TPS One™ 55 Gallon Barrel

TPS One™ 55 Gallon Barrel by TPS Plant Foods

The same seed-to-harvest formula as TPS-One, packaged for operations that measure their reservoirs in hundreds of gallons.

Why it works:

  • Gentle liquid formula — mix it into your normal watering, no separate feeding routine

Why buy direct

More than a bottle on a shelf.

  • Talk to real plant people. Questions about your plants? Our team makes the formula and answers directly — you're not on your own.
  • Made in-house, in the USA. Every bottle mixed and filled by us, not a third party.
  • Backed by our Healthy Plants Guarantee. Feed it for 30 days — if you don't see healthier growth, we'll make it right.
