When your dirt gets exposed to light.. weird shit will grow in it..

If "weird shit" is not sufficient for you, then I am sure KARMA will give you more details... LOL..

Either way, you do not want weird shit growing in your soil..

NOW here is the controversy.. many many people say that roots do not want light exposure... and I agree 100% expect...

Every once in awhile somebody will post some pictures of some amazing plants.. both Hydro and dirt.. and the roots of these plants will be exposed to lights...

GO figure...

i love you
