ROB RUN Grow Room Guide
Setup • Harvesting • Upgrades • Profit Planning

The Grow Room turns collected bushes into repeat harvests. This guide explains the equipment you need, how the growing cycle works, and how to judge whether the investment makes sense before your server wipes.

1. What You Need

You need a suitable personal base, the production building, at least one working table, and bushes to place on it.

Item	Research	Purchase	Purpose
Grow Room	$150,000	$100,000	Houses the growing operation
Grow Table	$30,000	$40,000	Holds the bushes
First working setup	$180,000	$140,000	$320,000 combined

These are documented reference prices. Land, bushes, defenses, transport, and additional upgrades are not included.

Important: the table does not supply its own plants. You must obtain Growing Bush cargo separately.

2. Capacity

Community references list:

• 6 Grow Table positions inside one Grow Room.
• 6 bushes per Grow Table.
• 36 bushes when all six tables are filled.

Research is paid to unlock the item. Additional copies of an already-unlocked table require their purchase price rather than repeating the research payment.

3. Planting and Harvesting

• Obtain a Growing Bush and transport it to your base.
• Place it in an available Grow Table position.
• Check the growth indicator. A clock represents an active growing cycle.
• When it becomes ready, use the harvest interaction.
• Collect the Harvest Bags or Packages.
• Sell the harvest to the Fence.

The documented loop returns the harvested bush to a growing state of the same rarity. It does not require a replacement bush after each ordinary harvest.

4. Harvest Values

The following are listed base sale values before applicable bonuses:

Rarity	Value per bag	Reported bags per bush	Gross value per harvest
Uncommon	$4,000	2–4	$8,000–$16,000
Epic	$6,000	2–4	$12,000–$24,000
Legendary	$8,000	2–4	$16,000–$32,000

Example: six Uncommon bushes producing 2–4 bags each would generate $48,000–$96,000 gross at the listed base price.

This is a calculated range, not guaranteed profit. It assumes you harvest all six bushes and successfully sell everything.

5. Upgrades

Upgrade	Listed growth improvement	Vendor tier
Fan	12%	I
Water Pump	14%	II
UV Lamp	24%	III

Do not add these percentages together and assume that gives the exact reduction in total growing time. The game's calculation and the installed setup determine the result.

Investment advice: compare another filled table with a speed upgrade. More table space helps only when you can obtain bushes to fill it.

6. How Long Does Growth Take?

A complete, consistently verified timer for every bush rarity and upgrade combination is not established here.

Some databases show a tick period. A tick is an internal processing interval and must not be mistaken for the full time between harvests.

Measure your setup:

• Record when a freshly harvested bush starts its next cycle.
• Record when it becomes harvestable again.
• Note its rarity and installed upgrades.
• Repeat before estimating hourly income.

7. Calculate Your Break-Even Point

Startup investment ÷ net return per completed harvest = harvests needed to recover the investment.

Include the value of your bushes. A bush you found still has an alternative sale value.

For example, a $320,000 setup plus six bushes valued at $20,000 each represents $440,000 committed, before other costs.

At the earlier $48,000–$96,000 gross range, that is approximately 5–10 complete table harvests to match the committed amount, before losses or other expenses.

Practical rule: build early enough to benefit from repeat harvests. Near a wipe, immediate sale of a bush may be more useful than starting a new operation.
