White paper 07 · Flower stack · Grower proof series
Phat, Ooze,
Final
Size, then resin, then finish: the order Bloom’s schedule sets, what growers reported running it, and where the proof runs out.

The stack
The back half of the run
PHAT for bulk, OOZE for resin, oil and smell, FINAL to finish. The pattern in the record is clear at the front and thinner at the back: plenty of growers running PHAT and OOZE together, fewer who’ve reported on FINAL.
Growers running PHAT and OOZE together describe getting size and finish, rather than trading one for the other.

What’s actually different
Three things worth knowing
Two jobs, two products
PHAT for size, OOZE for finish. Growers treat them as separate jobs, not alternatives.
A set order
Ultra through the stretch, Phat into bulk, Ooze after, Final to finish.
The last two weeks
FINAL runs in the last two weeks of flower. If you’re weighing flushing against finishing, the independent trials are worth a read.
Worth knowing. Two thirds of this stack is well covered. FINAL has five growers on record, which is a start, not a program. We’d rather say that than pad it out.
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.
“Used Ultra weeks 1–2, switched to Phat weeks 3–4, and these plants are finishing early with major bulk.”

“Everything’s greasy in the tent, from Ooze to Phat to the Sweetener. Week 7 and the buds are so heavy the branches are falling everywhere.”

“Got the branches snapping over the top, heavy from the weight. When y’all say ‘Phat’, ya mean it.”

“The amount of resin production is a very noticeable difference since I added them. They stacked and packed on the resin very fast once I added the PHAT and Ooze.”

“The biggest factor was the Ooze. It laid down some greasy, oily bud and increased the intensity a good amount.”

“Lots of oils, lots of trichome coverage, and amazing smells.”
