Question About Grommets and Buckets

So I grew once in standalone DWC buckets, and decided to convert to a Recirculating system. Did it all up, poured in the water, let it set overnight to see what it would do, and the next morning i had a little bit of water under a couple of the buckets. Not alot, not like a leak. But more like a slow drip.

Now, this thing is a bitch to pull apart.

Question is should I pull it apart and use silicone or something to get those seals tight, or just get drip trays under each bucket and dab up the slight bit of moisture whenever it becomes a problem.
