Product description
Atami RokzBastic 325 ml – PK 10-20 finisher for a couple of tents
Once you know you like the way Atami RokzBastic firms up the last weeks of flower, the 325 ml bottle is the sensible next step for a home grower with one or two tents. You get the same potassium-led formula: PK 10-20, a P:K ratio of 1:2, 1% iron and biostimulants.
Why growers use it
Late in flower, plants shift their demand towards potassium while they fill out and ripen. RokzBastic answers that with a clean, concentrated blend that is very low in sodium and chloride, so it will not load your root zone with unwanted salts in the weeks that count.
How many runs is that?
At 0.5–1 ml per litre, the bottle covers about 325 to 650 L of nutrient solution. If two tents use around 100 L each over the ripening period, you have enough for one or two full runs.
Dosing
Mix it into your base feed during the last 4–6 weeks of flower and ripening, preferably following BloomBastic. A small measuring cylinder makes it easy to scale between watering cans and a small tank. Check EC after adding, since RokzBastic raises it.
