Agree the seedlings don’t need that intensity atm, 30” is great when vegging, raise to 52” if u don’t have t5 for the seed phase of the grow and lower to 24-36” based on genetics/ strain.
Sativa: high light intensity dependent
Closer light height levels/ max setting more blue / max red/ benefits with added white lights, side lighting
Indica: lower light intensity: more red
Higher light height levels : cooler temps
Side lighting isn’t as important flatter plant geography
Hybrid: dominant dependence use the
sativa vs indica profiles.
Led also makes heat just not as much as traditional hid.
Ensure great inflow and outflow of air to avoid dead air lights on and burning.
