Any fluorescent light will do. The light rating should be near 8000K. This is best for seedlings, clones, or anything in need of soft soft soft light. When they mature a bit bring the light rating to 6500K. 6500K will work all the way through, but to be specific...

After that, you can use anything you want.

"Red" light is used more in the plants grow than blue, in about a 2:1 ratio respectively.

OK Ive waded through the entire thread and i see you all debating the various wattage and the various lighting systems and Ive learned quite a bit about lighting spectrum of the different types of lighting fixtures and setups. but i would like to share something i have been doing for quite some time now .. i have A light ... just one single light .. well sort of a dual setup ... it is very versitile and it only cost me 56 dollars to manufacture and ill tell you first how i use it .. through the vegetative cycle i give the girls 2 months of 16/8 thich results in about a 2 foot tall plant and very bushy .. then i use the same light for the flowering cycle but i change the center bulb to a florescent black light bulb on a 12/12 schedule .. the plants finish out about 4 feet 6 inches tall and i don't really keep track becuse its all for my use but i get a pretty substancial yield off of 8 plants that usualy lasts me till my next batch is ready .. oh well on to the pix .. Hope you guys/gals like Super Skunk :)

This is the setup



Current grow in progress



Great flora penetration



Part of the last crop



Nice fat buds



so without having to have super high electric usage and without having to run hundreds of watts of power I'm still getting stoned as fuck and having a great time .. maybe some day ill go to the bigger better setups but i think id just rather build a few more fo these lights and see how far i can push it before i have to go high pressure or metal halide ..

Side Note : my camera is a older then god piece of shit 2 megapixel i bought back when 2 meg was awesome .. it now after being wet and beat up randomly puts weird date stamps and sometimes no date stamps on pix so ignore date it is not even close to actual time pix was taken

I will tell you how i think im going to do it and you tell me im right or wrong

1: a grow box i figure 2ft X 2ft X 5 ft four plants two to go to flower and two for cuttings to keep a cycle going
since i only growing here to size n cuttings figure just need a pump n drain feeder timed 3 times a day 24 hour floresant lighting and mabe up to 12 hours sodium light im going use reptile heat mat under the container for the roots and fish tank heater and pump in the feeder resovoir for warm airiated feeding

Hi everyone. I'm sort of an advanced newbie on my first grow. I have 7 moms that are between 25" & 32" and I'm about to put them into flower. I also treated the roots with Mycorrhiza so they're larger than normal and the girls are eating a lot more than normal.

I have three 400w HIDs, 2 HPSs & 1MH. Due to heat I can usually only run 2 at a time & I was planning on using the 2 HPSs for flower but I was just told that if I don't increase the lights I'll end up with about a pound between all 7 plants. Needless to say this wouldn't make me happy. I was counting on at least a half a lb per plant and I was hoping for a lb per plant.

So now I'm thinking of getting four 1,000w HPSs with cool tubes & two 500 cfm fans and I have a few questions for the experts.

1. If you had seven plants between 5' & 8', used four 1,000w HPSs to flower them, and were about to harvest. (ball park) What might you expect to get as far as dried & cured yeild?

2. Do you think four 1,000w HPSs and maybe a few 300w CFLs for under the canopy be ideal for 7 plants of that size, or do you think I should get more 1,000w bulbs?

3. Are HPSs still the best bulbs to use for flower? (I heard somewhere about a new type of HPS, possibly a one made with ceramics, that was better than the average HPS)

+rep for any & all help.

I personally think your lighting is overkill and i run CFL's for my whole grow :) .. no wattage problems no high bills .. and smoke lots of bomb ass dope :weed: .. Dude i understand your probably running that grow for distribution but you dont have to burn down your house to get killer weed .. just listen to your girls.. they will tell you what they need .. i have 8 plants under 5600k of CFL lights and they are going crazy .. Marijuana grow rooms should receive 1000-3000 lumen per square foot. Successful gardens usually are lit at around 2,000 lumen per square foot. .. here ill make it a little easier on you ill toss in a chart i go by it has helped me so i hope it will help you :)

4'FL (Cool White-40W) 2,960 1-2
8'FL (Cool White-75W) 5,800 2-4
MH 175W 14,000 5-10
MH 400W 40,000 12-20
HPS 70W 7,600 3-6
HPS 150W 16,000 6-11
HPS 400W 50,000 15-30

there ya go .. hope i helped out and didn't have to make you listen to too much dumbshit considering I'm STONED as fuck right now ...lmfaoooooooooooooo .. Peace Bro :joint: gotta go :joint:

Thanks for the help. +rep

They make up an area of about 3' x 6', they're in 10 gallon containers. And they're bushy as hell, I FIMed each of them.

By the chart you gave, two 400w HPSs would be more than enough. But I've been told by many that more light = more yeild until the clorophyl starts getting bleached out of the leaves.

Also, because of the root treatments, these girls are eating up a storm. They each sucked 5 to 6 gallons of FF Happy Frog dry in 2 weeks. I'm interested in seeing what they do when they get more light & can increase their photosynthesis.

My main concern is that the four 1,000w bulbs may not be enough even with added 300w CFLs for under the canopy.

Also, it's very crowded in there. The plants are on top of one another. I don't know this for sure, but I'd think that would increase the light requirement.

if it were me i would run 2 1000w super hps in a 3x6... but if it were me i wouldnt try to grow 8' plants indoors either.

anyhow, i dont see how you could do more than 2 1000 watt air cooled lights in such a small area (i dont think you have room for 4 reflectors and ducting in a 3x6), so i would go for 2 and 1 nice fan to cool them. and if needed, maybe some low watt/low heat side lighting as you mentioned.

i would concider the chart above as a very bare minimum... a 1000w hps for every 4x4 is usually a pretty good method for maximum results.... you can use slightly more light then that, but at some point you will run into heat issues, hot spots, leaf bleaching, ect... You can also get away with less light, it is possible to grow and flower a 10x10 canopy with one single 1000w light but quality and density will drop quite a bit and i have found that most people that have tried several lighting methods (including myself) use the 1000w per 4x4 method and in my opinion is kinda the standard set up.
