So im wondering what the key is to getting really hard dense buds. At the moment im flowering 5 medium sized plants and 4 that flowered pretty much straight from clone(maybe 2 weeks veg). They are all the same unknown strain that ive grown before expcept for one, but the small ones have rock hard buds and have way more crystals but the larger ones have quite loose buds in comparison. Most of the buds that ive harvested havnt been very dense. Anyone know why this is or what to do get dense buds? The one on the far left is the different strain which was supposedly Hindu Kush but i dont think it is(I dont actually have a clue)(and i know it looks shit). The rest are all the same.
