Is putting the plant as close to the light as possible best?

To a point depending on the type and wattage of the light source. With flourescents close as possible. HID it depends on the wattage. There is such a thing as too much light.

Yes, but temp will do more damage than lumens will good. This is why everyone charges an arm and a leg for a good air cooled reflector, cooler means closer. I use a cheap hood with a 1000 watt and my 6" exhaust hanging from the hood, and a light spreader. I am able to get within a foot to 18" from the canopy, not the 3-4' everyone on here claims.

CFL's and fluoros, as close as possible due to fast light dissipation. I even think that a couple of burned leaves from touching is better than too little light.
i can easily put my 250w hps 5inches away with no problem
maybe...the prices for cool tubes are rediculous. i bought a candle cover and zip tied it on, works great. so according to the charts i have been seeing, the closer u can get hte plant the better and bigger nug right?

ya im one of those that does 3 to 4 inches with a 100 buk hood. over priced???.... 1k hps only has max lumens to 24 inhches so each inch further is a 50% loss in lumens.
closer the better depending on heat. dont be cheep asnd buy a hood. spending the money on the room environment is where to spend it., not on seed or nutes. without a good room none of the nutes or other will do as they are suposed to do

I keep the bottom of my bonnet w/1000w/hps, four feet above my gravel and that's where it stays. My bonnet is off a crane and it has high intensity reflection. I do rows of five in my F&D table and I pull and plant a row every two weeks. I find that the smaller clones do much better when planted along side the larger plants. I also skirt my table with flouresent light tubes.

ha...whats a crane. rows of 5...1 plants under 5 lights? 4 foot away....wow. now if you had em right you could save alot of money with no extra side lighting and get more from them. maybe you find the smaller ones do better cause they are the right hight and closer to the light.

I have dutch poots meaning they are effectively adapted street lamps and the hood is so effective at pushing the light out in a fairly concentrated area that I find I get a better response from the plants when the hood is about 26+ inches away rather than closer, it's just too much light even though my temps are a constant 78-80, I have lights on during the day so the rise in temp is normal. I think a hood and it's effectiveness is quite often overlooked when discussing lights, at the heart of it is how light is delivered. Not just how big a wattage the bulb is and what sort of lumens are present at X distance away from the bulb vs. the canopy. This is still taking into account light depreciation.

It cost thirty bucks Canadian to run the lights in my budding room. I get at least a lb every month. I sell 1/4 oz of the hash I make for $100 canadian every month and that pays the op bill monthly.

I won't get into an argument here but have you ever seen a poot Medi1? I speak of the housing and ballast all in one, I suspect not but there is such a thing as light saturation even for marijuana plants.

ya well try without. no way the floiuro tubes are increasing the yield all that much..if its even noticable. wityh an intanse light in the room most plantg cant even see the extra small lumens tubes.
and a pound a month under that many light isnt verry much. i get that under 1 light. you say you have 5 in each row. and my plants are under 2 foot tall. i run had run 6 under a 1k and got 22 oz dry from that...and not a lengthy veg to get miore weight...3 weeks.
for 30 buk cdn id rather run another 600 hps.....a 1/4 oz for 100 buk???...no offence but what a rip off....to me thats crazzy costs./

I keep my bonnet at the height that I do because that is where the bonnet focuses the light on my entire grow. A crane is a machine used for building high rise buildings etc. The 1000w lights are mounted on the cranes so they can work at night. I work in construction.

i googled this poot. nothing to do with lighting came up. yes i know the style with all in 1...super hot and no good.....because of gthe heat having ballast built in.
i have tested many bulbs and set ups with a meter...a few diff meters to as most read diff.
ok i did find some sayin poot lights.. ya just a all in 1 set up. small hoods with less foot prints is what it looks like. barly big enough to cover the bulb

I run 25 clones in my system all the time. I have people begging for that chunk of cheese and down the street they can get a whole oz of bud for $175, and they know it.

you hang lights with a huge big crane...how does that fit inside a room????...so they can work at night??...mine arent on cranes and have them on at night. the pouint isnt to get the whole room lit up..its to focus on a good strong lumsnh foot print and that far away isnt a good one...its a wider one.

I thought you might have to google them, either way I'm afraid you don't know what you are talking about, certainly not from any real experience with them at least. I could tell straight away. Your assumptions of a hot old ballast and small hood that has no foot print.
Get one and then understand why this lamp is the best selling and most highly rated lamp in the horticulture industry. The ballast adds very little heat, the hood covers my 1.2x1.2m scrog more than adequately so what more can I ask for.

oh realy...i work in the horti field and we wont carry them. so to you its the best not others. of course it covers a wide erea...its not directing it down like we want cause the hood is small so light goes all over.
you could tell straight away ....lol...funny dood....so out of curiousity whats one of them cost. and by the way. i woprk also for researchers to prove or dissprove these kinda of theories.
if its so hot an item why isnt it all over the market then. i dont see any of them over here for sale in any shops
