The SUPERNOVA® Solution

Supernova® liners are programmed liners with a treatment of intensive lighting, spacing to encourage growth, pinching, PGRs and heat – all of which help the liners flower faster and consistently with thicker branching. Growers will enjoy:

  • Shorter crop times
  • Consistent and faster flowering
  • Less pinching and fewer PGRs
  • Increased branching

Brian Bourdon

"Supernova® liners are faster to flower and need less attention, so they are a great way to save production time and labor. That’s why these liners can benefit growers of all sizes. Standard-sized liners typically take 7 to 10 weeks to be ready to market in a 4-in. container, but Supernova Liners are ready much more quickly. They take only 4 to 5 weeks to finish, and need no pinching or PGRs, which is why many growers have been able to finish plants yearly and add an extra turn every season."
