back to article Grow-lamps roast Yorkshire dope farmer in his sleep

A West Yorkshire cannabis grower died of hyperthermia after halogen lamps in his illicit indoor dope plantation heated his house to a fatal 38°C, the Sun reports. Luke Holmes, 28, constructed "three foil-lined tents each containing marijuana plants", nurtured by a "battery" of halogens. He died in bed and was discovered by …

A fatal 38°C?

If you think that's fatal, you'd better not visit Australia. I don't think those police officers would last long here in Melbourne, Last summer I recorded 48°C one afternoon, and it was in the high 30's all week.. Now that's HOT. By the way, we didn't have air con in our house (Air con is for wimps).

Flames because... well, if you've experienced an Australian summer, you'd understand.

It depends on humidity

I experienced near 50 degrees C in the Negev desert, but because the humidity was in single figures, your body can get rid of excess heat through sweating. If the humidity is too high, you cannot release the excess heat, your body temperature exceeds 42 deg and you die.

Divers in certain areas carry alarms to tell them the water is above 37 deg C for this reason

er you can't die at 38C no way

Middle east and even Mediterranean countries routinely hit temperatures above that ... never heard of them dropping dead... that temperature can't be right..

Agreed. I was strolling around Sevilla at 37C last year and don't recall dying.

Peak vs constant and humidity

The problem with the lights scenario is that the temperature will be constant - no matter the time of day the temp will be 38 deg (or higher).

Normally a body gets to cool down at night. If the temperature never gets below a certain level (I think it's 24 degC) then the body will eventually overheat.

There is also the matter of humidity - if the air is dry and very hot a body can sweat to keep itself cool - if the air is hot and humid then the body cannot cool itself.

Take a trip to Rio de Janeiro in the summer

It's not only hot - the hummidity is extremely high. It's quite normal to get a full week of 32 - 36 C, and more than 90% of relative hummidity on the air. Try sweating away the heat on these conditions...

You open the cold water on the shower, and it's warm. You think "Duh, I hited the warm tap!". And, no. It's the cold tap that's warm. The warm would burn You. :P

So You take your cold (but hot) shower. You dry yourself up, and put some clothes. And then it's time to work.

15 minutes later there's sweat running down your spine. Your armpits are totally soaked, and You need to take another bath.

Dying of 38C INHOUSE? There's something wrong. He could step out any time. No one in his right mind would go trough this when the street is much cooler and at one doorstep away.

Heat balance

It's all down to the heat balance of the body. IIRC from my biology days the human body spends less and less energy to keep warm up to around 31 or 32 C. After that the body starts spending more and more energy to get rid of excess heat (pumping more blood to the skin kinda stuff). 38 C skin temp and 100% humidity means there's no way to dump heat and the core temperature rises to fatal levels (skin temp is a lot less than core temp). 38 C core temp is a mild fever, 42 C is not.

I wonder

Why your average grower doesn't use LED lighting (perhaps with some form of small heater for temperature control) to reduce the heat (and wattage) output, which would keep the anomalous power usage down.

Because..

Per lumen, LEDs are horrendously, ridiculously expensive. Also, far easier for your illegal grower to shimmy up a lamp post and swipe the friggin' massive sodium halide, than spend all year nicking hyperbrights from the back of buses and the wheel hubs of poser bicyclists.

LED Lights

I keep marine fish, I am looking to get LED lighting the next time I need to replace my existing lights, they're very expensive. Also, the leccy used by bog standard halogen lamps isn't an issue for your average cannabis farm what with bypassing the meter.

hmmmm

its not just about brightness its about the levels of light that plants need at certain times of the year (blue and red light to put in laymans terms)

you cant use normal incandescent lighting or halogens. it needs to be HPS (high pressure sodium) etc.

just because a room seems light to us, doesnt mean its getting the quality of light to be able to produce flowers (the buds that you smoke)

Other sources output more lumens

But you can presumably place the LED lamps close to the plants due to their lower heat output

38 degrees, although hot, is not THAT hot.... I've been in hotter temperatures in Portugal. Admittedly I did get heat stroke on that particular occasion.

Given a yield of 5 oz per plant (not unrealistic, and possibly a bit conservative), and a potential market price of anything from £120 to £250 per oz, are your orchids really that good?

