Typically lights are quantified in watts, but is this really an accurate measure? Watts only refers to the amount of power used, not amount of light given. For example an 18W compact fluro will give about the same amount of light as a 60W incandescent.

umm, im wondering why this is happening, any some advice would be mucho appreciated, im having trouble running a timer with my ballast, i hooked it up ,an set a few cycles to see if it would work, an it turned off ok, but when it went to turn back on, the globe just flickered and didnt turn on, this also happened when i tried running the ballast off a double adapter ,and also when i tried running the ballast off an extension lead, i tried putting the timer straight in to the wall and plugging the balast in , but it would only flicked when it turned back on?, it seems like it will only work when the ballast is plugged straight in to the wall, have i got a bodgy timer? or a…

Light versus Yield

A `freind' has a 2.5 metre by 2.5 metre mesh system with 3 plants covering the entire mesh system...current yield is 3 pounds 5 ounces with 2800 watts of light and superbud....If the light was increased would there be a noticable yield difference. All the lights are above the plants.

Hey i'm gonna start growing for the first time soon and one of my concerns is light... Is HPS neccisary, or will flouros do the trick? what wattage or voltage should the flouros or HPS lights be? what is the difference between compact and non-compact flouros? i have space limitation.... QUITE a samll place, like a section of a wardrobe, so what would be less dangerous? are all hps lights pricy, or does anyone know where i can get a relatively cheap one in sydney(and if possible a few other growing supplies)? sorry i don't know anywhere but i moved here about a year ago and i only just started the whole growing thing... thanks, crzc

Just enquiring about water cooled hoods for 400w hps lighting.... Does anyone have any experience or know of any friends with experience using a water cooled hood? I've been thinking more and more about it as I have only a small amount of room to put a grow in, my last room being a small cupboard, 600mm x 600mm x 1800mm. I found that keeping the temps down in such a small space was extremely hard, to say the least! I recall that at one time in the last grow I had a small disaster, the extraction and intake fans failed! I didn't notice for only about an hour, and in that time, the entire canopy was burned brown down around 4 or 5 cm down from the tops in some places…

Okay people now i have some serious gear and need some help. I have got a 600W MH, 400W HPS and a 150W HPS. ( All this will goto a big cupborad. For the veg i plan on using the MH and the 150W HPS but they will be in a fixed postion (will be able to move up or down but no side to side). So some plants will get only MH, some will get both the HPS and MH and some only HPS. Is there anything i can do so the plants get best of the MH and the HPS. I know about those things that move the lights but as stated they are going in a cupborad. But the real question is do u think it would be better to have Just the MH for veg and the 2 HPS for the flowering. please help
