All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight.
When it comes to lighting for your plants, it’s useful to recognize its importance by see lamps as photonic nutrients fed to plants through their leaves to power photosynthesis, the process that gives plants their growth energy.
“We engineered our LED grow lights specifically for cannabis, with wavelengths and intensity that drive photosynthesis and production to new highs,” explains Matt Johnson, co-founder of Lush Lighting. “LED grow lights are more efficient, generate less heat, and build more potency, taste and scent into your flowers.”
How far should your grow lights be from your plant canopy? It depends on the grow lights you’re using and the phase of growth your plants are in. In general, the rule is:
PAR consists of the portions of the light spectrum that are especially useful in powering photosynthesis. SCROG plants definitely love high-PAR lighting.
The energy released by burning fuel or digesting food was once energy from the sun that was captured by plants in the chemical process that forms plant matter (from air and water). (Boundary: The fact that plants capture energy from sunlight is introduced at this grade level, but details of photosynthesis are not.)
. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. (Boundary: Further details of the photosynthesis process are not taught at this grade level.)
