The estimated building price for a 20 x 74 feet Walipini in La Paz, Peru is between $250 – $300. Taking advantage of inexpensive materials like PVC pipes and ultraviolet protective plastic sheeting enhance the savings. A detailed do-it-yourself building manual are available here and includes essential instructions for ventilation, drainage and waterproofing.. $300 underground greenhouse grows produce year-round, in severe climates even With staggering food prices and shortages looming, there’s no better time to grow your personal produce. Sadly, most greenhouses are costly to build and impractical to warmth during cold, wintery conditions.
