More than 1,500 visitors attended the event in June, where the main focus was on plants with 100 UK-based growers exhibiting.
HTA director of business development Tim Briercliffe said: "It went very well. I have never been to a show that's been so positively received."
Commenting on next year's show, he said: "We have more than 60 stands from around 45 companies signed up so far with 50 per cent of our space booked."
Hortipak said it would sponsor the show again.
