Description
Description
Run two strains in one tub. The Monotub Divider splits a Grower's Select Large 66Q or Medium 44Q monotub into two side-by-side grows, each in its own liner with its own label. It pressure-fits into place: no drilling, no glue, and no changes to your tub.
The kit includes the divider, two small pre-cut liners and two Monotub Tracker labels, so you can set up two separate grows the day it arrives.
Split a Grower's Select 44Q or 66Q into two side-by-side grows. It pressure-fits in, with no drilling and no glue.

Why growers split a tub
Both strains share the same tub, air, light and temperature, so the only real difference between the two sides is the genetics.
Every half gets its own liner, so the substrates never mix. If one side has a problem, lift that liner out and leave the other side alone.
The 3D-printed end posts are shaped to the exact wall slope of Grower's Select tubs and press against the walls. Anti-slip silicone pads keep it from sliding.
Set it up in 4 steps
It takes a couple of minutes. Watch the full setup in the video below, or see the quick-start guide in the photo gallery.
1Assemble & center
Peel the clear backing off the silicone pads and slide the panel into both posts. Set it in, thicker ends up, centered on the small circle in the tub floor.
2Press both sides in
Push both posts firmly against the side walls until it's snug. Fit check: the empty tub should turn upside down without the divider falling out.
3Install liners
Drop a small liner into each half. Use a piece of tape to secure each liner to the divider so it stays in place on its side.
4Spawn & label
Spawn each side, then stick a Monotub Tracker label in front of each half with the strain and spawn date.
Watch the full setup
Clean it by hand between grows. Wash the divider with soap and water and wipe it with 70% isopropyl alcohol. Don't boil it, pressure cook it or put it in the dishwasher. High heat can warp the 3D-printed end posts.
Half a tub's load on each side
Two strains, one tub
Each half is its own small grow. Plan on about half the tub's normal load per side, then colonize, fruit and harvest as normal.
- Large 66Q: one spawn bag or two 32 oz jars into up to 5 lbs of substrate per side
- Medium 44Q: about one 32 oz jar or half a spawn bag into roughly 3.5–4 lbs per side
- Write the strain and spawn date on each label
Both sides share one tub's air, humidity and temperature.
Two strains of the same species are the easiest pairing, like the two shown here. If you mix species, choose ones with similar fruiting needs.

FAQ
Which monotubs does the divider fit?
It fits the Grower's Select Large 66Q and Medium 44Q monotubs. The end posts are shaped to the wall slope and width of those tubs. Other brands use different tapers and widths, so we can't promise a secure fit in them.
Do I need to drill or glue anything?
No. The divider pressure-fits between the side walls and the anti-slip silicone pads hold it in place. Nothing is screwed, glued or cut into the tub, and it comes right back out when you're done.
How do I know it's installed tight enough?
Do the fit check: with the tub empty, turn it upside down. The divider should stay in place. If it slips, make sure the backing is peeled off all the silicone pads, the thicker end of each post is facing up, and the divider is centered on the indented circle in the tub floor.
Will the two strains mix?
No. Each side gets its own liner, and the panel sits between them, so the two substrates and their mycelium stay apart. Keep in mind that the divider separates the substrate, not the air. Both sides share the tub's air and humidity.
What if one side gets contaminated?
Because each half is in its own liner, you can fold the liner up over the contaminated cake and lift it out without disturbing the other side. Do it as soon as you spot the problem. The divider doesn't stop airborne spores, so watch the healthy side closely for the rest of the run.
How much spawn and substrate goes on each side?
Plan on about half the tub's normal load per side. In a Large 66Q, that's one spawn bag or two 32 oz jars into up to 5 lbs of bulk substrate per side. In a Medium 44Q, it's about one 32 oz jar or half a spawn bag into roughly 3.5–4 lbs per side.
Can I grow two different species at the same time?
Yes, as long as they like similar conditions. Both sides share the same temperature, humidity and fresh air exchange, so pair species with similar fruiting needs. Two strains of the same species are the simplest setup.
Is the divider reusable, and how do I clean it?
Yes. After each grow, wash it by hand with soap and water and wipe it with 70% isopropyl alcohol. Don't boil it, pressure cook it or put it in the dishwasher. High heat can warp the 3D-printed end posts.
Does it come with a marker for the labels?
No. The kit includes the two labels only. Any fine-tip permanent marker works, and the ink wipes off with isopropyl alcohol so you can reuse the labels. The Monotub Tracker Label Kit includes a 0.4 mm marker and alcohol pads.
