Ok. I have a substrate of playsand.osmocte should last you 3-6 months depending on the substrate, if its gravel based substrate then it should last about 3 months, it seems to last longer in dirt type of substrate. make sure they are buried deep into substrate otherwise you will get ammonia/nitrate spikes and do not overdose them, add under the rooted plants. good luck
Alright, thanks for the info. I'll remember that! And yes, they did get here fast!I'm glad you got them! That was fast!
I just push them down all the way to the bottom next to the plants I'm trying to feed. They seem to last about 3 to 6 months like stated above.
Every once in a while you will see that one of the pellets (yellow) make it to the surface. You can either take tweezers and push it back down or remove it and throw it out.
