I got either a crazy or smart idea, growing aquarium plants for some extra money. To increase the amount of plants I can grow/propagate, I can put some species(anubias) in closed moist containers under bright lights because co2 in the air. For other plants I can put them in tanks with water and a dirt/sand substrate, under a light for maximum growth. Using the cheapest/most effective lights, foam and lead plants weights to hold stems in place, pots and “plant wool” for other plants, to make the profit of plants greater than what I spend a possible way of making some extra money. Around $100s a month possibly and using eBay to sell them, not an actual job, just some extra money that I can earn in my free time. Would this work, selling plants in high demand and using eBay, or would I barely get anything out of this besides losing money or gaining only a few bucks?
