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.

haha thats my theory too atleast i think im saving energy lol..

your vegging under T5's? how many watts?

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

how far from light 250w hps to flower, also how far for conversion mh bulb to grow also mh and seedlings need help.

thanks

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.

looked at your grow with the twins did both do well

good growing to you peace bro
You're welcome and I'm not a brudda, I'm a sista lol it's cool though dude.

Both twins are doing great, feel free to join the journal if you want. The next update is this Thursday, I'm trying to update it every Thursday.
