I'm not familiar with HO
. How many watts is that? PC
bulbs seem to be the most popular - but HO
should work just as well.
Canister filters seem to be the filter of choice for planted tanks. Personally, I like to buy a filter rated at double my tank size - but that is just me.
Power heads are not terribly important. I like your substrate choice and amount.
Personally, I think you are better off waiting to get the plants until your CO2
arrives. Then you won't need to spend money on actinic bulbs and low light plants.
What are your fertilizer plans? With a lot of research, you can skip some of the "begineer problems." With fertilizing, it is a very good idea to have a very specific plan, be consistent, and carefully modify the plan as needed.
