What we supply

FAQ

How long does an order take?

Everything is made to order, so allow a few working days for us to prepare it. For large orders we'll confirm a dispatch date when you order.

How is my order delivered?

Smaller orders go by Royal Mail Tracked 48 in boxes of up to 25kg. Bigger orders go on a pallet, and every pallet comes with a tail lift, so you don't need a forklift. Royal Mail and pallet delivery are free anywhere in the UK. Can't take a pallet delivery? We can bring your order in our own van, anywhere in the country. A delivery charge may apply, so ask us for a price.

Do you deliver to Europe?

Yes. Smaller orders go by UPS and larger orders on a pallet. Get in touch for a quote, including shipping and any import taxes.

Is there a minimum order?

Wholesale prices start at 25 bags. If you need fewer, our 12 packs and the multi-buy discounts in the main shop are the next best price.

Can I mix products to reach a price tier?

Yes. For example, 50 rye and 50 millet bags at the 100 bag price. The website can't build mixed orders, so fill in the form below and we'll send you a pro forma invoice.

How can I pay?

By card, Klarna or bank transfer, or cash if you collect. For bank transfer we'll send a pro forma invoice and dispatch once payment has cleared.

Can I collect my order?

Yes, from our unit in Castleford, WF10 1NZ. Let us know when you order and we'll tell you when it's ready.

What if a bag is contaminated?

All our sterile products come with the Sporogenesis guarantee. We recommend keeping sterile bags sealed for a week after delivery before you inoculate, to confirm they're sterile. If any show contamination, let us know and we'll replace them.

How long do the products last?

Sterile grain and Inject & Forget bags are guaranteed for at least 6 weeks from delivery. CVG is guaranteed for at least 12 weeks.

Do you do white label?

Yes. We can supply bags with your own printed labels, or without labels so you can add your own. Get in touch for details.
