How long does it take for white widow to fully grow in soil with vermiculite?

Any ideas on how I can make my garden a success story?

I'm already using plant food spikes 13-4-5

Well as for the title question if your growing them big somewhere between 7-10 weeks but if your doing a SOG somewhere between 5-7 weeks, as for how to make your grow a "success story" there are so many other factors that would have to be considered before we could even begin to help you, like setup, lights, nutes, medium, ventilation, temps, etc. For us to be able to really help someone they first need to post as much relevant information about their setup as possible, I mean its like me asking "how long would it take you to paint my house" but not show you a picture of my house, lol. I'm truly not trying to be a dick here but come on man, give us something to work with, lol.
