Rootbastic is the partner product to the ever-popular Bloombastic from Atami. Atami state that its a Super concentrated root stimulator with a combination of high NPK bio stimulants and Bio minerals. Its actually one of the best root stims on the market, and one of the cheapest when you look at the dilution rates.
You use it from when your plants have 2 inch long roots for a 3 week period. It will raise your EC slightly so put it into your nutrient tank before your base nutrient, otherwise, the EC will be on the high side. In our experience, you will see very strong root growth within days and after 3 weeks the plant will be set up nicely for its flowering stage.
Highly recommended, excellent value for money.
