Trying to Maximize Yield per Cost #1

This week I first removed two leafs that blocked the lower two nodes. After that I made sure that none of the nodes get shaded by the top with some tape. Don't think that does much but why not try it? While watering I noticed that the soil near the edge of the pot was too dry to take in any water so I watered the pot with a few liters of water. Not ideal but with the temperatures we have atm, it wasnt a problem. On Day 13 I topped the plant and added the first two stakes after another day of growth. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Set up cost (fixed costs) -Lamp: 40€ -Timer: 3,5€ -Pot: 4€ -Total fixed costs: 47,5€ Given 5 years (or 15 grows) usage time translates to around 3,17€ per grow in materials. Variable costs: -Seed: 5€ -Soil: 6€ -Fertilizer: 3,50€ -Power (100 days 20h/day): ~28,8€ (exact figure after harvest) -Total variable costs: ~43,3€ -Total costs per grow: ~46,47€
