18 autos grow

Hello guys, I'm new to the forum also to autoflowers this will be my first grow my seeds I pick are
blue mammoth 4
assassin5
5 +speed
4vertigo
i will be using 600 mh/hps 1.5 gal pots will post pics once the seeds spout.

Sounds sweet Im going to squeeze a +speed into my grow, when its done ill flip the switch and flower the photo strains that will be growing with it. That way in 4 months I get three harvests and in 6 mo ths i can get 5. So around 5 zips in 6 months in a staggered grow.

9 has turn to seedlings 7 has cracked but not seedlings yet day 5 will they turn to seedings
