If you are weighing mushroom substrate bag vs Myco Labs options, you are really choosing between 100PCS Mushroom Planting Kit and Myco Labs All-in-One Mushroom Grow Bag for Manure. One gives you a large supply of empty bags to fill with your own grain and bulk mix, while the other gives you a single pre-filled 6LB kit with a Mini Liquid Culture Jar. Your choice shapes how much prep you handle yourself and how many grows you can launch at once.
As of September 2026, the real decision is scale versus simplicity. Do you want full control over recipes and the ability to run dozens of bags, or do you want a guided manure loving grow with less measuring and mixing. If you are browsing Substrate, CVG and Bulk Amendments for your next run, this head to head will help you match the format to your skill level, space, and goals.

Pros
- Extra thick 6 mil construction for superior durability compared to standard spawn bags
- High temperature resistant material works reliably for sterilization and spawning
- Breathable filter design promotes healthy mycelium colonization
- Generous size and self-standing gusset makes filling and handling easier

The zwxt 100PCS Mushroom Planting Kit is a bulk set of 8x5x20 inch spawn bags designed for growers who inoculate their own substrate with spores or liquid culture. It is ideal for beginners scaling up and professional growers running continuous indoor or outdoor cycles.
The 0.2 micron filter patch delivers reliable gas exchange to support vigorous colonization while helping keep contaminants out. In practical use, the roomy interior easily holds grain, sawdust or supplemented substrate up to 4.2 pounds for strong flushes.
Built from 6 mil polypropylene, these bags feel noticeably thicker and more tear resistant than standard spawn bags. The gusseted sides expand for easy filling and help the bag stand upright and stay stable on a tabletop during inoculation.
As expected with professional style spawn bags, there is no zip seal or pre sterilized substrate, so you will need a pressure cooker and your own media. The 100 count format is also bulky to store if you only grow occasionally.
Overall, this is a durable, high airflow and autoclavable solution for serious mushroom cultivation. If you want a dependable bulk supply that holds up to sterilization and handling, this kit is a smart pick.
Pack Size: 100 mushroom grow bags, Size 8 x 5 x 20 inches with rectangular gusseted shape.
Material: 6 mil thick polypropylene, tear resistant and high temperature resistant for sterilization.
Filter: 0.2 micron porosity breathable window for balanced gas exchange.
Capacity: Holds up to 4.2 pounds of substrate, self standing design for tabletop use.
Use: Compatible with spores or liquid culture, suitable for indoor and outdoor mushroom growing.
Pros
- Higher success potential by confirming healthy mycelium in the jar before inoculation
- Faster colonization compared to direct spore injection into substrate
- Large 6.1 pound capacity supports stronger yields in one bag
- Beginner friendly setup with no pressure cooker, mixing or extra containers needed
Cons
- Spores or culture must be sourced separately as they are not included
- Large bag size requires patience and stable, clean conditions for full colonization
- Injection only workflow may feel limiting for advanced growers who prefer agar or grain transfers
The Myco Labs AIO6 is a 6 pound all in one mushroom grow bag designed for manure loving mushrooms, bundled with a 30ml spore germination jar. It is built for beginners who want to skip sterilization and mixing, as well as pros who want a convenient high capacity setup.
The standout feature is the mini liquid culture jar that lets you germinate spores into visible mycelium before touching the bag. In practice, this pre check helps catch contamination early and inoculating with active liquid culture can colonize noticeably faster than direct spore injection.
Each bag combines pre sterilized grain and substrate selected for fast growth, with simple injection ports for clean inoculation. The kit includes the bag, jar and sterile inoculation tools, so the workflow stays contained, tidy and easy to manage at home.
The 6 pound size is great for yield potential, but it demands patience and stable temperatures for full colonization. You will still need to supply your own spores and practice good sterile technique, since contamination is still possible if inoculation is rushed.
For growers who want simplicity without sacrificing harvest size, this is a smart and confidence building system. The germination jar adds real value by improving success rates and speed, making it one of the more beginner friendly all in one options available.
Brand: Myco Labs, Model: AIO6, Part Number: AIO6, Item Form: Bag for mushroom growth.
Capacity: 6.1 pound all in one bag with pre sterilized grain and substrate, Application Method: Injection.
Included Components: All in One Bag, 30ml Liquid Culture Jar, Sterile Inoculation Kit, Target Species: Mushrooms.
Start by germinating your spores in the 30ml liquid culture jar until you see healthy mycelium growth.
Once confirmed, inject the liquid culture into the 6LB grow bag through the sterile injection port.
Incubate in a warm, clean space and allow full colonization before moving to fruiting conditions.
How They Compare
What You Actually Get
The 100PCS Mushroom Planting Kit is a bulk supply of empty 6 mil polypropylene spawn bags, with 100 pieces in the pack for repeated runs. The Myco Labs All-in-One Mushroom Grow Bag for Manure is a single XL 6LB grow bag that arrives pre-filled with pre-sterilized grain and substrate material plus a Mini Liquid Culture Jar for germinating spores first. We assessed both options side by side as complete workflows, not just as bags.
For you, this means the 100PCS Mushroom Planting Kit requires you to source grain, bulk ingredients, and spores or liquid culture separately. The Myco Labs All-in-One Mushroom Grow Bag for Manure bundles the grain, substrate, and germination jar together, which reduces shopping and measuring. If you enjoy building custom mixes, the bulk pack gives freedom, while the all-in-one removes several prep steps.
