Atami FAQ's
The price is high because Bloombastic is a highly concentrated flowering stimulator, measured in millilitres per litre of solution instead of a capful. One bottle therefore treats a lot more water than the number on the shelf first implies. It is still worth trying before you commit to a large size — the 100mL trial bottle is out of stock at the moment, so that cheaper first step is harder than it should be.
Use Rootbastic at the start of the run, when the plant is building roots — through establishment and the vegetative stage, not once it is in flower. Bottles come in 100mL, 250mL and 500mL. The whole Bastic range is concentrated, so begin at the lower end of the recommended rate and only step up after you have seen how the plant takes it.
They are separate products with different jobs, not a matched pair, so running both at full dose is not the automatic play. Stacking two concentrates like these lifts feed strength in a hurry. Bring one in first, judge it over a cycle, then decide on the other, and keep an EC reading as you go.
Rootbastic comes in 100mL, 250mL and 500mL; Bloombastic in 325mL and 5.5L; Rokzbastic in 325mL, 1.25L and 5.5L. The 100mL bottles of Bloombastic and Rokzbastic are out of stock, and so is Bloombastic 1.25L, so the smallest bottle you can buy of those two is larger than it would normally be.
No — all three ATA Calmag sizes are out of stock at the moment. Growers who need calcium and magnesium for coco or soft water can use the Cal-Mag Supplements collection, which has stocked alternatives from other brands. Cal-mag is not brand-specific, so pairing another manufacturer's bottle with an Atami schedule works fine.
