Taming Bitterness: How Hydroponics Could Create Milder Veggies

Dr. Russell Sharp explores how breeders, genetic tools (including CRISPR) and environmental controls in hydroponics can reduce strong or bitter flavours in vegetables.

He highlights examples—low‑sulphur Brussels sprouts and onions, milder marrows/zucchini, soap‑free coriander, low‑oxalate spinach, less‑phenolic eggplant and sweeter lettuce—and points to hydroponic fertilizer strategies and business opportunities for growers and breeders.
