I regret to say that my poor horticultural research was a waste of time and taxpayers' dollars. If you have large orders of wholesale succulents, such as 4,000 plants, the individual trays could contain less variety. This is why it's a good idea to look online. You are also purchasing plugs and planning to plant them. You want to prevent these effects by placing your plugs in a pot that is able to quickly drain the water. You must ensure that the pot you choose is large enough and well-drained.
