Product description
Atami RootBastic 250 ml – highly concentrated root stimulator for the first weeks of veg
RootBastic is dosed so low that even the smallest bottle covers a lot of plants. The 250 ml size is the place to start for a single tent or for growers trying the Bastics root stimulator for the first time.
What's inside
Atami RootBastic is a concentrated NPK root stimulator from the Bastics range, with NPK 4-14-4. Minerals, trace elements, a plant extract and amino acids, with phosphorus as the key nutrient, help your plants build a dense, well-branched root system with plenty of fine roots in the first weeks of veg. It suits hydro, coco and soil.
How far 250 ml goes
At 0.1 to 0.3 ml per litre, this bottle treats roughly 830 to 2,500 L of nutrient solution. Build up over three weeks with a 50 L tank (0.1, then 0.2, then 0.3 ml/L) and one run uses only about 30 ml. That gives you around eight runs from this bottle.
Dosing small amounts
Doses like 1 ml in a 10 L can are easy to overshoot, so use a 1 ml syringe rather than a measuring cup. Shake the bottle first. Use RootBastic during the first three weeks of veg, increasing the dose week by week. It raises the EC of your base solution, so measure after mixing and lower your base feed slightly if needed.
