ph/mylar

flat white is better than mylar

Def flat white, read and article stating flat white reflects better that foil or mylar. I used to use aluminum foil then changed to flat white and sure enough I couldd see the difference.

agree ... flat white

i think your a little to late to augment your soil.

next time try ffof...

What is your soil? What is the pH (if you know it offhand)? Why are you trying to lower it? What other products are you using?

Never used Espoma Soil Acidifier (I have used a bunch of other Espoma products though). I imagine you can still water in small amounts of it if you really want to lower the pH.

ph in 2 plants are 9.9 and in others its like 5.2 and 4.6

whats ffof?

yes def flat white. ffof is an abbreviation for Fox Farms Ocean Forest Soil

wherecanibuy that and is it expensive

well i have no idea where you are located but a hydro shop would be your best bet or a larger nursery. luckily i have a hydro shop a few blocks from my apartment and it sold for $25 for 2.5 Cu Ft.

i just ordered that ph down product so ill tell you how it goes. and im using fox farm ocean forest btw... "ready to use right out of the bag and ph adjusted to mid 6" my ass...
