So let me get this right... If a reflector only reflects, lets say, 60% of light. It is still better to use the direct light not the direct light plus what it reflects? Doesnt seem to add up, ha

I have aluminum sheet that I plan to make the box with, mounted to plastic composite to mount everything. I have the mogule base socket for the bulb to wire up and a power cord. I think all I will need is basic wiring and hardware to mount the components. I have to buy the bulbe either way.. I...

Are you talking fisrt couple of days? If you are using fluoros and have a deficiency of light or the light is too far away, the plants will reach for the light...

I think i have decide to spend the extra $40 amd go with 1000w Hps. has anybody on here built the ballast before, im sure it is fairly straighforward..

ok thanks. thats what i thought

Here is the link hXXtp://www.1000bulbs.com/600-Watt-HPS/

Im almost positive that is a mercury vapor lamp. I bought on exactly like it for outside of my shop.

This is what I plan to buy from 1000bulbs.com. Item: b s-LU0600MT, Item: LU0600-0600T15 . My plants are vegging right now at one week under 4 Fluoros. This is about all I will need other than a socket and some wiring correct? I plan to put the light in a grow room about 3'x4'. I figure it will...

Thanks for the correction, i guess i could blame this all on THC... lol. I think i will try to go for a slightly smaller, more square room. Then put a 600W HPS in it. Thanks for clearing this up

So I am going to need about 3 1000w Hps lights to get a good yeild from the plants?

I was hoping. i calculated it out, and if i wanted 2500 lumens psf i would have to put out 300,000 lumens... A 600w hps only offers about 90000.. Im not quite sure how it all works anyways.

I am planning a new grow room. It is going to be in my bbasement, I am building a room that is 2.75' wide, 7' tall, and 6.3' long. I want to buy a HPS ballast and such, but I need to know what size I will need for the room. Will 600watt HPS be sufficient?

So do you guys think if i switched the soil now it would be worth it? I am going to get better soil tonight and things for ph. Should i just start over?

It looks as tho ill be buying some ph up and ph down, along with some better soil tonight after work. Thanks

So how do I go about lowering the ph of the water? If I leave the fan on temps go to about 65-75 degrees and the humidity drops... so im not sure about that. I think i will try to drop the ph first.

I have 2 plant that are about 3 weeks old. I also have two other plants that are 8 days old. I do not know the strain, I just picked them from a good bag of bud. Here is the problem. My plants have grown really slow th whole process. They are only a couple of inches tall and the only thing that...

I cant seen to find the answer to this question. I think it is self explanatory but i want to check. If I buy an 100W S54 HPS ballast that is quad tap, I can run four 100W bulbs??

I figured out the T stuff I need t12's for the 48" lamp I have. The lamp holds two flouros and I was looking at these lights on buylighting.com, the product # is F40T12SL. I only want the plants to be sustained for the first few weeks with this light inside a box with about 14sq feet. What do...

What flouros are best, I have acces to 48" lamps to support one plant inside? I have read alot about the lighting but am still unsure of what I will need. I want to get high output lights, should I get t5, t10, or t15's?

Yeah. Each of the lights is 20watts..
