grafting for hydroponic gardening

[cheoreomacv]

Being a new guy at the hydroponic game, I've been reading all I can find in re.
hydro. gardening. I read some articles on grafting tomatoes for hydro. gardening and find that 95% of commercial tomatoes grown in Japan are from
grafted plants. Anyone here had any experience with this topic? I'm thinking
Heirloom tomatoes grafted onto a hardy, prolific, disease-resistant rootstock
like maybe Celebrity. I welcome your comments.
