dump the cfl`s
buy e27 induction bulbs
40w ones are like $20 to $60 and 40w of induction matches 105w cfl`s
or you can look for a bigger lamp I see 40w to 400w induction lamps on ebay go for £10 to £100 all the time
way better than cfl`s ok for starting babies going to your local supermarket and getting some bulbs is all well and good but when its time to flower its nice to have something better
Do youre self a big solid and find a hydro store and get a full spec cfl. For what ever reason you choose this lighting media, or if your like me you thought mh or hps would be too hot for your area so you choose cfl. I was 3 weeks into flower before i bought a 125watt full spec.
And make sure its full spec. You can do it with any 1650lumn cfl from the store but you need a lot of them, and they need to be very close. If your going grocery store cfls Then mix the spec with cool/daylight and warm stay away from the 3000k color temp the plants dont need that color your best bet is 2700k (that even may be too close to 3k ) but its what i used; i hade 14 of them and some random led sticks to help with lux.
Just stay with full spec and you cant go wrong. Even in full spec; They make warm and cool color tones. (flower/veg)
Idk if youve thought about MH or HPS but i have a 600w digitial MH i paid $20 for and its 55k lumns.
Now i was told (this is untested by me ) you can run the same MH bulb throught the entire grow. It will keep your plant short and bushy with massive trich coverage. Thats what ive been reading anywayz lol.
And im not knocking the e27 indctos idk what that is this is just my advice about cfls from my own mistakes and things i wish i would have done diffrent. I spent atleast 140 on store bought cfls when i could have gotten an actual grow light for as little as $40. I got really lucky i found my MH lamp fixture at a pawn shop but i took a hudge risk on it because its not new and i including any one who worked there could give me any info on it so i took a chance and my ladies are loving it
Just tomake this reply just a bit longer, lol; have you thought about led. They make full spec and they run at a more efficent rate: Lum\lux and watts/hr.
They have a very similar cost and they can come in prebuilt unita or individuals.
Idk like i said i threw a few in as well. Including a 19watt 6500k duel tube full spec. Led i got from home depot. Its good for veg and to keep my smaller plants nodes closer together.
Or stay compact like rottedroots. Thata a decent cfl grow. Great example of how simple works.
