A: The Domes will have to be purchased separately. You may search for the domes using product code D940011400-10PK.
A: no, just the usual grooves you find in hydroponic trays
A: Our trays do not have any drainage holes. Our propagation "Inserts" will have the drainage holes.
A: No the bottom is solid -- with ridges to lift your pots off the bottom for drainage. We add water to the tray - not the seedling pots.. If you are looking for trays with liners that have holes, these are not what you are looking for. I use these as trays to hold cow pots for starters. Works very well for our purposes. We picked up clear covers at Home Depot for germination and cycle these trays as the seedlings get larger so we only needed 2 covers.
A: There is no holes for this specific tray.
A: It is approximately 1-1.8 mm. Thank you.
A: Not able to measure the thickness as I do not have a micrometer; however, the description states "Approx: 21" x 11" (top measurement). 20" x 10" bottom of tray" for the size of the tray and the thickness of the plastic is what would be expected for a reusable tray. If you take care of these trays, they will last. I would not put a great deal of weight in these trays. They are meant for starting seedlings and not as planters.
