Ok so my boyfriend and I are extremely new to growing and have done a lot of research and are trying to expand our knowledge everyday. As of right now we have seven early adolescent plants that are about four inches tall in this potting mix that was supposed to be mixed with regular soil [but we kind of missed that...]. We are about to transplant them into pots that have about a three-four gallon capacity and are in the process of setting up a permanent grow closet (about 9 ft high, 6 ft wide and 2 ft deep).
We went to Home Depot today and bought some soil and nutrients and were wondering if what we have is good or if we need to return to the store and exchange/return tomorrow. The soil we bought is Scotts Premium Potting Soil and the ingredients are as listed: Peat, Forest Products Compost, Sphagnum Peat, Perlite, A Wetting Agent, and Plant Food (containing .07% Nitrogen, .01% Phosphate, and .03% Soluble Potash. Before realizing that there was already Perlite and Sphagnum in it we bought a separate bag of each. Both of them are Miracle-Gro brand. The plant food we bought is Miracle-Gro water soluble All-Purpose Plant Food that has a Nitrogen-Phosphate-Potash ratio of 24:8:16.
The main question: Is the soil itself good enough or do we need to get better stuff or make our own mixture? We know that good soil is a key factor in growing good plants and although this is our first batch, a trial run, we want to get it right ASAP so our future batches will turn out GREAT!
