What to look for on the hydro shop shelf & surprising microgreens findings
Dr. Russell Sharp revisits fertilizer and biostimulant preservation—what shrinking, bloating, and floaty bits in bottles actually mean—and shares practical signs to watch for.
He then summarizes microgreen experiments: pea shoots performed well without fertiliser or growing media, wheatgrass responded strongly to low-dose feeding, and ongoing trials include spring onions and a seed coating to deter slugs.

The Dirty (half) Dozen: Harmful Preservatives Hiding in Your Fertilizer
Dr. Russell Sharp of Hydroponics Daily exposes common and dangerous preservatives found in fertilizers and biostimulants, including formaldehyde, quaternary ammonium compounds (BAC50), copper sulfate, bronopol and silver.
He explains why growers should check product labels and safety data sheets, prefer food‑grade preservatives, and be aware of impacts on human health, plant uptake and beneficial microbes.
Practical tips include researching ingredient CAS/EC numbers, using reputable formulations, and choosing safer preservation strategies to protect crops and consumers.

Don’t Pour Food Waste on Your Plants!: The Hidden Danger
Dr. Russell Sharp explains why pouring liquidised food waste or adding uncomposted plant material to soil or lawns can harm plant growth. Microbes decomposing fresh organic matter use up available nitrogen, causing nutrient deficiency and chlorosis in plants, and the practice can also attract pests like rodents and rabbits.
Advice: always compost organic waste first or boost nitrogen levels if you must add fresh material, and avoid leaving food scraps on borders to prevent pest problems.
