Class 8 Vocational Education Textbook Work with Life Forms Chapter 1 Hydroponics Growing Plants without Soil question answer
Wick-based hydroponics uses a cotton wick from nutrient solution to plant roots. DWC suspends plant roots in nutrient-rich, aerated water using an air pump. NFT runs a thin film of nutrient solution along plant roots in channels. All three systems support soilless growth and use minimal water, with NFT being more efficient but complex. These setups help in faster plant growth and space-saving farming.
