What are the downsides to flood and drain?

My story battling alge...

Starting off, like you see in the second picture, we decided to waste the time and money to build 6 cloning tables, I decided to skip the cloning tables altogether. By slicing a small slit in the insulation block, I stuck the clone straight into the block, and it went great! No discoloring, no stress, and no transfers needed. But as you see in the 1st pic, alge on the block was still occurring obviously, so then covered it all with weed block, it made things super clean, no nats... just more time consuming...

Klemo this is a ton of clones LMAO. I had a very similar lid with holes at one time, ended up starting all types of veggies in it. I however switched to using it as a flood and drain placing small cups in the holes. I wonder where you will be planting all these clones jeez!
