Hello guys!let's say i wanna grow some weed with a ventilator a light bulb and some fertilizer and water of course.How much thc content will my weed have?I know i woudn't be really strong weed but i'm wondering if it will be shitty weed.Sorry if it's a stupid question

Shit loads, maybe more it depends on the day and what you had for lunch.

While you've made no mention of a towel, the answer still comes out to 42.

Sometimes I swear these newbies are trolling. Why the heck is this even in DIY?
