I bought Bacopa from Petsmart, and I have like gigantic plants now from the original offering. Here are some tips, I visited a few Petsmart stores.
GO FOR THE INSIDE PACKETS.
If you go through them, they put the older ones in the FRONT. The ones in the back are MUCH MUCH fresher. Also, a few of them are quite old, they will be evaporated, or even dried up. You can also tell if something has been sitting, because the plant actually grew a bit in the package. The ones I bought was in the back, had a lot of Gel Material, and was quite short. The freshest. Just my 2 cents.
Also, I compared the TOPFIN stuff to the stuff in Petco, and I can say the Petsmart stuff is a lot better
I also prefer the TOPFIN Petsmart stuff because it is GUARANTEED NO SNAILS (it says it right on the package)
