Anyone got pictures of these? Is it seriously possible to grow weed 100% soil free? My friend tells me you can tell from looking but I'm not the biggest expert (obvious) so have no clue. Would love to hear your experiences, oh gurus of the grass.
I dont have any pics, mine is a soil grow. However, yes it is completely possible and quite few people here do grow without any soil at all. Hydroponics was discovered when scientist found out that plants can get 100% of their nutrients from water. Now, you still need some type of medium or substrate for the plants to anchor their roots too, but you don't need any soil.
