A Richmond-area online seller of herbs is building a greenhouse in eastern Henrico County.

The Growers Exchange, which currently has operations on a 600-acre farm in Charles City County, has purchased land and soon will start construction on four acres at Tech Park Place in Varina, according to Commonwealth Commercial Real Estate, which helped broker the deal.

The Henrico-based real estate firm said access to transportation, workforce and Internet providers all played a role in the company’s decision on a location.
