Plants and especially cannabis need most lighting during the flowering stage, so we`ll be using that as an estimate of how much area needs to be covered. A standard LED grow light must use more than 32 watts per square foot of grow space, but for optimum results it should be over 50 watts, up to 80 watts.

Also asked, how many watts do I need for 4 plants?
Recommended assuming 4.0 sq ft/plant
# of Plants | Square Feet | Wattage from Wall |
---|---|---|
2 | 8 | 240 to 300 watts |
4 | 16 | 500 to 650 watts |
6 | 24 | 700 to 860 watts |
8 | 32 | 900 to 1100 watts |
Secondly, do watts matter when growing? A good rule-of-thumb for LED grow lights is 32 watts of actual wattage per square foot of growing space for flowering medical or other large flowering plants. Low light plants, such as herbs and lettuces require about 11-18 watts per square foot of grow space.
Just so, how much area does a 1000 watt grow light cover?
7x7 feet
How many plants can I grow with a 300w LED light?
Grow Space Size | Minimum Number of Watts Required | Number of Plants You Can Grow |
---|---|---|
6 sq ft (2×3) | 300w | 1-6 plants |
9 sq ft (3×3) | 450w | 1-9 plants* |
12 sq ft (3×4) | 600w | 1-12 plants* |
16 sq ft (4×4) | 800w | 1-16 plants* |
