If you can get those trays just purchase a bucket company kit and the a condensate pump and your set. Are you going to hand feed? If so you might as well deal with the runoff By hand as well so just have the buckets drain into a bucket or a tote then put a small pond pump in it and turn it on to drain the bucket. If you’re going to automate the feed and I highly recommend you do with either drip rings or stakes or however you want to do it. Makes life way easier in long run unless you like missing feed solution daily.
many options out there for a DTW coco system that are pretty cheap and easy to use
