burning

[dreadydrug]

right i got myself a metal halide lamp & the plant was about 12 days old, i kept the light about 2 inch's away from the top of the plant & i had a fan on it constantly when the light was on to keep it cool, but the plants leaves still fucking burnt & if i gota more powerful fan then it would blow the plant away, any ideas on how to keep it cool :smokin: ?

you don't put an mh bulb that close to a plant. it will burn it. mh are super fucking hot. move it to about two feet away. it may nead to be closer or further...depends on thw wattage it is.

what is the wattage?

You need a temperature probe under your light at the top of your plants. Don't let it get to hot. Using HID lights 0-12" away is all the same lumens.

its a 250W, i've pinched off the burn leaves &put it about a foot higher, it seems to have worked, it hasn't got burnt any more in about 24hours. i've also put the fan a little closer ( i havent got a grow box cos i think they limit the space, but my m8 told me i should make one, what du recon?)

Like said the light was way to close for a MH no less than 12"

If you build or buy a box, that will be much better because if not you wll loose alot of light without one..

At 12 days yes, but when it gets older you can get the light closer
