Growing mushrooms at home doesn’t need to be difficult! They may seem daunting but with our super easy Windowsill Mushroom Growing Kits, you can kick start growing your very own mushrooms at any time of year, ready for some delicious crop to use in the kitchen. After the first crop you should expect to see at least two more, with this kit including a handy instruction guide on how to get the best crops possible. Each kit measures 17.5cm (length) x 27.5cm (width) x 8cm (depth). Be sure to place them on a windowsill with slight shade, away from the direct sunlight that can dry out or prevent the soil from staying moist. Select your favourite from a choice of 4 different kits: White, brown, Oyster Grey or Shii-take. Each kit contains a base tray, colonised substrate, a bag of cover compost and a plastic lid.

Growing Information

Growing Instructions:
This kit is designed for indoor growing. Choose a clean area away from direct heat sources and draughts. Avoid direct sunlight to prevent overheating. Mushrooms prefer indirect, filtered light.

Step 1. Prepare the compost
• Remove the white bag containing the top soil from the packaging and store it separately in a cool place, ideally around 15°C (59°F).
• Place the transparent lid on the growing tray and position the kit at 20-25°C (68-77°F) for around 4 days.
• During this time the compost will become covered with fuzzy, white fungal threads called mycelium.
Except for spraying, leave the lid on the growing container throughout the entire growing process.

Step 2. Add the top soil
• Once the compost is fully overgrown with white mycelium, open the white bag of top soil. Spread it evenly and very loosely over the compost until it is completely covered.
• Do not press down on the top soil.
• Now pull 4 or 5 strands of straw from the compost through the soil in 6 places.
• Keep the lid closed and store the kit at 20-25°C (68-77°F) for 5 to 8 days.
• Lightly mist the top soil once a day for 5 days.
• During this stage, the mycelium will grow up through the soil to the surface.

Step 3. Encourage mushroom formation
• When white fluff is visible on the surface, move the kit to a cooler spot at 16-17°C (61-63°F).
• Spray lightly every 2 to 3 days.
• Small, dense clusters called pin heads will form, first around the edges, then across the centre.

Step 4. Harvest
• Most pin heads will grow into full sized mushrooms.
• To harvest, hold the mushroom between two fingertips and twist carefully. Do not pull.
Please note: mushrooms do not grow at the same rate, so leave any that are not yet ready and continue spraying lightly until all are harvested.

Step 5. Further harvests
• Once all mushrooms have been harvested, moisten the top soil with water until it feels wet but not soggy.
• Allow the kit to rest for 5 to 6 days at 20-25°C (68-77°F), then repeat from step 3 for another flush.

Live Plants

Suttons strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3.

Non Standard Deliveries

Unfortunately like many companies in our industry we are currently only able to supply orders to UK based customers, excluding those in Northern Ireland. We are committed to finding a way that we can resume or normal services again as soon as possible. Please accept our apologies for any inconvience caused.

Prices include VAT where applicable.

We reserve the right to contact you and advise an additional charge where necessary and are happy to quote for carriage of specific products to more remote areas. Some items may not be available to all areas.

We reserve the right to revise any carriage charges in the event of carrier price increase or other unforeseen circumstances. We will always advise of the carriage charge before payment is taken.

Large Non-standard items may incur a higher, lorry delivery charge. Charges will be calculated at checkout, but an example of the lorry charges are listed below.

Red - £9.99.
Purple - £2.99.

What our customers say

"Very impressed with the quality of leek and broad bean seeds you sent. Excellent germination and look forward to a bumper crop. Will certainly be back."

E. Smyth

“I bought all my seeds, potatoes, etc. from your catalogue last year for my new ‘larger’ vegetable garden. I have to say I have never had such success in the garden. The germination was excellent; the quality of plant stock and produce is superb."

Sadie

“I am compelled to write to you and your staff for the exemplary service provided by your company, in an age where the word and term ‘service’ has lost its meaning.”
