Bio Nova K20 final reviews and its price of sale

Lack of potassium is not the much comon one in-between cannabis plants. Even though it is not rare to notice these type of lack due an unbalanced substrate ph, a poor quality of water used or due a bad use of nutrients. In any case, K-20 is a supplement that acts as an additive of potassium, solving quickly any deficiency of this element.

Furthermore than being a deficiency solver, we do think it is interesting to use K20 as a potassium additive during late flowering phase before flushing. We made our test and the extra source of potassium not only enlarges the crop, but also improves quality. We have noticed an increase of bud density, that manifests as larger flowers, denser with higher dry-weight, besides more resin, taste and flavor.

Once the efficiency of K-20 hs been reviewed, now it's time to talk about its price. In this case, as it happens with other Bionova products, we can only congratulate this brand for selling a high quality product, for an average price, being highly concentrated (specially if we compare concentration with products from competitors). Focussing the point: If dosages are 10-20 times lower and the price is only slightly higher than other products in market the conclusion is clear: K20 has a sale price much cheper than any other product with similar functionality in market. Do not hesitate to try it and see the results in your own garden.
