250w Cfl

wavey.mofo · May 18, 2011

What is the actual wattage of a 250w cfl bulb? I've been reading that there is an actual wattage for bulbs which is what really matters, so i'm really confused.

I'll be using this in a reflector, would this be enough for 2 plants? or could i stretch it to 3 plants so i can get a larger overall yield?

I'll be growing in soil, what pot size would you guys use?

Soz for all the questions and thanks for any help given

Hmm... I've always assumed that (like home energy saving bulbs) the 250w /was/ the wattage output of the light and that that the actual power consumption wattage was less, say about 120w.

I'm most likely wrong though, I use CFL's also

If it's one of those horticulture bulbs/grow bulbs, then the 250w is actual wattage. They don't state the equivalent to incandescent on the box. If it's the big 250w bulb you get from Home Depot or where ever, then the actual wattage is something like 48w. Home Depot also sells a 300w cfl that is 64 actual watts.

edit: You'll know if it's the grow bulb because it won't fit in a regular socket.

Hmm thanks for the info but im not sure whether the bulbs im buying are horticulture bulbs.

Yes that is a grow bulb and is actually 250 watts. That's why it comes with it's own reflector, because the socket is bigger than a regular socket. You will not be able to plug that bulb into a regular light socket, it will be bigger.

however you can get larger CFL bulbs that fit in a regular house hold light socket (medium base)

i use a daylight (5000k) 105 watt for veg
and warm white (3000k) 105 watt for flower
both fit in regular socket.

phew, i'll def be getting it then. Oh yeah could someone answer my other questions plz.

wavey.mofo · May 21, 2011

Would the light be fine for 2 plants? or could i squeeze in an extra plant for more yield?

This is my second grow and its much better this time round, I have a similar 250w to the one your getting, I would say stick with the 2 plants and just train them to an even canopy, I top at the 4th node then lst the heads, I veg for about a month, starting them in 2 gal/ 8 ltr pots then in 3rd week of veg into a 4 gal/16 ltr to let it recover from stress of transplant before flowering... I use 8 week strains that usually take about 9... Pull off about 80-90g per plant.. They work pretty well, just I have a friend with a 250w hps and he out does me every time... The even canopy is crucial with CFL's as the light from them is far less effective when its not within an inch or two of the bulb

wavey.mofo · May 21, 2011

Hmmm your set up sounds good, is 80-90g your wet or dry yield? And what strain are you growing?
I'll have another 250w cfl blue which will just be hanging around the plants for extra lighting and the other 250w red spec will be in a relfector on top. This would increase my yield right? but im afraid this will fuck up the canopy since the plants will want to grow towards the other light bulb.

80 - 90g DRY per plant with a 250w CFL ?? i highly doubt that , ive been growing a while and have used CFL's myself , i also has a friend who grows with just CFL's and has done for a long time he uses 2 x 250w CFL's and grows 2 plants a time he gets about 2oz DRY a plant and he knows what he is doing ....

RobbieP · May 21, 2011

A 250w HPS in a cool tube will give off less heat then a CFL and also give you a better yield , you can pick up a 250w HPS and a cool tube off ebay for about £90 .... im not knocking CFL's as ive used them myself and had good bud and a friend of mine only uses them but just giving you a alternative

Thats 90g dry wieght, from Nirvana's Big Bud fem...

As for the blue spec 250, I heard that it would help along side a HID as supplemental lighting as you need a 2:1 ratio of red to blue light in flowering, not sure what it would do on a 1:1... Do you lst the canopy or any other techniques?

Oh i see, umm i havnt grown anything yet so i cant answer your question but im planning on topping and then lsting the tops. Hmm im gonna be growing cheese and bubblebomb so hopeguly they'll yield as good as big bud.

Schtev · May 22, 2011

Yeah thats what I do to mine, works wonders to the colas when you LST them...

wavey.mofo · May 22, 2011

Sweet, thanks for the idea, i got it from you lol

Schtev · May 22, 2011

Watch out though with the lst, the plant im growing at the moment split in the centre stem vertically from lsting too fast... Doesnt seem to have made much of a difference however, and was a pretty big split about an inch long :/

wavey.mofo · May 22, 2011

ouch, i'll probs will mess up some way or another. I was thinking of supercropping to but im not sure now. What do you think of it?

Schtev · May 22, 2011

It was my last Fem Big bud seed and a bagseed (that later turned out to be male), heres a few pics from the grow...

Pics 1+2: My grow closet, 2 plants, Big bud is the one on the left, second picture is it after it was topped...

Pics 3+4: Week before flowering, only 2 colas lst'd down to match ones around it

Pics 5+6: Week into flowering, pistils and alot more lst to even the canopy

Pics 7+8+9: Buds and Colas at week 4... No longer lsted however as I got the split at week 2 flowering

Pic 10: Shot under the light

Pic 11: Picture of the nasty split..

EDIT: Oh yea, iPhone pics
