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.
