Here is one link that might help. You'll have to copy and paste it. in greenhouse production.pdf

A word you might find helpful in doing google searches is "fertigate" - it just means to add fertilizer to a drip line. Click on the link below for more search results.

RE: npk

Thanks for the help

RE: npk

Roses grow best with a fertilizer with the N-P-K ratio of 1:2:1, 1:2:2 or 2:3:1. The lower proportion of N (Nitrogen), promotes the appearance of lush leaves in plants.

RE: npk

I thought nitrogen promoted vegetative growth, Lucas?

RE: npk

Yes Grizzman, the vegetative growth increases with the amount of nitrogen; but the best NPK fertilizer ratio is 1:2:1. Too much nitrogen may end up with beautiful green leaves and fewer blooms.

RE: npk

Here`s one that may be worth a try. Its specifically for roses grown commercially in rockwool or perlite.

NO3: 182
NH4: 11
P: 54
K: 234
Mg: 24
Ca: 180

EC: 2.0
