I would like to hear peoples opinions and experiences with the new PrimeAgra.
bwester said:Well, I had EXTREME salt build-ups on the new only. Plus every plant in the new started to have severely rotted roots. It wicked entirely too much and seemed to drown the plants. I experienced none of this with the old stuff.
Ron-NY said:The new stuff looks much like hydroton but darker in color. I haven't used either but have used hydroton without a problem.
Ron-NY said:It is mostly spherical except for some broken material. They are not all the same size
bwester said:If your pots have a reservoir did you notice if the water level dropped faster than with the old PA?
--Yes!!! the new ones dried up more than twice as fast!!!
Did you do any kind of test to determine if there was actually more salt build up? Or did you go by only the visible appearance?
--A test was not needed, there was a thick caking of crystals on the top of the media.
How long were the plants that died in the new PA?
--The paphs died fast, the phrags held on for a month or so
Did you also pot up other plants at the same time with the old PA?
--Yes, I am a scientist. I did it very analytical. the same thing to each type. including some divisions of the same plant, one in the old and one in the new
Did all the plants you potted with the new PA die?
--All but one, a phrag.
Did you use coarse or fine PA?
--the standard one ray ships
What size pots did you have the problem with?
--all sizes that ray sells
Where the plants that died new acquisitions or repotted plants you had had for some time?
--both
Where the dead plants transfered from organic media into the new PA?
--yes
What is your fertilizer regime?
--MSU 125ppm N
