Query: Bad Agar

The kit looks like good value with everything seemingly included.The problem is that the Nutrient Agar which is included in two bottles, did NOT produce any results.We only needed 9 petri dishes for my daughter's science experiment, so when the first 9 failed we used the remaining in the kit to try again....this time with the second bottle.Again, zero results!Don't waste your time or money on this.Now we are scrambling to source some local agar so we have time to finish my daughter's project before the due date!
