i like the 'how to grow weed' guide in the background, watched that manyier times
as for the hydro setup im not a expert but i know about it as im investing post harvest and it looks good man, make sure your ph is lower than it would be in soil so around 5.5 5.7 or something is ok. and make sure with your pebbles that they arent packed so tightly that roots find it harder to streth around them. thats all really looks good to me, start germing my friendd
