The term means hydroponic, as in hydroponically grown weed.

There are male and female marijuana plants, when you let a male release pollen onto a female plant the female will produce seeds in her buds. If there are no male plants around the female plant will still produce her buds, but there will be no seeds inside, which gives the plant a lot more energy to produce THC. This is commonly referred to as "hydro", though to grow seedless bud you wouldn't necessarily need to use hydroponics.

Hydroponics systems work by filling a bucket filled of hydro ton (airy rock pellets) with nutrient enriched water for a few seconds every few minutes. The plant uses little energy to grow roots as it doesn't need to expand to get nutrients it needs, and can use it's energy to grow leafs and buds.
AK-47, White Widow, Black Widow, Purple Haze, are all hydroponically grown seedless bud.

Get the dro mug.
slang term for high grade weed grown without any seeds. weed grown in a hydro medium or in soil as long as its been properly cared for and the male plants have been removed the buds will grow big fat chrystal like. most of the "dro" sold on the streets hasn't necessarily been grown in a hydroponic medium, but the streets have no idea because they can't tell
I just started growing some white widow in my back yard.
oh yeah i heard thats the strongest dro on the market.
it taste better when you grow it outside, not that indoor chemical shit.

i didn't know you could grow dro outside.
you can't but as long as its a strain like white widow, northern lights, orange kush their going to call it dro no matter where i grew it at.

Although originating from the word hydroponic, marijuana no longer has to be hydroponically grown to be referred to as 'dro'. Rather, it's a general term for standard, 'good' weed, in other words that which is better than mids and schwag, but not as good as headies and crazy strains.
Yeah this is pretty good dro, I found like three seeds in the whole ounce.
