Val Techfarms Chennai
Fresh oyster mushrooms, grown indoors near Chennai.
Who we are
Val Techfarms Chennai grows fresh oyster mushrooms near Chennai. Chennai is too hot for oyster mushrooms to fruit well in the open, so ours grow indoors, in insulated rooms that are cooled, misted and ventilated. We make our own grow bags on the farm, pick by hand early in the morning, and supply trade buyers in Chennai.
Every morning, each room’s temperature, humidity and CO₂ are read with a handheld meter and logged.
How we grow
Bags made on the farm
We soak wood pellets, mix in spawn and seal each bag by hand, then hang the bags from the racks on rope loops, a method the farm worked out for itself.
Picked early, packed by hand
Harvest starts at about six in the morning. The mushrooms are graded, packed by hand into 200 g punnets, labelled and chilled.

What is mycelium? The part of a mushroom you do not see
Mycelium is the living body of a fungus, a mass of fine threads. A mushroom is the part it sends up to spread spores. Here is how that works, and how it happens in our grow bags.

How to store oyster mushrooms
Keep them cold and dry, in their punnet, and eat them by the date on the pack. Why a closed box or plastic bag makes them spoil faster, and the signs that they are going off.
