Key insights about video EP 02: Starting Seeds (Day 01) – How I Kratky hydroponic gardening series

🌱 The video series is about growing hydroponically using the Kratky method with limited resources and aiming to produce five heads of lettuce per week.

💡 The grower is experimenting with growing mammoth basil, which they are excited about.

💰The lettuce seeds being used are from MIgardener and are sold for a very good value of 99 cents for a thousand seeds.

💧 The grower uses a mix of tap water and reverse osmosis water for their plants, and adjusts the pH using pH down.

✂️ To save money, the grower cuts up larger rockwool cubes into quarters to fit 1-inch net cups.

👓 Safety precautions, such as wearing goggles and using gloves, are recommended when working with acids and bases.

🖊️ The grower keeps track of what they plant and when using green painters tape.
