At the moment I'm only using two 26 watt 2700°K CFL's on a Y splitter in a clamp reflector. I bent the reflector in half to maximize reflection

yea i got one of those clamp reflectors maybe the same one. i use my 105w CFL in there i use about a total of 239w for vegg..
i have 250w MH but CFL's always showed me great results so i stick to what i know...i just use hid for flowering ..
you ever done a all CFL grow?

i was just seeing how many people use CFL's for vegg and around how many watts there using..:lol:

I use a 150w Sunleaves CFL durring the early stages of veg (2-3 weeks or so). It cuts down on energy consumption and doesn't seem to make a difference in growth (a watt saved is a watt earned):idea:

After 3 weeks, I start to train them, and switch to the 250 MH as close as I can get it.

I used to use CFL's for veg, but switched back to the T5 and my CFL's are used for germination (I've had better results at higher temps) and early seedlings (1-3 days).

However when I was using CFL's I had eight 26 watters on a power strip. I had two Y connectors connected to another Y connecter which plugged into the power strips. 4 CFL's on each, so about 200w's or so all together. I can't remember the exact number of lumens but I'm pretty sure it was around 7-8k lumens or so.

Been thinking about using them as supplemental lighting, just have to get them situated in my grow box though.... I have the CFL's in a totally different box, so it'll take a little creativity on my part lol.

I've seen great results from CFL's for bloom too, just not my cup of tea. I like good ole' Hid for flowering :hump:. I also find the CFL's work better with aero or hydroponic setups vs. soil.

what exactly are you asking im really stoned and cant translate this well haha..:dunce::dunce::bigjoint:

take cuttings before you induce flowering if you always want some plants around.. vegg the clones and before you flower take cuttings off them again.. this is a cycle ive seen lots of people use.. but im not even sure on what your asking haha

Well the thing is i wanted to just have one room and run it always at 12/12. Then i'll be starting seeds as i harvest some type of thing so i'll have a harvest every couple of weeks. I'm not sure how i could separate the veg room and the flower room in the same closet.

depending on how high your closet is you could simply build a vegg room above your flower room all you need is some lumber and B&W Poly or "Panda Plastic".. im sure you could figure something out whats your room dimensions again sorry..ill go look back to see if you posted it..:mrgreen::mrgreen:

or just build a little cab for vegging...

I haven't measured the closet. I will eventually. I have 4 g13's on 12/12 now so maybe i'll finish these so i can have something to smoke while i figure out a way to have a continuous harvest

Mindmelted is right, around 5-10 inches above the canopy.

At 5 inches the lumen output is around 50k. At 10 inches it's around 12k lumens.

You can stretch it to 6 inches to 12 inches but I only recommend that, if you have heat issues. If your environment has no issues such as heat and what not, go ahead and do the 5-10 inches.

Hope this helps some.

Hi Doobieus, you seem to know a lot about the distance between the lamp and the plant. I have the 250w(MH veg. and flower) lamp at 2-3inches away from the canopy and the temp is at most 30C(usually 26-27C canopy level), without any leaf or flower burn. Will raising the light help my grow in any way or should I just leave it the way it is. The problem was a height restriction, and to compromise I used lots of ventilation. Since this is my first grow all the help is appreciated.
strain-northern bright(nirvana) 3-4weeks flowering
lights-250w MH veg.+flower
cabinet-2x3x4.5
growth medium-soil,Ph 6.5
venting-1oscillating fan, 1fixed fan,1passive intake + 4"intake fan,one 8" exhaust fan.The lamp is also air cooled by 2 pc fans
The thermometer is one of those used for cars, and I have it taped to the lamp at canopy level

gday been at it for three months now still learning seems the learning will go on for a while, an awful lot to know. Well anyway I have two 250w hps my question is how far from bulb. How far should I be for seedlings and for mature plants for hps and how far for mh. I need help Im guessing so far been lucky.

Right now I have two girls flowering under one hps and six autos under another I split my grow tent in half with two sheets of black plastic.

30 degrees C is 86 degrees F, that's too hot, 20 degrees C (68 degrees F) low and 25.5 degrees C (78 degrees F) high.

For optimal growth with your MH 4-6 inches above the canopy for VEG, 250HPS 5-10 inches above canopy for BLOOM.

The MH has a more blue spectrum which is good for veg, the HPS has a more orange spectrum which is good for bloom. Hps can be used for veg and bloom, the MH isn't going to produce very dense buds. I'd switch it out with a HPS for better results.

The heat being to high can affect the plant's growth and stunt it as well as other things. So try 4-6 inches if it's too hot get more ventilation in there or a cool mist humidifier. If you can't get a HPS then keep that light as close as you can, that's the best I can advise.

Sorry for the novel post, but I hope this helps you. If you have any other questions feel free to ask away, that's what this club is for.
