m0useanswered grow question a year ago They will all grow, but some of them will be different. Some may stay short other may stretch a lot. souvenir is just free or sample. Most seed banks give out freebies when you order.
I recently did an auto tent with 6 different strawberry stains and some of them where small, others tall, some bushed out, others did not. some smelly some not, It worked out well for me, but I got lucky and they all decided to go into flower aorund the same time, some of the newer autos are vegging out for 7+ weeks sometimes and that can throw a giant wrench in the cogs of the tent. You can sometimes force them into flower with stress but its not ideal.
Give it a shot and try it out. you can always use boosters for smaller plants to keep them at the same height as others, and use LST/HST to keep the really tall ones from strectching to much.
