هیدروپونیک بدون شبکه: بدون نیاز به برق

Overview: This book was written to explain the Kratky method of hydroponics. The Kratky method refers to growing plants in a nutrient solution as you would in hydroponics however you do not use an air stone and the roots are mostly submerged at all times in the solution. This method is possible with many different plants and works very well for growth.
