Mushroom Grow Kit (Supplemented Grain, 2 litres)

(5 customer reviews)

£37.50 inc. VAT

A supplemented version of our popular PF-Tek Mushroom Grow Tubs – Pre-steralised and ready for inoculation with any one of our liquid cultures or spore syringes.

A massive 2 litres of highly nutritious substrate with a unique blend of organic rye grain, wild bird seed, coconut coir, coffee, seaweed extract and gypsum.

PH Balanced, steralised and ready for inoculation. Faster colonisation times of up to 25% compared to our BRF based MycoTUB range and geared for more more experienced cultivators who want the best for their shrooms.

* Due to the high nutrition, familiarity with sterile technique is essential. Not suitable for most wood-loving species. *

Simply inject 0.5-1 ml of a suitable liquid culture or spore syringe solution into each of the inoculation ports, store at room temperature and watch for growth. Full colonisation in around 25 days. The tub is re-usable so you can always experiment with your own mixes after you’ve harvested all your mushrooms from this kit.

  1. lilly

    I bought 4 kits, 1 of which got contaminated πŸ™

  2. Tommy & Juliette

    Bought a kit for the wife about 2 weeks ago as she's been getting into her gardening and healthy eating of late. Injected the liquid culture about a week ago and can already see mushroom roots growing! At this rate, I think another 3 weeks and it'll be completely white. Then can move onto the next stage which is growing some mushrooms!! Very excited as we've never grown mushrooms before. Will be back for more if these go well!!

  3. Ousman

  5. Sawyer

    Kept in freezer for 1 month before using, defrosted and allowed to get up to room temperature before inoculating. Strong signs of mycelial growth which looks beautiful against the black substrate. No signs of contamination, looking forward to harvesting. Came with free gift and a couple of product 'samples'. Thanks πŸ™‚
