Whitefly in the Greenhouse and on a City Farm: How to Identify, Stop, and Prevent an Outbreak
Spring brings not only the first greens and long-awaited warmth — it also wakes the whitefly. In greenhouses and city farms it never truly disappears, but as temperatures rise it reproduces so fast that a single unnoticed female can become a colony of hundreds of thousands within two or three months.

Irrigation Systems for Edible Flowers on a City Farm: Top Watering, Flood-and-Drain, and Capillary Mat
The word “hydroponics” covers dozens of different systems — from floating rafts to drip tape in substrate. But the goal is the same in all of them: deliver consistent nutrition to the plant and keep the root system healthy for as long as possible. Let’s get specific — how to irrigate edible flowers in pots […]
Multi-Cut Baby Leaf: Economics, Technique, and Microbiological Safety
The cut-and-come-again method is gaining ground in protected cultivation for a simple economic reason: one planting, multiple harvests. Seed, substrate, and pot costs are spread across three to five or more cuts instead of one. But the method has its own discipline — sanitation protocol, cutting technique, and root protection after each harvest. Get those […]
Lettuce Shelf Life After Harvest: Temperature, Ethylene, and Cooling Methods That Actually Work
Lettuce is a crop that spoils not in the field, but after it. Most growers lose 15–25 % of marketable value not through disease or pests, but through poor handling in the first hours after harvest. Temperature, storage neighbours, and the cooling method matter more than any agrochemical protection. Why Lettuce Spoils So Quickly Lettuce […]
Light and Temperature on a City Farm: How Two Key Factors Shape Your Yield
No light, no growth. That is not a metaphor — it is literal plant physiology. Among all the microclimate factors on a city farm, light stands apart. It does not just matter; it defines how active all the other parameters can be. Temperature, humidity, irrigation, CO₂ uptake — all of these adjust to the light […]
Fungus Gnats on a City Farm: Where They Come From and How to Get Rid of Them
Those tiny black flies hovering above your trays are not just an annoyance — they are fungus gnats (sciarids), and while you are waving the adults away, their larvae are already eating the roots of your microgreens. Here is where they come from and how to stop them at every development stage simultaneously. What Fungus […]
Mould on a City Farm: Why It Appears and How to Eliminate It for Good
You spot a fluffy white ball on a tray — straight into the bin. No deliberation. But do you know why it appeared in the first place, and what to do so it does not happen next time? Mould on microgreens is not just an inconvenience. It is a signal: somewhere in your process there […]
₴50,000 a Month from Microgreens on 10 m² — Myth or Reality? We Do the Maths
You have definitely seen it. Ads on Instagram, YouTube, Telegram. A smiling person in front of green shelves explaining how they transformed their life. “Started from zero,” “minimal investment,” “now earning ₴50,000 a month from 10 square metres.” And then — a button: “Buy the course.” We picked up a calculator and counted everything — […]
