This is my 2nd time growing. Like last time I am starting indoor and then bring my plants outside and putting them in pots. Now the pots I used last year were kept in my garage with the same soil in them that i used the last time, it was really good soil Organic n what not , treated right, put molasses in and everything. can I use that same soil for my plants this year when they are ready? Also if Im getting rid of just some what soil should I use to fill the void of emptying some out
