Conventional regen farm designs are usually extremely expensive, as they rely on heavy firepower to eliminate the tremendous number of bloons that flow out of the farm. This video shows a regen farm design that uses dynamic feedback to regulate itself so that bloons flow out at a more manageable pace. This approach drastically reduces the cost of the regen farm so that they can be routinely created in Round 31 (the earliest possible round for regen farming) on just about any track. Regen farming early in the game helps secure additional funds that can be used to ensure eventual victory on the track. You'll only need to make a few thousand dollars on the regen farm to make a big difference, especially if you invest wisely. Or you can just come back after a couple hours and buy a Temple of the Monkey God.


A regen farm operates based on the fact that certain bloons contain 2 regenerating bloons inside. When the parent bloon is popped, the 2 children bloons may regenerate to produce 2 new parent bloons. The process is repeated to create a large number of bloons. Some of these bloons are sacrificed for points, are the rest are "recycled" in a loop on the track so that more bloons can be made in a self-sustaining fashion.


In this regulated regen farm design, the downdraft from a heli pilot (0/3) is used to recycle bloons on the track. If there are too many bloons in the farm, the heli pilot can't shoot them fast enough, so it is soon overrun by the bloons. Since the heli pilot automatically shoots at the leading bloon in its range, it pivots to shoot away from the farm, which causes newly approaching bloons to be blown back without being shot at. Since these recycled bloons are not popped, they do not replicate, so the number of bloons in the farm decreases until the heli pilot is no longer overrun. When the heli pilot is no longer overrun, it turns back to shoot at the approaching bloons. This causes them to replicate so that the number of bloons increases until the heli pilot is again overrun. The farming process is loosely regulated in this fashion to maintain a fairly stable regen farm that typically generates about $1000 to $2000 per minute in fast forward mode.


When starting the regen farm, the heli pilot may be too powerful on Round 31, which has only 2 zebra bloons as "seeds." Its guns will often overpower the seed bloons before the farm can get started, so there are a number of steps to jumpstart the farming process. The first step involves using a dart monkey (0/0) to shoot at the initial zebra bloon(s) so that they replicate before reaching the heli pilot. This dart monkey should be sold after the initial pass of the zebra bloon(s). The glue gunner(s) (1/0) slow the bloons down to give them more time to regenerate. The ice tower (1/0) creates a shield of frozen bloons that the heli pilot cannot shoot through, and the ice tower may also be used to further slow down the recycled bloons if needed by upgrading to 1/1 or 1/2.

The bloons that flow out of the farm can be destroyed by any reasonable means, but I tend to use spike factories, as they can be very compact and are easily placed near the end of the path, if necessary. As you earn more money, the spike factories are readily upgraded to mitigate the risk of being overrun by a surge in bloons. Dartling guns (3/0) are also useful for popping bloons, but they are less compact than spike factories, and they can be difficult to control unless you use the level III specialty upgrade on the Dartling Ammo Dump, which allows you to lock the dartling gun aim.

This video demonstrates a regen farm in Round 31 of Bloontonium Lab played on hard mode, which is often viewed as the most difficult track in the game. I start with a centrally located monkey engineer and upgrade the sentries after Round 2 (to 1/0) and around Round 16 (to 2/0). All other funds are invested in banana farms and associated upgrades. I use the level IV specialty upgrade for the Engineer's Workshop to keep things simple. If you don't have at least the level III upgrade, which allows you to pop lead bloons, you should add corrosive glue gunners (2/0) before Round 28.
