the only problem with black gold is knats!!! Other than that is a great old school soil. If you use ffof add some perlite to help with drainage. That stuff is good but resembles a sponge.
blue dream is tough to clone, I use an ez cloner with rooting hormone in water and still was only getting 80 % and taking two weeks. Added aquarium heater set at 79 degrees and had 55 out of sixty in little over a week. bigger stems dont clone well.
