Plagron Seedbox
The Plagron Seedbox is a complete germination kit ready to use straight out of the box.

Seeds typically sprout within a few days. Order at Plant & Flower.
Plagron Seedbox – complete germination kit for a hassle-free start
No separate purchases needed: the Plagron Seedbox bundles everything in one box. A growing tray with clear dome, 12 germination plugs and a 250 ml bottle of Plagron's Seedbooster. Follow the included instructions and seeds typically sprout within days. Browse our full propagation range in the cloning and propagation category.
What is inside the box?
The sturdy tray doubles as a mini propagator — its transparent lid traps warmth and humidity. The 12 plugs expand as they absorb the Seedbooster solution. Pour the full bottle into a measuring cup, add 250 ml of lukewarm tap water, stir gently and distribute evenly over the plugs. Once absorbed, plant your seeds 5 mm deep in each plug.
The Seedbooster advantage
The Seedbooster is more than fertiliser. It contains an anti-rot enzyme that gently penetrates the seed coat to trigger germination, even in older or harder-to-sprout seeds. The result: higher success rates and uniform early growth within the first few days.
Reusable tray, expandable system
Once your first batch has sprouted, the tray and lid are ready for reuse. Fill them with loose plugs — such as Root Riot cubes — and Seedbooster Plus for your next round. The kit is a perfect entry point that grows with your setup.

How many seeds can I germinate in the Plagron Seedbox?
The Seedbox contains 12 germination plugs, so you can germinate up to 12 seeds at once. This is enough for a compact starter session. The tray is reusable, so you can run additional rounds with fresh plugs and Seedbooster Plus.
What is the difference between the Seedbooster in the kit and Seedbooster Plus?
The Seedbooster included in the Seedbox is a 250 ml bottle mixed in full with 250 ml of water for the 12 plugs provided. Seedbooster Plus is a highly concentrated 10 ml bottle dosed at 7 drops per litre, designed for standalone, repeated use across multiple sessions.
Is the Plagron Seedbox tray reusable?
Yes, both the tray and the transparent dome are designed for reuse. Plagron suggests combining them with loose germination soil or plugs and Seedbooster Plus for subsequent sessions. Clean the tray between uses for best results.
