The last few times I've been trying another product that has been hard to find in my area, Elevation Organics "Desert Nectar". I like the fact that both use the Yucca extract, and neither will do any damage to the microbial activity in the soil. The Desert Nectar also has a bit of humic acid as well. (a plus) Both do a good job.
I'm not saying the other products don't do well, but I haven't found any specifics on their ingredients, and like the "organic" approach.

As Emilya says, the FF nutes NEED to be flushed. Using the two products above have made the process pretty simple. When I first began using them, I would evaluate the effectiveness of the flush by taking ppm readings of the runoff. Without the "rinse" products, the volume of water needed for an effective flush was significantly more.

Just noticed this is in the hydro section, drew225! Hope we don't piss anyone off.
Oops. Thats what I get for trying to do things right. I used the advanced search with the key word "flush" I was trying to avoid posting before doing a search. I didn't even pay attention to what section this was in
drew225 Reviewed by drew225 on . flushing To flush or not to flush, that is the question. My last 2 harvests i flushed with clearex one week before harvest. During that last week, just ran pHed water thru the system. This harvest i am considering not using clearex but rather gradually reducing the nutrient mix during the final weeks and then just water for a couple of days. Any opinions would be appreciated.
