Like I said, you put some rear vents along the long side creases. Allows for rear venting of heat build up.

I was thinking about taking the plastic cover off of mine also...but will that stop pointing the light directly out the center? Or does it still work ok?....Take the plastic cover off or drill wholes??? Which is better Thanks

$13.90 on this website. Is this ideal lighting for a flowering plant? If not, what's the type of light for the $ when flowering?

Also, if you take three 200W bulbs and place them side by side, does this do any better then two 300W bulbs (if you're growing just one plant and don't need the light to span out over a wide area).

Dank, thats just the price for the bulb.. and doesnt include the ballast, igniter, and all that other shiit. The bulbs are fairly inexpensive when compared to the price of the actual lamp.

and i would say you are probably better off going with 2x300w instead of 3x200w.. because the 300w put out more lumens/w than the 200w.. or somethin like that.. but the 300w will be more energy efficient and probably not give off as much heat.

Yep... HPS is by far the best option for flowering a plant. Your second best option would be an MH argo or warm floros. The flourex bulbs are really only effective for veg growth because of their 6500k blue color, so they would be ideal if you have seperate veg and flower chambers/rooms. Oh, and I hope you realize that that price you quoted is just for the bulb. The ballast you will need to run that bulb will cost you at least USD$100.
Umm... there really aren't any 200w or 300w HPS or MH on the market. The closest comparison would be 3 - 400w and 2 - 600w bulbs. The 600's would put out a total of 162,000 mean lumens and the 400's would put out a total of only 135,000 mean lumens. Generally speaking, lights are more effecient if you use less bulbs but equivilent total wattage.

I hope this helped.

If youre refering to 2 & 300w incandescent or halogen...too hot.

dankmann,
The site that you mentioned does have good prices on ballast/socket/lamp kits ($74.90)

Generally speaking, larger lamps are better. If your grow space is long and skinny however you may get better results with 2 or 3 smaller lamps. The tradeoff is better efficiency with larger lamps VS even light distribution and the ability to get the lamps closer to your plants.

There are some circumstances in which 2 400W lamps or 4 250W lamps might outperform a single 1000W lamp. The 1KW lamp often works best with some sort of light mover whereas the 400's and 250's can be easily used in a fixed position.

If I had unlimited funds I would go for a 1KW lamp on a light mover. That would allow you to get much closer to the plant tops and give you nice even coverage.

Everythings in life is a trade off.

Peace, Harrad.

unlimited funding you say???

i think i'd get 5x 1kw HPS and 5x 1kw MH all watercooled, some nice G13 seeds, maybe some white widow.. and then go out and find myself a big bag of zoomers.. then i'd make myself a really tight aeroponic setup.. and grow some really killer buds!

peace hehe

hempgirl

can you use the 500 watt flouros in a seperate veg chamber? and would it be better then the shop lights? I have a space of 3x2 so would one be fine to grow 4 plants or more?
