Atami FAQ's
It is a highly concentrated flowering stimulator, dosed in millilitres per litre of solution rather than by the capful, so a bottle treats far more water than the price suggests. Whether the result justifies the outlay is genuinely worth testing before committing — though note the 100mL trial size is currently out of stock, which makes that harder than it should be.
Early, when root development is the priority — through establishment and the vegetative stage rather than in flower. It comes in 100mL, 250mL and 500mL. As with everything in the Bastic range it is concentrated, so start at the lower end of the recommended rate and watch how the plant responds before increasing.
They are separate products with different purposes rather than a matched pair, so running both at full dose is not automatically the right move. With additives this concentrated, stacking them pushes feed strength up quickly. Introduce one at a time, judge it over a cycle, and keep an eye on your EC as you go.
Rootbastic in 100mL, 250mL and 500mL; Bloombastic in 325mL and 5.5L; Rokzbastic in 325mL, 1.25L and 5.5L. The 100mL sizes of Bloombastic and Rokzbastic are currently unavailable, as is the 1.25L Bloombastic, so the entry point into those two products is larger than it would normally be.
Not at the moment — all three ATA Calmag sizes are out of stock. If you need calcium and magnesium for coco or soft water, our Cal-Mag Supplements collection carries stocked alternatives from other brands. Cal-mag is not brand-specific, so pairing another manufacturer's product with an Atami schedule is perfectly workable.
