adaptation to environment

Got what I think is a good question here.

Here is what I have done and researched. First, I am using Jethros plans with a few mods. I have set it up in my closet, and unfortunately that is not where I would like to have it, but its all I can do, so I have to go with that and it cant be changed. My house is pushing 50 years old and the house just does not have air circulation like the newer homes do. It is a tri-level and between the lowest floor and up to the top floor, there is always at least a 7 degree difference and season makes no difference. There is something else I cannot change.

Now, when it is 70 downstairs it is at least 77 in my bedroom. I wish my bedroom was downstairs; see my dilemma? Put into a consideration of my plant being in a closet, with the doors partially open, a blanket over it to hide light leaks and the lights of 8 cfl 23 watters and at 1600 lumens each.

I have seen this box reach 108 degrees. As I wright this, it is actually 77 degrees in my room and inside of the box is 93 degrees. Just to help cool it, I tried putting a fan inside to move the air around. Thats when it hit 108. It was a 7 inch clip on fan and it just recirculated the hot air inside, probably to big of a fan. So I removed the fan and put a frozen 2 liter bottle of water in there and that is why it appears to be at 93 degrees now. I am going to place another bottle or two of ice in there if this seems to be working. Maybe I'll put the fan back in if I can get it to all fit. There is already a 2-liter of yeast/sugar/water in there as well. The real estate on the bottom would be running out real quick when I start lowering the plants.

I have considered that the sun puts out 10,000 lumens(these plants grow wild in this condition all over the world with this) and doing the math I have 12,800 lumens. I have posted this question before and the consensus was to not remove the light. Along with not removing lights, the best answer was to just lower the temp, which makes a lot of sense. Why cant I remove some bulbs to decrease the heat some while still providing adequate light? It seems to reason that it is possible to have too much light when you have a heat problem. According to my research I could take a couple out.

Sorry this is long winded, but my question totally revolves around these circumstances that I have to work with. I am adapting.

Considering the fact I know I dont have an "ideal" environment. I understand that this creates stress for the plant and cause males or hermies. I dont want either at all, ever. My plan is to ultimately keep a mother to clone off of, I am only wanting 2 plants at the most at any given time.

You can see that I am still experimenting with cooling the box as much as I can that stays within my limitations of "my" environment. My question is this. Can the plant adapt to its environment? It will be constant, I believe I can keep it reasonably consistent even though its not "ideal". My thinking is it can adapt, it would have to for its own survival, ultimately getting stronger. Or, am I just spinning my wheels doing this and never getting good yields for the effort I put into it?

Please, not to be rude or anything, but I would like advice from people that has "been there done that" before kind of advice I am seeking and certainly from people that has grown in all different environments.

Thanks all...

the plant could survive and such and yes be stress.. but adaptation or.. evolution through darwinism isnt something that can be accomplished by one generation... meaning that they would never really adapt. the adaptation would come after the plants that were more readily able to survive in the environment and breed till the plants that are more ready to survive in high heat environments would thrive and out flourish the other less adapted plants... follow?

Survival of the fittest....Gotcha.

indeed sir

Ok, with that said. This being my first grow, I dont have high expectations. My thinking is that start with what I have, let it flower and harvest, then take a cutting and start a clone, and keep with that cycle each time. Do you see that theory being plausible? Would that in fact over time create a stronger plant for the environment, or would I need to breed it continuously until if at all it adapted to this environment?

i dont know for sure but from what i know since a clone is genetically the same... it wouldnt change but i say hey go through with it and if you are satisfied with what you get do it again .. i mean i doubt your shooting for a huge 1 plant harvest. so i believe it may work for you.. ive also heard of a strain that can grow in the deserts in the western usa .. not sure what strain that is.. but if it interests you, you should look into it.

No, that's not how it works at all. I'm not a marijuana-growing expert, but I do have some basic knowledge of genetics. If you're looking for plants to genetically adapt to their environment, you're going to have to *breed* plants, and a lot more than two at a time also!!!!

Now let's say you have 100 plants, and out of that 100, 2 of them has a gene which creates a plant that is particularly adept at surviving in a very hot climate. So, let's say these 2 plants have a 100% chance at surviving and reproducing in 100+ degree weather, while all the other plants only have a 25% chance.

Now, let's say (for the sake of simplification) that this gene follows a classic dominant/recessive gene pattern, and that this particular gene is dominant (for the sake of easier math, this is all hypothetical).

So, that means out of 100 plants, the 2 plants with the gene, plus 0.25 * 98 = 24.5 plants without the gene survive, and reproduce with each other, creating 100 seeds which turn into 100 plants. Now, let's assume that the pollen spreads evenly, so Out of these 100 plants, 0.75 * (2/26.5) * 100 = 5.66 plants now who exhibit the trait of 100% survival in 100+ degree temperatures, and the remaining 94.34 plants do not.

That means, in the next generation those 5.66 plants as well as 0.25 * 94.34 = 23.59 plants without the gene survive and reproduce creating 100 seeds which turn into 100 plants. Once again assuming a equal, proportionate pollen distribution, 0.75 * (5.66/29.25) * 100 = 14.51 plants which possess the trait of being able to survive and reproduce in 100+ degree weather.

As you can see, in each generation of my highly simplified example, more and more plants possess the favourable trait of being able to survive and reproduce in 100+ degree weather. So, through the course of many, many generations, almost all of the plants come to have the gene which enables survival in 100+ degree weather.

However, growing only two plants and then taking clones is not going to change the basic DNA of the plant which is going to stay the same. If the mother was ill-suited to growing in high temperatures, all of the clones, and clones of clones are also going to be ill-suited to growing in high temperatures, regardless of how many generations of clones you take.

Thanks for the very detailed answer. I actually get it. I did not expect my plan to work the way I was hoping and what you stated clears it up for me. I am going to have to research other options, I would really like to get the temp down but I have just about exhausted all my options.

I love how that is almost exactly what i said just more long winded lol

I got it, kudos to both of you. Thanks.

any time man good luck with your grow.
