Most of the leafy vegetables, tomatoes, capsicum are most grown through hydroponics method or can be grouped under controlled environmental structures. I have my masters in agriculture, currently working in agri and some knowledge on MRL frameworks, recirculating system studies, and FSSAI guidelines.
At the end of it, I still couldn’t get a solid answer the question. is this actually cleaner than what comes from a field? There is a gap between a confident label and an uncertain answer. Because hydroponics came as option to exit the current system not purely as a technical improvement. Regenerative agriculture or Agroecology had made a slower, harder argument. if the soil itself could be restored, that damage caused by the conventional farming was not permanent.
Hydroponics skipped that entirely. if the soil health and metrics was the problem, it went without soil. What we didn’t remove the assumption that moving up means moving forward. Nobody stress-tested the new floor or current case. The person who ended up standing on it was the consumer, at a premium price.
Current Fix
Conventional farming gave us yield, tbh higher yields. Meanwhile I’ve written about POPs and the Dirty Dozen before. The chemical persistence problem isn’t theoretical. It’s in the soil, water, air and eventually, in us.
AE was supposed to be the correction. Building and bringing the soil back. Reduce external inputs or inputs itself. Restore biodiversity. Grow food in ways that don’t require the land to be worsen off after. The idea is sound. The business model isn’t established one yet.
Healthy soil, cleaner water, more biodiversity are real outcomes but they’re public goods. Nobody has to buy them. Carbon credit markets were supposed to monetize this value. Happening but that story slightly collapsed after 2023 when investigative reporting showed that a large portion of voluntary carbon credits were over counted or not real at all.
The real transition period costs roughly 3 to 5 years. The yields often drop before they recover and falls entirely on the farmer. And VC, which was interested for a brief window, has largely moved on. At World Agri-Tech 2026 in San Francisco last week, investors openly said they’ve cooled on regen ag. The exit math doesn’t work since it takes years.
So the gap stayed open. And something else stepped in or filling the gap right now.
Controlled Environments
Hydroponics and vertical farming arrived with a clean pitch. No soil means no soil-borne pathogens or pest. Controlled environment means no pesticide spray drift. Year-round production. Urban consumers are already primed to pay a premium for anything that sounds like conscious/clean food.
In an earlier post on the Organic Illusion, I wrote about how organic has become more of a feeling than a verified practice. Hydroponics slid neatly into the same emotional space. The clean, safe, more controlled without carrying the burden of formal certification (PGS). But three things are worth discussing.
First: controlled environment doesn’t mean no chemicals. Bacteria, Fungi and insect don’t disappear. Systemic fungicides and insecticides are still used in commercial hydroponic operations. In a closed recirculating system, these compounds behave differently than they do in a field. In a recirculating hydroponic tank, it loops/circulated back. The plant keeps absorbing it.
Studies from Wageningen University have shown that systemic compounds can accumulate in hydroponically grown produce at 2 to 4 times the concentration of soil-grown equivalents, under the same application rate. The label’s recommended pre-harvest interval the gap between last spray and harvest was calculated for field conditions. is it calculated for the tanks?
Second: the MRL framework wasn’t updated. The numbers that define what’s legally safe in food are set by FSSAI in India. They same standard applies to hydroponic produce as to field-grown produce. Same limit, fundamentally different production methods. Hydroponic farms sell into premium urban retail. The probability of a hydroponic farm’s produce being tested is low. Not zero, but low.
Third: this is the part I find genuinely strange: you cannot legally call hydroponic produce organic in India or the EU. Organic certification requires soil. NPOP, is built on a three-year land conversion process. No soil, no conversion, no certification. The EU took this explicitly in 2021. But in the USA, the USDA allows hydroponic organic certification. Same growing method. Different country, different legal identity for the same product.
There’s a quieter input problem that rarely makes it into the hydroponic conversation. Biofertilizers. Many commercial hydroponic operations use microbial inoculants such as mycorrhizal fungi, nitrogen-fixing bacteria, Trichoderma strains. This is to manage nutrient uptake and suppress harmful microbes in the liquid.
In practice, the quality and composition of commercially available biofertilizer products in India is poorly regulated. A 2022 review by ICAR flagged that a significant proportion of biofertilizer products on the market either didn’t contain the declared organisms or contained them at non-viable counts.
Which means a brand can’t say organic. So what do they say?
Most of the produce are labelled as chemical free, toxin free, 100% natural, farm to fork, clean food. None of these are permitted claims under FSSAI labelling regulations.
Who absorbs the uncertainty?
The smallholder can’t afford the capital costs of a controlled environment setup to compete and the premium price. The consumer pays the premium but has no way to verify the claim. India has no official data on how much hydroponic produce is grown, sold, exported or residue-tested domestically, because the data does not classify produce by commodity, not by growing method.
In the traceability post I wrote a few months ago, I made the point that India built food safety systems for Brussels and Boston, not for a village in India. GrapeNet, MangoNet, Peanut.Net all of these exist because foreign buyers demanded compliance. Hope the domestic market gets labels all the produce soon.
We moved from dirty conventional farming to clean-sounding controlled-environment farming, and again, the accountability infrastructure didn’t come with us.
This post isn’t about the critics. Many of them genuinely believe in what they’re building. But belief isn’t the same as verification. And in a system where the MRL framework hasn’t caught up, labelling rules aren’t enforced, organic certification doesn’t apply, and there’s no mandatory pre-market residue testing. Belief is all the consumer has to go on.
The honest answer is that nobody does, not in any verified, systematically tested sense. The system hasn’t built that accountability yet. And until it does, clean food is still more of a feeling than a fact.
We moved upstairs from a dirty floor. It’s worth asking whether we checked the new one before we sat down.
Cheers!
