preparing my outdoor hole

My plants are in pots. Moved into garage during the really cool nites and spent their days in the sun. They started out really slow in growth but are looking nice now, 10-15 inches high and look healthy. When should I consider putting them into a hole and how would you guys suggest I prepare my soil with what ingredients. In the pots I had some leftover miricle organic humus, little lime pellets in bottom and small amount of 10-10-10 and perilite mix. Im wanting to get some fox farm of some sort this weekend. Which bag should I get and what would you mix in? I realize it not certain without seeing but how far off might I be from flowering stage? That is when I can determine male or female, right? They have been in pots nearly a month and looked the same after germination for a couple of weeks but are really starting to grow now.
Thanks for any insight

What are you getting the fox farm soil? nutes?

Just saw on another site, so many are really high on the fox farm and not so much favor of the miricle grow brand. What mitures would you put into the hole?

I only have the water soluable kind. I dont' know for sure if they make something you mix into the soil. Usually when I do outdoors I mix the recommended dose of blood meal a little bit of bone meal, and some peat moss. That's cause the soil is really clay like around here. I prefer using my own mix and putting it in grow bags. I dont' know if your familiar or not but they are like little trash bags that you fill with dirt. You just go to where you are going to plant...dig the hole and cut a hole in the bottom of the bag and plant. Keep you from having to go back and monitor the water for your plants since it can penetrate the soil a bit.

I use straight PRO-MIX{see gallery for pic} In burlap sac's for outdoor. The roots can penetrate threw the bottom helping to feed its self and the burlap acts like a wick sucking up the morning dew

Try one of the soil recipes from the link provided and use fox farm ferts.
