Grow room environment is key to growing a successful crop, time after time. About 85% of the battle isn't the nutrient brand, how much to water, or pot size, it's the climate that you create to grow within. Good air exchange and circulation keeps the atmosphere fresh and clean, making it less hard for your plants to thrive whilst also helping to keep the pests at bay. in order to remove odour, humidity and heat from your room, a series of good inline fans and carbon filters are needed. Once you have the environment right, that's when you can focus on the road ahead.
