Easy steps for growing arugula greens indoors through winter:

• Beans most productively under full spectrum (6400K) grow lights. We recommend Sunblaster T5 lighting. Grow lights should be maintained 6 - 12” above plant tops and should be on 16 - 18 hours per day.
• During the months where daylight-hours are low beans must be grown under full-spectrum lights.
• Indoor beans grow very well in 15 cm (6") containers with drainage or longer trough-style containers with drainage.  
• Use a composty indoor soil. We use an organic potting mix blended with Sea Soil compost at a 60 / 40 ratio. By building in high-quality compost you can avoid any need for additional fertilizing.
• Beans take 2 - 5 days to germinate. The ideal temperature for germination is 21º C; bottom heat will speed up germination and encourage faster seedling development. In general, beans thrive where air temperatures are warm.
• Wet your soil medium before sowing then poke seeds into soil to a depth of about 1.5 cm. Sow approximately 6 seeds in a 15 cm (6") pot.  
• Check on seeds every few days to notice when they are starting to germinate. Maintain soil moisture without allowing the mix to be soggy.
• Beans do not require special care or attention to be fertilized indoors. 
• Beans will grow indoors under lights for approximately six to ten weeks before a new crop needs to take over. Sow new trays every 4 weeks to keep a constant supply.

Additional Tips:

• Great air circulation around your indoor garden makes everything better! If you are growing lots of plants indoors consider adding a small fan to your set-up.
• If using humidity domes over your trays: be sure to leave these off for at least one hour per day to allow for air circulation.
• Pests rarely occur on indoor greens but it is a good idea to clean pots/trays with warm soapy water (or 10% bleach solution) between crops and generally keep your growing area tidy. Beans do attract spider mites, so always start with clean pots. 
• Crops that are grown to larger than baby green size will likely require fertilizing for best productivity; we recommend Evolve Organic All-Purpose Fertilizer for our indoor gardens.

Harvesting Tips:

• The more you harvest the more you will get new beans. 
• The beauty of growing your own baby greens is that you can harvest just what you need when you need it!
