Hydroponics: Understanding the nutrient film technique (NFT) and deep-water culture (DWC) for water saving.

"Alright, we love the high-tech appeal and the huge 90% water saving—it sound’s brilliant for Jaipur! But let's be absolutely honest about the hidden price tag. First, the capital cost: this setup can be 8 to 10 times more expensive than a simple soil system; it’s a serious commitment! Second, the expertise: Forget guessing; you need serious chemistry knowledge, which leads to the dreaded OEM syndrome where you're forever reliant on the supplier for know-how. Third, every single one of your inputs (nutrients, media) is expensive. Fourth, your crop choice is narrow—mostly easy greens, tomato, cabbage, broccoli etc. And the final, biggest truth? While yields are huge, many find the taste is not as satisfying as soil-grown food after those first few novelty bites.

It’s high-efficiency, yes, but only for the highly committed, detail-oriented, and well-funded!"
