what you built
For growers who spent years on their soil and won’t risk it: how Bloom is used in living soil, teas and organic programs, and a very clear statement of what Bloom is not.

Who this is for
The hardest customers in the shop
Living-soil growers have spent years building something biological, and they’re not going to pour an unknown bottle into it on anyone’s say-so.
Six growers in Bloom’s record run teas, living soil or organic programs. They use Bloom the way they’d use any amendment: over the top, carefully, watching what happens. One ran a side-by-side on the same organic base.

What’s actually different
Three things worth knowing
It layers, it doesn’t replace
Bloom products are additives over an existing feed. For a living-soil grower, that’s the only acceptable shape.
Growers use it their own way
One dips clones in a 12-gallon Roots batch. One adds it to compost tea. One split two plants on the same organic base, one with Bloom on top. The record shows adaptation, not a schedule.
We don’t overclaim
Not USDA-certified organic. PHAT and OOZE also declare boric acid and sodium molybdate as their boron and molybdenum sources, and we’d rather you hear that from us.
Worth knowing. We can’t yet tell a living-soil grower what this does to their soil biology. That’s the gap, and it’s the one living-soil growers care about most.
What growers are reporting
In their own words
Quotes come from Bloom’s grower review records. Some are lightly trimmed for length and spelling, with the meaning unchanged; the original messages are on file. Growers in the trial program agreed to their feedback being shared.
“One of the Raspberry Parfait is getting Yellow Bottles and [their organic base], the other is getting [that base] with no other inputs.”

“The Yellow Bottles plant is really showing off… Ultra has really taken over and made a big difference in such a short time frame.”

“The products are easy to use and show great results. My favorite trio complements organic gardening fantastically.”

“I used Ooze in my regimen the last few rounds and noticed a real difference: same clone, same soil and tea.”

“As additions to a compost tea, the Sea Minerals and that line are bad ass.”

“Roots works best as a dip. I mix a 12-gallon batch and dip my teens roots and all. Cuts the smell too.”
