Bloom Yellow Bottles FAQ's
Grow A&B in veg and Flower A&B in flower is the usual pairing. Euro A&B is the other base mix, for growers who prefer that formulation. All three are two-part: you add A and B separately and never mix the concentrates undiluted, so incompatible elements stay apart until they hit the water.
No — stacking every bottle is the usual mistake on a range this deep. Around fifteen supplements exist so you can tune a feed, not because every garden needs every one. Start with a base, a root product and one flowering additive, judge that over a full cycle, then add another. Watch the EC as the stack grows.
Most of the line is sold in 300mL, 1L and 2.5L, and Pre, Florigen and Phat also come in 15L. The 300mL bottles are how you trial additives on a range this wide without buying litres. Scale up only the products that earn their place.
All three are marine-derived, but they do not do the same job. Seaweed and Seafuel are extract-based inputs aimed at vigour and stress tolerance; Sea Minerals supplies trace elements from a marine source. They sit alongside each other rather than replacing one another, though most growers pick one instead of running all three on a full additive schedule.
In the closing stage of the cycle, as the name says. Final is the finishing bottle in the Bloom range — the point where the aim shifts from bulking to finishing the crop cleanly. It is sold in 300mL, 1L and 2.5L. Use the brand's schedule for when to bring it in; it is not a stand-in for a plain-water flush.