38c

Umm, actually you can die of that temperature. Whilst many parts of the world do get hotter than that quite often (I have seen 50c in Saudi) the point is that he was exposed to 38c for a long period. He will have dehydrated quite rapidly and quietly passed away whereas those who have experienced those 38c or higher temperatures who have gone into the shade or an air-conditioned indoors and had nice long cool drinks will tend to survive.

Re:38C

The quoted figures (38C, 50C etc) *is* the shade temperature. Open sun desert temperatures can be 70C+ (158F+). The highest Saudi shade temperature recorded is a lovely 58C (137F).

Grow Lamps?

Erm, these are not grow lamps - Halogen lamps are pretty much useless for growing marijuana - they don't produce the correct spectrum of light and they are far too hot. High Pressure Sodium is the lamp of choice for such activities or if you can't manage that flourescents work but are not as effective (great for the vegetation stage but crap for flowering) - so basically the guy was an idiot.

Also foil is not recommended either, it creates "hot spots" which can fry the plants - mylar is the material of choice.

or so I have heard...

I've seen 'Saving Grace' and she showed no signs of suffering adverse symptoms. Probably as much caused by dehydration as anything heat-related.

Anyway, as any fule kno dope grows best at 30 degrees. Leastways, it does in my greenho....oh, damn. Charles, get the rifle out. We're being phucked.

It won't be the heat that killed him

it will be the humidity. At 38 degrees celsius the atmosphere can hold around 50 grams H20 per kilogram of air or 70% relative humidity.

A Humidex of 54 or more i.e. 38 degrees and 60% relative humidity would indicate that a heat stroke is imminent.

Probably guessing the temperature, anyway he's dead (about a year ago)

Inquest presumably delayed for police inquiries?

A story online from the Halifax Courier, which might be the origin of The Sun's, seems to be unavailable except for instance in Google's cache ("luke holmes" hyperthermia). That version does not put a figure on the temperature. Notwithstanding the story may have been withdrawn for possible errors, apparently a friend broke into the house using a ladder and, presumably, a window, which would cool things off a bit by the time the ambulance or police arrived, which might not have been straight away. And taking the room temperature might not have been the first thought. I suppose he may have had his own thermometers but an ordinary room thermometer isn't particularly accurate - mine don't match (I have indoor/outdoor thermometers attached to fridge and freezer with the "outdoor" probe in the cool compartment). And according to a recent UK TV documentary, for several reasons when police find an indoor cannabis farm they don't switch off the lamps straight away, but the friend may have done.

Further speculation would be rather disgusting. But while some people do indeed survive temperatures above 37 degrees Celsius, many don't, and taking alcohol or other recreational drugs that affect temperature regulation may be dangerous.

So what have we learned... put the cannabis plants upstairs and sleep in the basement? But bear in mind that the police use helicopters with thermal cameras, they'll find the stuff... too bad that they didn't get around to this fellow before he croaked.

But it's quite hard to die of dehydration in one single night

He may have died of dehydration. It's quite likely, in fact. But I can't see how one could die in just one night (You said we can't drink water sleeping - tht's where I got one night from). We have more than enough water to withstand a single night of 38C.

Yes, yes. You can always dehydrate over a couple of days. But then it wouldn't be a matter of drinking water while asleep, would it?

Legal Plants?

If one is growing legal plants for resale, one has to do other things legally.

Like pay for the electricity you're using to grow them. Like have a business license for one's greenhouse, and locate it out of town where the zoning bylaws allow that sort of thing.

And if your business is legal, you will, of course, have plenty of competitors who can grow what you're growing at the same cost you're paying. So it doesn't surprise me that people are growing marijuana instead of attempting to meet the demand for other more legitimate horticultural products; those who are professionals in the greenhouse business will handle growing the orchids for which there is a demand, and your typical grow-op operator would not have the competency to survive in competition with those professionals.

Halogen lamps?

Are you sure he used halogen lamps? That would be the stupidest way to grow indoors. Too inefficient. But i doubt a sun 'journalist' would know any more than that it was a light bulb.

If you want to tinker with growing, then the cheap and nasty way is to use a few CFL's.

Anyone half-serious will get either a high pressure sodium lamp, or metal halide lamp, or both for larger setups. You need these to approach outdoor daylight light levels indoors.

LED's are still mostly too shit / way too expensive for growing, although research is progressing into this. It holds the promise of combining several different types of narrow-band coloured LED's to target the specific wavelengths needed by the plant.

BTW, most growers are honest enough to pay for their own electricity.
