Leromeanswered grow question 3 hours ago When growing seeds there is always genetic variation, and barneys isnt known for breeding those new hybrid strains with a great genetic stability. This means that you always have the possiblity to need to harvest one or more earlier or later than what the breeders description says. It simply doesnt match often, thats why people work with clones to make sure this doesnt happen.
This doesnt mean you shouldnt try it, just be aware of this. From the description you should be able to harvest plants from those strains together, you may need to let some plants flower a little longer than wanted or harvest some a little earlier than wanted, but most of the time its going to be a good smoke nonetheless.
Good luck!
