Step 6: Introducing Plants and Prepping Medium
I will be buying plants that have already started. I want to grow herbs to start off as I love having them fresh for cooking. So obtain your plants. If you will be starting from seeds, read the next step.
A special note about Rockwool
Rockwool is made from fiberglass... So precaution must be taken. Wear a dust mask while handling and as instructed, soak the medium in water. Water keeps the fibers bound together which further reduces any inhalation risk. The risks involved are no more than handling fiberglass insulation or accessing an attic with fiberglass insulation - just wear a mask ;)
Using a pot, scoop out pot fulls of growing medium. Rockwool will shrink a little, so add a little more - you do not need this for fired clay. If you have 6 pots, take 6 pot fulls of medium and put it into a large bucket, bowl, etc. Fill this bowl with water and estimate how many gallons you added. Then measure off the appropriate amount of nutrient solution. Completely soak the medium.
While the medium is soaking, wash off all of the dirt from your plants. ALL of it - but take care not to damage the root system. Place a little bit of growing medium in the bottom of a pot, then place the plant in and fill the pot with your medium.
Put the lid on your container, and press the pot into an open hole. Repeat for the rest of your plants.
