Lowest heat production for a small tent

What I am saying is that you need to consider the energy stored/released from the plant when it is burned. That amount of energy needs to come from somewhere.

I guess I'm just not smart enough to to see how that's relevant

The relevance is where does the plant come from? It requires energy from some source to maintain the chemical reactions that actually produce the physical structure. If we add energy to a space it will raise the temp. a fixed amount-that's simple physics. Watts and BTU are the same-they are just units of measure for energy. My question is if (X) amount of watts(BTU) are introduced into a space, aren't a percentage of those watts used to actually grow the plant rather than heat the space?

Just my .02: i currently flower in a 2x4x6 tent running 600w advanced platinum led's 2 p150 units and a p300, i draw my intake from outdoors and run lights during night, tents max temp on average is 75-77, on rare occasion it will hit 80-81 but thats usually during summer months, ive never bothered to really measure how much heat the lights put out but ive obviously got my stuff dialed in cuz ive got no real heat issues..

I am playing with fan and lighting. I have the light at 150 watts right now and the fan on 60 volts (half) and I hit a peak of 83F. 150 watts in that tiny tent may be plenty anyway it is really bright in there. Very reflective interior (that hammered mylar stuff). If i crank the fan the air intake gets loud. I might have to make some intake adjustments to see if i can get to 200 watts with the light.
