So some weeks back I was in the big city and tried to find jacks hydro.....
the dude says....
we don't carry that brand but we do carry the peters brand.....
So ok..... I bought a bag..... still a bit skeptical I diligently compared the bags.....
The micronutrient package is exactly the same...... not much to say there....
Except for magnesium.....
Lets return to that in a moment.....
The macronutrients are pretty much the same.....
5-11-26 vs 5-12-26 jacks has slightly higher phos than peters....
which is probably not problematical.....
Both are supplemented with calcium nitrate......
the biggest difference therefore is the magnesium......
Its widely reported that with peters magnesium def is not an issue.... because jacks contains high levels of magnesium.....
After considering the labels my general focus has been..... does the use of peters and the lower amounts of magnesium result in any sort of magnesium defs.....
Of course one of the main things about jacks and peters is that they seem to do quite well using tap water...... within reason of course....
tap water will contain calcium and magnesium.......
while I cant say for sure ..... when using RO water.... with tap water the peters has been fine.....
I do in fact keep some epsoms salt just in case..... but the plants haven't complained to this point....
Ive been using around 600 ppm and the plants look perfect.......
I have been doing res changes every two weeks.....
at about a buck per 60 gallon trash can..... cant beat it.......
My motto is something like....
low ppms..... and dump the res regularly.....
Anyone else have any comments about the two ferts????
I certainly cant say which I prefer..... but for me the peters is doing just fine......
