It is made for grassland and dung-loving species that want warmth, a cased surface and a lot of fresh air. No humidifier, fan, tent or timer required.

Why growers pick the Grass Lover's XL

Grower's Select digital aquarium heater, digital probe thermometer and the vacuum-sealed manure substrate bags
Warmth from below

The bottom tote holds water and the Grower's Select digital heater keeps it in the low 80s. The grow tote floats on top, so the substrate stays warm even in a cold, dry room.

Kit heater, low-profile tote, and a hand misting a cased tote
Air without a fan

Shallow 6" totes give a wide surface and short air path. A window screen and an angled lid replace the fan and humidifier: you mist three times a day and they hold the moisture.

Complete XL kit contents: totes, heater, three 32 oz 5-grain jars, substrate bags, casing and screen clamps
Nothing to mix or cook

Grain is sterilized, substrate is pasteurized and vacuum sealed, and the casing is sterilized and ready out of the bag. Inoculate the jars and you are done prepping.

How the GordoTEK tote method works

The short version of the method. Watch Gordo's video and read his full write-up on the GordoTEK Easy Tek page before you start.

Gloved hands sprinkling colonized grain spawn from a 32 oz jar over manure-based substrate in a shallow tote 1Spawn to substrate

Once the three jars are fully colonized, shake them up, spread the substrate in the top tote and mix the grain in evenly. Pat the surface smooth and put the lid on.

Grower's Select digital aquarium heater and digital probe thermometer for the water bath 2Float it on warm water

Fill the bottom tote about halfway with warm water, add the heater and float the grow tote on top. Keep the water in the low 80s °F and leave the lid closed until it colonizes.

Gloved hand sprinkling a thin layer of peat and vermiculite casing over colonized substrate 3Add a thin casing

When the surface is fully white, sprinkle on a thin, even layer of casing, about 1/4". Spray it down heavily. You are now in fruiting conditions.

Hand misting a window screen clipped over a shallow tote, with the wet lid resting at an angle to leave corners open 4Screen, lid, mist

Clamp the screen over the tote. Mist the casing and both sides of the screen three times a day, then set the wet lid on at an angle so two corners stay open. Rotate it each time.

Tip from GordoTEK: if a gap opens between the substrate and the tote wall, pour a little water straight into it. After each harvest, pour about 1/2 cup of water slowly across the surface. The lid should always show some moisture on its underside; if it is dry, water more.

Prepared in-house, ready to use

No buckets, no pressure cooker

Every bag in this kit is made at our Illinois facility. The manure-based substrate is a blend of sun-aged, pasture-fed horse manure, finely chopped straw, coir, vermiculite and a pH buffer. It is hydrated, pasteurized and vacuum sealed in 3 lb bags. The casing is sphagnum peat moss and vermiculite, pH-adjusted and sterilized.

  • Substrate pasteurized, like our Willy's Blend
  • Casing sterilized, like our Master's Mix bags
  • Grain jars pressure-sterilized
Pasteurized vs. sterilized

The manure substrate is pasteurized at 160°F for 3–4 hours. That knocks back competitors while keeping the beneficial microbes manure-based substrate is known for.

The casing sits on the surface the whole fruiting cycle, so it is fully sterilized at 15 PSI before it ships.

What's in the kit

FAQ

Is this the GordoTEK kit?

Yes. This is the full-size kit we built with GordoTEK to match his Easy Tek: the recommended low-profile totes, the heater, the screen, 9 lbs of manure-based substrate, casing and grain. He reviews and approves our samples, and links to this kit from his write-up.

Do I need a humidifier, fan or grow tent?

No. The warm water bath, the screen and the angled lid do that work as long as you mist three times a day. In a very dry room a humidifier nearby can help, but most growers don't need one.

What temperature should the water bath be?

The low 80s °F. GordoTEK sets his heater to 82°F. Use the included probe thermometer to check the water and adjust the heater if it drifts.

How thick should the casing layer be?

Thin: about 1/4", sprinkled on evenly and sprayed down heavily. The 5 lb bag is more casing than one grow needs, so you will have some left for the next one.

How do I inoculate the grain jars?

Use 3–4cc of spores or 5–7cc of liquid culture per 32 oz jar. Shake liquid culture syringes well first. Spores and cultures are not included.

How long does the tub take to colonize?

In GordoTEK's grows the tub usually colonizes in 6–8 days in the warm water bath. Leave the lid closed until the surface is fully white, then case it.

Can this kit be used for Panaeolus cyanescens (formerly Copelandia cyanescens)?

Technically, yes: GordoTEK built this method around the warm, high-fresh-air, cased conditions that grassland and dung-loving species need. We sell it for lawful cultivation only, so check your local laws and regulations before growing any species.

What do I buy for the next grow?

The XL Refill Kit covers the substrate and casing. Add a 3-pack of 32 oz 5-grain jars for spawn. The totes, heater, thermometer and screen are reusable.

Note: This kit is sold for lawful cultivation only. It is not intended to grow Panaeolus cyanescens or Psilocybe natalensis (now ochraceocentrata) unless you are legally licensed by your local agricultural or research authorities. Always check your local laws and regulations before cultivating any species.
