Windowsill tray with lid

The complete package for windowsill growing: a proper base tray topped with a fitted lid that turns the whole thing into a mini greenhouse. Warmth stays in, humidity builds up, and your seeds or cuttings get exactly the conditions they need to get going — all without needing a single square inch of extra kit. Lift the lid off once things are established, and you've got a tidy little tray ready to do it all again.
