Frisk Fra Boksen grows a variety of lettuces and herbs through an advanced hydroponic system every day of the year, even in the dead of winter when outside temperatures drop to well below zero. Gone are the days when tasteless iceberg lettuce made up nearly 90% of the market. Bambi, Butter-head, Romaine, Arugula, Kale, etc are all staples of the Frisk Fra Boksen hydroponic system.