Size, Strength and Air Exchange
The 100PCS Mushroom Planting Kit uses a large 8 x 5 x 20 inch bag with side gussets that help it stand and hold shape during filling and colonization. It is made from 6MIL polypropylene that is described as thicker than most bags, with a rated capacity up to 4.2lb per bag and a 0.2 micron filter window for gas exchange. The Myco Labs All-in-One Mushroom Grow Bag for Manure is built around a single XL 6LB capacity, which is larger per bag and aimed at maximum yields from one run. Check our bulk substrate guide if you are unsure how bag size affects fill depth and colonization time.
In practice, the 100PCS Mushroom Planting Kit gives you more flexibility to run small 2lb fills or fuller loads across many bags, while the Myco Labs All-in-One Mushroom Grow Bag for Manure commits you to one large manure based block. The 0.2 micron ventilation window on the 100PCS Mushroom Planting Kit is suited to growers who want steady fresh air exchange without fanning constantly. The Myco Labs bag focuses on a simplified sealed environment where you inoculate with liquid culture mycelium after germination in the jar.
Workflow, Sterility and Skill Level
The 100PCS Mushroom Planting Kit is designed to withstand high temperatures so you can process your own filled bags in your sterilization setup, and the material is rated as durable and tear resistant for handling. That is a plus if you already own sterilization equipment and trust your sterile procedure, but it is a con if you do not, because any contamination comes from your kitchen, tools, or mix. The Myco Labs All-in-One Mushroom Grow Bag for Manure arrives with pre-sterilized grain and substrate, so you skip home sterilization and move straight to spore germination and inoculation.
The standout difference is the Mini Liquid Culture Jar included with the Myco Labs All-in-One Mushroom Grow Bag for Manure, which lets you watch spores become mycelium before you risk the main bag. The 100PCS Mushroom Planting Kit has no jar, no grain, and no substrate included, so you must manage every sterile transfer yourself across dozens of potential bags. If you are still learning sterile workflow basics, the Myco Labs approach lowers early failure risk, while the bulk bags reward experienced growers with more control.
Scale, Consistency and Community Feedback
The 100PCS Mushroom Planting Kit is rated 4.5 out of 5 from 178 reviews, which reflects satisfaction with thickness, size, and value for high volume work. The Myco Labs All-in-One Mushroom Grow Bag for Manure is rated 4.2 out of 5 from 212 reviews, showing solid results for a convenient kit with more varied expectations around single bag yields. With 100 pieces, the 100PCS Mushroom Planting Kit lets you standardize your process and repeat the same recipe many times to dial in results.
For consistency, the Myco Labs All-in-One Mushroom Grow Bag for Manure offers a carefully selected grain and substrate blend that is the same every time, which helps beginners avoid recipe errors. The tradeoff is that the 100PCS Mushroom Planting Kit puts consistency entirely on you, from moisture content to fill weight to seal quality. If you want to run side by side comparisons of strains or bulk ratios, the bulk pack is far more practical than buying many single 6LB kits.
Which One Should You Get
Choose 100PCS Mushroom Planting Kit if you want to run multiple monotubs, trays, or bags per month and you already mix your own grain and bulk substrates. You get 100 large gusseted bags with 0.2 micron filtration, 6 mil walls, and up to 4.2lb capacity each, which is ideal for scaling up, sharing with a grow group, or refining a house recipe. Explore amendment options for coir, vermiculite, and gypsum to pair with these empty bags, and plan storage space because 100 bags take real shelf room.
Choose Myco Labs All-in-One Mushroom Grow Bag for Manure if you grow manure loving varieties and want the shortest path from spores to a colonized block. You get an XL 6LB pre-sterilized grain and substrate bag plus a Mini Liquid Culture Jar that helps you confirm viable mycelium before inoculation and shave weeks off the schedule. This is the better fit for your first or second grow, for small apartments, or for anyone who does not own sterilization gear and prefers a contained, guided process.
Who Should Skip Both
Both of these options are not ideal for growers who focus only on wood loving species on logs or sawdust blocks, or for anyone who wants a fully automated fruiting chamber with humidity control included. If you need verified organic certification paperwork, exact ingredient percentages, or a reusable tub setup rather than disposable bags, you should look at other formats in our Substrate, CVG and Bulk Amendments section before you buy.
Frequently Asked Questions
Is Myco Labs All-in-One Mushroom Grow Bag for Manure good for beginners?
Yes, it is often a good fit for beginners who want manure loving mushrooms without mixing and sterilizing grain at home. The included Mini Liquid Culture Jar helps you confirm growth before inoculating the 6LB bag. You still need clean inoculation habits and proper fruiting conditions for best results.
Can you reuse the 100PCS Mushroom Planting Kit bags?
These are designed as single use spawn and substrate bags, and most growers dispose of them after harvest to reduce contamination risk. The 6 mil polypropylene walls are durable and tear resistant during filling, handling, and high temperature processing. With 100 pieces included, you have plenty of fresh bags for future runs without needing to wash and reuse.
Which is better for bulk manure grows, empty bags or Myco Labs?
For large bulk manure grows with custom ratios, the 100PCS Mushroom Planting Kit is more practical because you can fill many 8 x 5 x 20 inch bags up to 4.2lb each. For a simple single batch manure grow, the Myco Labs All-in-One Mushroom Grow Bag for Manure is easier because the 6LB grain and substrate blend arrives pre-sterilized. Your skill level and batch size should drive the choice more than brand alone.
