Hello all! Thanks for taking the time to read this! I'm planning on getting 2 150W MH bulbs and 2 150W HPS bulbs to use in my closet grow. I've already gotten my total lumens per sq ft from both sets of bulbs but ran into watts per sq ft and confused myself haha I have 9.66 sq ft in my closet, would 2 of each bulb be enough for both veg and flower respectively for 4 plants? (I'll be using mylar and am going to build a box around them to maximize the lighting to get as much light as possible)
im my nubish opinion it is enough light for both stages , ofc flowering could use a little more to incriese yield
If you're using them all, red and blue then yes it should serve you well. 600 watts covering your area is approx. 60 watts per sq ft of adequate light spectrum and power.
