Yep, that is what I do and what I argued for in http://www.aquaticplantcentral.com/forum/viewtopic.php?t=505.Error said:This makes me wonder, if limiting P produces slower but still decently healthy growth... might one want to limit it to decrease momentum
I suppose that would work fine but that isn't my point here. Regardless of the light level chosen one can use P availability to regulate desired growth rates and plant appearance. This doesn't neccesarily mean running P down to limited levels is a goal. Rather one uses P to regulate N/P ratios in order to achieve particular goals of appearance or growth rate.plantbrain said:Why not less light then, rather than less PO4?
