DWC or Top Fed hydroton buckets

Tired of hand watering soil and would love to start hydro, but I had bad experience with DWC, root rot, had to start the entire grow over cos of it. Had read a lot of positive things about plants in buckets full of hydroton with top fed drippers, this system seems bulletproof except one thing, I live in high humidity area, and sometimes it could be weeks when humidity is over 90%. So dehumidifier is a must if I choose top fed hydroton, right? Otherwise algae starts to grow on top and boom, root rot? DWC on other hand needs water chiller cos it's hot where I live. Both water chiller and dehumidifier are pretty much same wattage.

Will I still get algae on top of hydroton if run a sterile nutrient solution all the time? If so, will it lead to root rot?

Guys what method would you choose in my situation?

Top feed heres mine check it out

If you use a sterilizing agent it will kill the algae also in a top feed system.

If you cover the top of your buckets so no light hits the surface of you grow medium you wont get algae. No need to treat for it
