I just want to clarify the inverse square law and where/when/how it applies. It happens to be the most sighted but least understood scientific principle on these forums. What the inverse square law says is that as light spreads in an unconfined space the light will decrease in "density"/intensity by the factor of the distance squared. The distance squared is also the size of footprint the light would produce. Now when you line the walls with a highly reflective liner, the light can nolonger spread, and as a result it cannot reduce in "density"/intensity. So in the case of growing in a confined space, the inverse square law only applies to the distance the light will travel until reaching a reflective surface + an adjustment factor based on the reflectivity % of the material. If you had 100% reflective walls it would make no difference if the light was up 3ft or 30ft.
So based on this I could have my Hps at what height and still be at moderate lighting
I have 60% reflectivity based on a study I read about reflective materials
And my walls are only 3x4 white paint

Here's 2 mothers from a breeding experiment at a little over 4 weeks.

Planted in pots outside on November 22nd and brought in on December 23rd for cloning. Temps were around mid to high 50s sometimes 60s during the day and sometimes as low as the low 40s at night. Somehow... They survived.

I dunno why you guys are giving me such a rash of shit. Do you really think I would be defending this as steadfast as I am if it didn't work? Do you think I enjoy the ridicule?

You can say what you want. You can hate the fact that you can grow plants in cold weather. Doesn't really matter because they DO!

Now I've tried to be polite and I've tried to explain. Every time I try, you guys throw science in my face like I don't know wtf you're talking about.

If I didn't know what you were talking about, if I didn't understand how the plant grows, if I didn't understand the relationship the plant shares with it's environment... How in the fuck could I grow in it?

Can you grow in 40 degree weather reliably? Can you get good results in "below optimum" temps? I do, plain and simple.

Now I've resisted the shit talking until now. I don't have any pics. I just got this phone in December. That's the only pics I've got. I try to post them every day in the thread that I linked in this thread.

You guys can either continue to shit talk for no reason at all, or you can watch the damn plants grow and form your own opinion on the subject.

That's horrible stunted growth for an outdoor plant. I live in California so I can and do grow plants in the winter too. They grow way better in the summer. That's not even debatable.

So I went and replaced a heater I was using a few times the weather dropped below 20* the problem with it was one of them infrad heater which caused a red/orange light and I had to use it in another room and push it to that room to prevent a like leak from it, now I just got a new one from walmart for $40 which now doesn't light up in any way except for a red dot which I've covered it's already increased the temp from 59* to 65* with lights off so I will monitor the progress over the next few days, it's also going to be almost 40* a few times this week
