Start up to 32 plants in this Peat Strip Tray Greenhouse with bonus SUPERthrive sample. 

Jiffy's series of lightweight, plastic planting trays with humidity dome and biodegradable pop-out cells is perfect for growing vegetables, herbs or flowers. The peat strips easily moisten and tear apart when your seedlings are ready to be transplanted to their next home, be it a larger container or somewhere outdoors.

What you'll get:

  • thirty-two (32) celled peat strips for starting up to 32 plants
  • one (1) watertight base tray
  • one (1) clear plastic humidity dome
  • a bonus SUPERthrive sample (kelp-based plant vitamin for vigorous growth)

How to Use:

Prepare Strips:Fill peat pots in the base tray with your sowing medium (not included). We suggest using Premium Seed Starting Jiffy-Mix. Water thoroughly - enough to saturate walls of strips.
Add Seeds:Seeds are not included. Sow your seeds according to the instructions on your seed packet. Place humidity dome.
Germination:Once seeds have germinated, prop dome lid open. When seedlings grow true leaves remove lid completely and place in sunny location.
**Seeds and seed starting mix/soil not included.
