 5ft space. Im using 1 105w cfl 5000k, 1 43w cfl 2700k, 4 23w cfl 2700k and 2 19w cfl 5000k. supernatural 20-20-20 supernatural 11-31-15
superthrive.. whole area is lined with mylar top to bottom.. my wuestion is should i chang these lights around . i thought of getting another 105 w and another 43w and doing away with the smaller ones or puttinf them on the sides any inputs
i say keep them all...if room permits
I have a box right now with a light T5 sunsystem 2ft 4 bulb fixture. Its working well for growing right now and the guy told me as long as I have mixed bulbs 2 red and 2 blue I should be fine for flowering as well. but I want to start another box and wanted to use Home Depot as my light source instead of 280 CAD for another T5 light.
I like the Fluros cuz the Heat factor so I wanted to use them will they be as effective as my Light from the plant store? Or should I look into getting a 150W Hps which i saw at home depot to mix with the CFLs
one more question I can use Cfls for both cycles Warm lights for flowering 2700K and Colder lights for growing? 6500K or should I keep a mix of them through both cycles? The Hps bulb is tempting and Im pretty sure It fits into a reqular socket 125V 660W As I have herd Hps is better for bigger buds. but if its going to mean more hassle from heat than I dont want to bother.
any help would be greatly appreciated. thanks

i read somewhere that if your using CFLs you shouldnt bother adding co2 because there isnt enough lumens for the plant to process it.
Is this true?
That is right. a co2 generator will not work with low intensity lighting.Quote:

This CFL light stuff seems pretty good, Nice grows BObBong :thumbsup: . I have one question for you man, What type of lights are you using? The warm, soft, or cool light CFL? I was looking almost everywhere to see if you posted it already but i couldn't find it...

That would be a VeG light man, I got my question answered and found that the Warm white lights and from flowering and The one you have now would be for VeG. I think the Warm white light could do a good veg to though :p . notorious P.O.T is only using " a daylight 42 watt cfl @ 6500 kelvin and a soft 50 watter thats at 3500 kelvin, and his grow is doing better then perfect. " I just bought one 42 watt Warm white lights @ 2700 kelvin ( I plan on getting another ) from my local home depot and One 30 watt Soft white @ 3000 kelvin I already had from lowes. I have one plant that is doing just fine @ day 16 of flowering I think. PiC at bottom... I would say all you need now is two or three 42 watt warm white lights now and you willl be on your way to growign your own bud :thumbsup: ...
Here is notorious P.O.Ts' grow : http://boards.cannabis.com/showthread.php?t=70383
I'm actually considering just growing with strictly CFL's. BobBong got a fuckin good yield. I wouldnt mind substituting a HID light with those CFL's Bob's using :).
Hey I got a question for you all. Ive done research on the net and here and found a good bulb that I can buy nearby. BTW: my plant is a seedlings at this point. The bulb is called a Philips Daylight Twist 27W ($15 w/tax for 2).
Stats:
Compact Flourscent
5000k Cool [Spectrum]
100w/27w Equivilant
Lumin = 1600
CRI: 82-83
Now the issue is that I called up their support and I mentioned that I was growing plantation and they mentioned that it wasnt suitable for growing. Something to do with wavelengths (which I thought the 5000k was for). Then she tells me they sell Incandescents that do that sort of thing. Frankly, I thinks shes dumb but I need a second option. I dont wanna plop another 15 for bulbs....
that will work for vegging.
Bob, I think you should do a grow with just CFL's and not the incandescents. I'm really curious to how it would effect the yield. Because with the yields your getting I might just grow with CFL's and might not buy a HPS. It seems less suspicious to purchase CFL's and they save electricity and from your logs they seem to give a pretty good yield.
Happy to see you are considering Converting to CompactFluorescentism :p ...Quote:

2X 85W/SPRING/65K
and then swap for these when flowering...
2X 65W/SPRING/30K 65W, 3000 Kelv
The 3000 KV bulbs are 300 watt equiv.
The 6500 are 350 watt each.
BTW... These bulbs are HUGE. Like maybe 10 inches each and 6 inch wide.
Thoughts?
seems like you are on the right track mate :thumbsup:
good luck cant wait to see a grow log :dance: :dance:
With a 350 watt cfl, how close should it be kept to the top of a baby seedling?
