Question about HPS distance from plants

Check out this thread...there is a distance chart for HPS on there..the reflector on rhat light is not set-uo for air cooling, you could rig something up I guess or just buy a cool tube reflector for it.

My 600 stays about ten inches from the canopy...any closer and itll jack em up..i have a thermometer that I lay on the edge of the bucket and it tells me what its at

 

600 watts is alot different than 150 watts...check out the chart and use it as a basic guideline but like numbnutts said, you cant let them get to close to that heat, it will stress them out..but you also dont want them too far away....put them where they should be according to the chart and then hold your hand at the same distance for a few minutes...if its too hot for your hand, its too hot for your plants...adjust them accordingly if you have to.

 

Sorry im sooooo baked and didnt think of the difference....wait...i wasnt baked when I wrote that..im baked.now though...yeah a six hundred can put off like 3000 btu of heat comin off that bitch...i keep a fan blowing from the floor strait up to the light..it basicaly blows the hot air up faster so the fan can suck it out up top....and ok m lucky..i think it may be too clod in the spot without the lamp..its a solid 68 to 72 not that thats solid but you know what im saying..when I add the other six hundred tommorow I hope it raises it to 75 to 80...68 is feeling a little cold

 

^^^^ wow I am baked..sry bout the baked ramble that kinda didnt make sense.

 

And you soooo fuckin will...guaranteed..im an a.d.d. ridden person so its all that much more satisfying to finish and smoke my own...just today two of my sour d popped out the soil..

 

Hahaha! It happens to the best of us...I have a 400 watt HPS in an aircooled, sealed reflector and I still have to be careful with the heat....I wasnt baked before but I am now...fuck Its hard to type on this keypad on my phone when I get like this...it took me 5 minutes to type this shit...

 

Just watched that vid...thread ..whatever...very cool..i tied mine down a few anyway..looks very similar..i was just scared to top it that early..not now though..

Cocomoco my phone assumes it knows what I wanna say..i sent my mother a text saying I had a herbi dr apt..herbi being my grandfather...well mom dukes got a message saying I had a herpes dr apt....god damd phone....

 

I once accidently sent a picture of my weed plants to my sister, which was not cool, but that had less to do with my phone and more to do with me just being a high as hell dumbass. :

 

just laughed my ass off...

My pgone also posted pics of my garden on fucking facebook....my grandmother was like...WHAT THA HELLS WRONG WITH YOU?

 

Not to disrupt your stoned convo... Thought I'd touch on your original question...

When you plug your light in, put your hand directly under the light... so the light is shining on the back of your hand. Now, if it gets too hot, move your hand down... keep going down until it feel comfortable. Your plants should stay below that point on your light... Maybe a couple inches lower, just for safety. The problem with close distance is the heat that will destroy the plant. I don't think they can have too much light. Just too much heat.
