Trying to Maximize Yield per Cost #1

Looks pretty good, just some wrinkling on the leafs. Had this with every grow and thought it was over watering. That could not be it this time so maybe its nutrient stress(?) Topping her probably next week. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 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€
