Im currently trying to grow radishes in my raft system. This is the first time I'm growing radishes on my rafts. I was wondering if it is possible to grow? I already started the plants and I'm about 15 days from harvest (following seed instructions). I notice that the radishes are growing half way in my 2 inch net pod and half way out. Is this how it grows on rafts? The harvest size is supposed to be a pound and the size of a baseball or bigger. Thank you for any info you can give.
