He factored the percentages down to their lowest common denominator for direct comparison. V+B is stronger, but they are pretty similar in composition. For example, if you take a fertilizer that has a 3-1-2 ratio and another that has 15-5-10, they have the same ratios of NPK but the second fertilizer is three times as strong.
Yeah i see what he did but truly saying that maxigrow is similar enough to v+b that plants wouldn't notice a difference. Now I'm not sure that is true. Again the ratios ARE different and i wouldn't use maxi grow from start to finish. Maxi bloom is the better option. Just ask the kiss folks.
