Bootstrap Farmer 1020 Humidity Dome Tray Lids 2.5"

Absolutely perfect. Domes for half the price barely last a season, these will serve my flower farm where I start 90+ trays of soil blocks indefinitely. A must have.

Perfect fit

These are so much better than the thin lids that generally come with tray/insert sets. Fit is much better around the edges than thin lids. Bit of an investment but if you start seeds every year its worth it.

Tough plastic Lid

The quality of this product as well as the others that we ordered through Indoor Farmer was incredible. Heavy duty and will last numerous seasons. You get what you pay for and these are premium products that taper difficult to find in Canada. Would recommend to everyone.
