You can but what's the reason? Just make sure you clean off all the dirt off the roots or you will have trouble in hydro. PH will be bouncing all over the place. Do you have some way to measure the ph and ppm in hydro. What nutes are you planning to use?
But its still in veg right? so take some clones and root them hydro..http://www.doityourself.com/stry/transplanting-a-plant-from-soil-to-hydro
so you think i should just say fuck it and hope my boy gives me another clone of some dumpster...cause i dont wanna lose this strand and i dont wanna clone a flowering hydro plant and kill the last of my shit...and i dont want to buy seeds sounds shady....deliver it to my parents house fuck that sounds sketchy
But its still in veg right? so take some clones and root them hydro..
Even if the plant is in flower u can still take clones for the first 2-3 weeks..
And buying seeds isnt shady, its common.. And yeh i wouldntput a soil plant into hydro, good chance it'll die.
