I-QP ikhula amalambu ane-dimming knob, evumela abasebenzisi ukuthi bashintshe ubukhulu bokukhanya (i-PPFD) ngokuya ngesigaba sokukhula kwesitshalo (njengokuhluma, ukukhula kwemifino, noma izimbali). Ukuphakama okulengiswe nakho kungashintshwa ngezigaba ezahlukahlukene ukufezekisa ukumboza okulula nokuqina okukhanyayo okulula ukufanisa izidingo ngakunye kwesigaba ngasinye.
Ukukhula kwesitshalo kudinga amazinga ahlukile we-PPFD. Okwe-cannabis, amabanga yilezi: Isiteji sesithombo (100-300 μmol / m² / s), isigaba semifino (300-600 μmol / m² / 600-92; / s). Ungabhekisa ekusatshalalisweni kwe-PPFD ku-datasheet bese ulungisa ukuphakama kokukhanya kwetende.
