In early growth, a heavy dose of deep red and infrared encourages plants to stretch — they reach for the light and end up tall, leggy and weak-stemmed. Later on, when the plant is setting flower or fruit, that same deep red is exactly what you want, because it's the part of the spectrum that drives the flowering response.\u003c\/p\u003e\n\n\u003cp\u003eMost cheap panels give you one fixed spectrum and expect the plant to cope. This one gives you two. Flick to VEG and the 660nm and 730nm diodes go off, leaving a white-dominant spectrum that keeps young plants short, bushy and strong. Flick to BLOOM when they're ready and those diodes come back on to drive the flowering stage. It's one switch, and it's the difference between a plant that stretches and one that builds structure first.\u003c\/p\u003e\n\n\u003ch3\u003eCoverage \u0026amp; Placement\u003c\/h3\u003e\n\n\u003cp\u003eThese are recommendations based on the standard rule of 30–40W of actual power draw per square foot for flowering, and roughly half that for vegetative growth.
