Does the Sun's rays penetrate through clouds and/or rain?

Back round:

I have a small two month old unknown female plant about 1 foot and 1/3 tall. She has four main nodes, still developing more and small leaves forming at the nodes. and of course like about 6 fan leaves.

She sprouted up in December from the unknown seed in unknown soil but looked promising. and now shes looking good. What I've done to keep it humid and getting any sun possible is; broken three Cd's , one [two havles] secure the base and two [four havles] around the walls of the pot, and also i lined the top of the soil with foil to maximize the reflexiton, also since it was a baby i put a cd lid on it to keep it descreet and humid.
also about a weekago i broke down egg shells and bannapeels and built like a lincoln cabin around the base of the plant and topped the pot off with some supersoil - from miricale grow
[note: this is truely an experminent btw, and its working.. no signs off shock , stunted growth maybe but its good, my first baby, i just want to see it bud...]

my question is:

Does the sun still provide my plant with nuts, even when its raining and/or cloudy?

To answer this question here ya go:

When you go outside in the daytime and its cloudy, can you see anything or is it pitch black? If you can see anything the sun's light is working as it always has for billions of years. No you're not getting the brightest, most direct sunlight, but its still sunlight all the same.

If it didn't most of England would be a wasteland.

UV ray penetrate the clouds... you can get sunburned on a cloudy day depending on the index.

Natural lux from the sun on a clear sunny day is ~100,000 lux. On a cloudy overcast/rainy day it is ~10,000 lux.

Typical indoor grow light conditions provide ~5,000 lux

Not only that, but the sun is providing usable spectrum (to the plant) across the board within that 10,000-100,000 lux. Man made lights produce only a small sliver of usable spectrum within that ~5,000 lux. So the differences between sunlight and man made light is even greater than it first appears (when looking at lux). But the moral of the story is that sunlight, even on cloudy/rainy/overcast days gets the job done as far as the plant is concerned.
