If you are in the process of starting seeds inside, here are a few tips to make your seedlings strong and robust. There are four steps.
- Potting Mix
The more light the better. I use a shop light with four bulbs and keep the lights as close to the plants as possible. You want to give the plant as many lumens as possible. The string in the picture is a way for me to move the lights up and down.
Use an oscillating fan to blow on the seedlings. You want to exercise them by moving them back and forth to strengthen their stalks.
Add a slow release fertilizer to your potting mix. I use Osmocote Plus plus I use a 1/4 tsp water soluble fertilizer in my watering can.
I use Pro-Mix potting mix. It includes Mycorrhizal fungi which helps plant growth. They have a number of different versions, but any will do. This mix usually does not include fertilizer.
