If this is all the soil you have then it's fine,i only said what i said incase you had the chance to do it but it dosent really matter it just help's.
Do you kno how many hour's of direct sunlight your grow spot's get?,because they seem to love about 6 hour's of direct sunlight per day or more.
Yea man im deffinatly growing outdoor's still im just starting them off indoor's to give them some strength,i found some sick grow spot's im gonna fence of soon but i will still be growing in pot's and mayb a few in the ground.
I am using some kind of slow release fertalizer until they start to flower then move onto some miracle grow to bulk them up.
I am gonna put them out in 2-3 week's and also put them into bigger pot's before moving them into my homemeade grow bag's for flowering.
I went out again today to find another few spot's for the extra 5 i will be doing and gonna go back to it at about 4ish to see if it's still getting direct sun because i want atleast 6 hour's of direct sunlight as i think my spot's may become semi shaded by the tree's and bushe's.
Gl growing,cya soon mate
