Hey Chris...The algorithms definitely are in place, but the cultivation needs for each species of grass is what is needed. Those are the variables that fit into the algorithms. Also, I wanted to know if there was a specific variety of grass Ellen or yourself have in mind to help prioritize which cultivar of grass. I have a long backlog of plants that we are chipping away at. If I knew which specific grass or any plant for that matter, I would bump it up to the front of the list. I do wish it was easier to add plants, but there is quite a bit of research that needs to be done for each entry. I definitely would not want to add a new plant entry with cultivation needs that were not accurate which may result in sub par plants (or even worse: plant death). I hope this is helpful. If you do have any new plants that you would like to see in the database, please feel free to post in these forums. I read them all the time and am happy to accommodate our users. Cheers...Robby
