Listen to PlantHed.
And I would avoid adding RW to your system, as it holds even more moisture than HT. Your job is to allow the part of the stem where it meets the root to stay rather dry- this is what PlantHed referred to as the 'crown'. Especially if you are having uncontrolled splashing onto the stem, you will need extra air flow.

That's one of the mediums the other is hydrotone. The roots are popping out the bottom of the Hydro Farm Buckets they were doing really well till I noticed this. Thanks in Advanced GL420 Rating: 5
