Yesterday I transplanted melon starts that I began in Oasis cubes.
The transplantation to Dutch buckets took its toll on watermelon seedling especially. I think the problem was that I did not wet the perlite before I transplanted them and it dehydrated the seedlings.
The mixture in the Dutch bucket is about 20% coconut coir an 80% percent perlite. My hope is to advance a melon harvest by about 2 months so that I can have melons ready by May instead of July.
