<span class="link_user">@hokus_smokus</span>, I pull clones just before I flip the veg plant. From the time the clones are taken to harvest is around 16 weeks.
The "MONSTER BUD BOOST PACK" is a great way to start with nutrients but they should give alot more X-Cell instead of the other bottles though, because you need to use X-Cell in the veg stage as well.
It's an easy autoflower to grow, I think especially fun when you're a beginner and don't have serious equipment available. The strain stays kind of small.
