So using this as a basis:
HOW MUCH LIGHT DO YOUR CANNABIS PLANTS REQUIRE?
HOW MUCH PAR/PPFD DO YOUR CANNABIS PLANTS REQUIRE?
- Clones and seedlings: 5,000–7,000 lux
- Vegetative growth: 15,000–50,000 lux
- Flowering: 45,000–65,000 lux
- Maximum recommended amount of light: 75,000 lux
Between 200-400 PPFD: This is great for seedlings, clones, and mother plants.
Between 400-600 PPFD: This is great for early to late stage vegging cycles.
Between 600-900 PPFD: This is great for the flowering, fruiting, or budding stage of plants.
With you lights at 18" spacing and 18" height ... a good estimate is:
800 ppfd center - bloom
500 ppfd 1' - late veg
390 ppfd 2' - early veg
250 ppfd 3' - seedlings
Let me know if you think I did this right ...
kind of, amount of lights on factors into how much ppfd you can give a plant.
40+ DLI is the approx threshold for co2 supplementation
