— What happens if you spray plants under full intensity LED lights?
Never spray under full intensity LEDs. Here’s why. 🌿💦
Dim to 25% first. Spray in morning light. Let them dry. Then bring back up to 50%. That’s the protocol — and it mirrors exactly what happens outdoors. Nobody sprays crops at noon in August heat. You spray at dawn when the light is soft.
Morning light awareness. That’s the grow tip most people skip.
