Well said.
Are you a programmer?

Thanks. I fix electronics for a living. Learned a bit of c++ and java scritping just for the hell of it when i was younger, but definitely not a programmer.

Ah, makes sense.
I don't hear the word "immutable" outside of programming.

I'm just happy that there are still people with vocabularies that extend beyond what is needed to read the back of the cereal box and scream at walmart employees. Intellectual self improvement seems to frowned upon these days.

@Kingrow1 , the problem with IR when it comes from a lamp is related to the first law of thermodynamics, which you keep bringing up.

Energy that's emitted as IR is energy that could instead have been emitted as PAR. It doesn't matter how much IR comes from the sun because sunlight is free, but you pay for the energy that goes into your lamps.

Ok see my conundrum, i grow long time and study my plants reactions to everything. Now ive been through the science as best i know and i can see no real heat problem with hps.

I come on here and see that this is now a real problem but over the years i know that the quickest way to heat stress is not heat itself but overwatering or overfertilizing. These two things alone make a plant weak enough that heat stress happens even when its not hot.

I am not on either side, my problem has always been the facts that led growers have pushed here and my inability to experience the same facts in many grows over many years.

Given, when i was a noob i though i had my tent to hot, now i have it hotter and dont get heat stress because i learnt to grow healthier plants.

So i propose that the facts stand that if you give a noob with stress a weaker shitter light he will suffer less and prosper more, hence my dig at leds and not that they grow dont weed.

The facts are here, i can talk about the heat in a scientific way and work out precise levels but none are over what marijuana takes in the wild so ergo what ive proposed.

If i am wrong about the heat please explain where such an inefficent heat source like hps light can burn up a tent that has extraction because i cannot see one shred of proof and mainly i propose other stresses amplify heat tolerance of plants.

Literally i think im right here but maybe ive overlooked some part of thermodynamics or growing weed idk....

 

[Kingrow1]

You make a lot of assumptions.

Two things:
1. I grow with HID, just like you.
2. I don't give a shit about heat because it's never been an issue in my grow space.

And don't even get me started on school and science.
Given your literacy level, I'm guessing you did not attend college...

I attended school then university then i went back to college again, my literacy is very high for a dyslexic.

Now i propose you prove me wrong by science and not copy and paste led brostuff, i have started with some clear facts and question if most growers have even heat stress or just arent good enough to produce plants that can tolerate the conditions naturally found in the wild.

Its just plain and simple, scratch my head for me please dint act like im a dumbass

Prove you wrong???

What part of "I don't give a shit about heat" did you not understand?

There's no way you actually graduated...

The part of 'I dont give a shit about heat' that i give a shit about is you replying to a thread on the very same thing.

Fucking go figure greenie...!

This is why science and stuff gets left out here, look at your attitude and pompous nature, trying to win debates with your face not your brain.....

Am i on a site of noobs or you want to do some real grow stuff?

You may be the most immature person I've ever met here on RIU -- and that's saying a lot.

Ever heard of Asperger's Syndrome?
I'm pretty sure you suffer from it.

Good luck with that...

 

[Big Green Thumb]

One point you have not mentioned in your high temperatures in tent vs high temperatures outdoors in the wild is the fact the roots are in the ground outside where it is much cooler than the air temperature. In a tent, the planter, soil, and roots are going to get as hot as the air temperature. Heat the roots, hurt the plant.

 

[dubekoms]

@Kingrow1 have you ever used an led for growing?

Still avoiding the real questions for insults, i can see a lot of this is tricky for your average grower. my bad for confusing ya with science and facts...

I considered this and other such similar stresses but there was no correlation. Bar the very small pots it was hard to warm the soil by much and faced instant root rot and death as i think is a problem in a too hot a res. Mold fungus and bac. love the higher temps and showed up when soil warmed too much.

I thought the same when i first appeoached the problem as well as vpd and stuff

I think you are confusing heat with temperature. Heat is energy, measured in joules. Energy in = Energy out. When your lamp produces heat energy, or light that's not PAR, it's considered waste (because it's not PAR).. When a car engine produces heat, it's considered waste because the engine's job is to produce motion.

Sure, you might be able to make use of the waste heat if it's cold and you would have had to use a heater to get that heat. In that case, it's hard to justify a more efficient lamp.

You are a one-trick pony.

 

[Olive Drab Green]

Nope

You really should try COBs or QBs. I think you’ll probably wonder why you were so resistant to change to begin with. I know you and I don’t have great history, I’m just trying to be real with you, I think you should seriously observe COBs, QBs, or Strips in a run of your own before passing judgement on them. I think you’ll realize you should have switched a long time ago.

 

[dstroy]

Point in question, weed plants grow in climates that far exceed our tents temps and ir heat given off by the any hps.

The switch to leds negates a grower having to work to get perfect plants under hps.

I dont see how heat can build in our tents when the overall area is exhausted by high power 300-500cfm inlines, physically and thermodynamically impossible past a point.

I guess i dont want to leave this argument alone and it raises many intresting factual questions iv'e yet to see answered which leaves me to ponder myself

Just because they grow in those temps doesn't mean it's ideal for them.

Heat builds up for a lot of reasons, anything that uses power makes heat because nothing we use is 100% efficient at doing its job. Even if lights were 100% efficient at making electricity into photons, what happens to all that energy you are dumping into the system?

Do you think that the plants absorb all of the light and that's it? I can tell you right now that this assumption is false and I can prove it mathematically. This is old science too, nothing new, inklings of it happened in the 1700s and earlier.

Your grasp of basic physics leads me to believe that you don't understand all that much about thermodynamics, or what is actually happening in your tent, how much heat is generated by chemical processes. How big is the thermal reservoir in a grow space? Depends on a lot of stuff, reflectivity, transpiration surface area, media type, plant mass, etc. By thermal reservoir I mean, how much energy can be absorbed before saturation.


I don't care whether or not you like a lighting type or not, but if you are going to be negative about something, you should fucking know what you are talking about. Get smarter.
