So you're saying that the 1600 lumens light i just got is nto enough for one plant surrounded by white paper and foil? it's a 100 watt bulb because that's all they had in stock it's a CFL light....no good????

A very general rule of thumb is that your garden needs 50 watts of HID lighting per square foot of illuminated area. This rule ignores the shape of your garden, so the following is really a better guide:

A 250 watt HID will illuminate a 2' x 2' garden.
A 400 watt HID will illuminate a 3' x 3' garden.
A 600 watt HID will illuminate a 3.5' x 3.5' garden.
A 1000 watt HID will illuminate a 4' x 4' garden.

WATTAGE -- COVERAGE
1000 watt - 4 to 5 feet across (1.3 to 1.5 meters)
600 watt - 3.5 feet (1 meter)
400 watt - 2.5 possibly 3 feet (.8 to .9 m)
250 watt - 2 feet (.6-.7 m)
175 watt - small, less than 2 feet :thumbsup:

Thanks for the info so far

I said WTF cuz everyday some of my posts are erased. I posted another time on this page which took me 40 minutes to break down and it is no longer here either, any idea who is doing it, ZANDOR?

Basically it said, is 130 lumens per square foot is all you need.

A 1000watter say gets 118000 lumens produced. I cover a 100 sqft area with it. each foot thats 1180 lumens if they did not break down with distance like crazy. Since the avg area traveled is 3 feet thats 118 lumens per sqft with use of a track on less of a canopy.

Ask Zandor, if you are the only one who can erase posts, for the rest of it I dont feel like rewriting it. That is mean as hell though.

BIG DIFFERENCE!!

HID=High Intensity Discharge

HID lights that are best for growing include Mercury Halide (MH) and High Pressure Sodium (HPS).

CFLs produce a lot less lumens than HIDs, hence why they require less watts, however this is also why you need A LOT more of them to create enough light output for the plants to grow. Plenty of ppl use CFLs and Fluoro tubes to grow plants however the yield and grow time is greatly affected. (i used CFLs and fertilizers and nutrients for my 1st grow and was unsatisfied so for my 2nd grow which is in the assembly process (check out my thread) I am aiming to use HID lights and completely organic means... afterall nature knows best, not artificial.)

The other downside to HIDs are they cost much more, produce much more heat and may be harder to find (atleast in the Ontario area I have found that if i want appropriate HIDs I have to go to a hydroponics store, Home Depot and the like are no good).

Hopefully this info was useful,
Best of luck with your grow,

Karmaxul: thats really *!$% to hear that your posts are being erased, and i dont understand why someone would do that, but there might also be one other possibility... maybe your computer/internet/cookies/something isnt sending the info, that your type, properly to the website/main server...

hopefully you can get it sorted out...

heres a couple of decent lights if heat is a problem


This is the ultimate in high output fluorescent light systems, fully loaded with Max Grow compact fluorescent lamps. This makes this unit slightly more expensive than with the Envirolite version and is for the customer who requires the very best quality. Side by side results prove that plants grown under Max Grow lamps out perform all other CFLâ??s!
High output! Low heat! Low running costs!
A Fluorescent light system that allows you to grow from start to finish with just one unit!
This fully adjustable reflector allows you to start seedlings under one 115w blue lamp then as the plants grow you can adjust the size of the reflector and add in a second 115w blue lamp. This gives you the perfect amount of light for the vegetative stage of growth. Then by adding the 180w red lamp you get a total of 400w of power for superb flower growth!
-By adjusting the size of the reflector and adding in extra lamps you can grow your plants from start to finish with one light unit!
-Made in the EU.
-Worlds first CFL lamps produced specifically for plant growth.
-PCB (printed circuit board) ballasts are a special production to fit the power consumption guaranteed by Max Grow.
-High light emission, lower power consumption.
-30% saving in power!
-Low heat output means lamps can be placed directly over plants.
-Perfect for cupboard set ups and small grow rooms!
-No ballast needed! Plugs directly into wall!
-100% PAR lighting.
-Fantastic results!
-Comes complete with 2 x 115w blue Max Grow CFL lamps and 1 X 180w Red Max Grow CFL lamp.
