The ROOT!T Large Value Propagator Tray & Lid Kit is a purpose-built, unheated cloning and seed starting system engineered to maintain the ideal high-humidity microclimate required for successful plant propagation. Consisting of a robust, heavy-duty bottom tray and a matching crystal-clear humi-dome lid, this large-format kit delivers exceptional environmental control for raising delicate seedlings or striking fresh cuttings.

The crystal-clear lid maximises light penetration from overhead grow lamps or natural sunlight while keeping moisture locked inside to prevent delicate foliage from wilting. It features adjustable dual-vent sliders, allowing home growers to fine-tune internal humidity levels and manage vital fresh air exchange as roots develop. The heavy-duty bottom tray is entirely watertight to protect your growing area from spills, and it is specially sized to accommodate a wide variety of propagation media, including 24-cell or 60-cell rooting trays, coco coir plugs, or rockwool blocks.

Product Features

Dual Adjustable Air Vents: Features two rotatable dial vents on the lid to effortlessly control internal humidity levels and fresh air circulation.
Maximum Light Transmission: The high-clarity, UV-stabilised humi-dome ensures your young plants receive full-spectrum light without sacrificing moisture retention.
Heavy-Duty Construction: Moulded from shatter-resistant, robust plastics designed to endure multiple growing seasons without cracking or warping.
Optimised Moisture Management: The deep bottom tray prevents waterlogging by safely containing run-off, maintaining a healthy root zone environment.

Step-by-Step User Guide

Follow this guide to set up your propagator and manage humidity levels for maximum rooting success.

Step 1: Initial Setup

Wipe the inside of the bottom tray and clear lid with a damp cloth to remove any transit dust.
Place your pre-hydrated plugs, rockwool blocks, or filled cell trays flat into the bottom tray.
Ensure there is no standing water pooling over the top of your rooting plugs.

Step 2: Sowing & Siting

Insert your freshly prepared cuttings or newly sown seeds into the growing medium.
Place the clear lid firmly onto the bottom tray, ensuring it sits flush within the rim to trap moisture.
Move the propagator into a warm, bright position out of direct summer sun, or place it beneath a dedicated LED grow light.

Step 3: Closed-Vent Phase (Days 1 to 3)

Fully close both top vent sliders to trap maximum humidity (aim for 90% or higher).
This extreme humidity prevents fresh cuttings from drying out while they lack roots to drink water.
Lift the lid once a day for 30 seconds to wipe away excess condensation and refresh the internal air.

Step 4: Hardening Off Phase (Days 4 to 10)

Open both vents slightly (about a quarter open) to allow a small amount of fresh air in and lower the humidity.
Check your growing plugs daily; add water to the base of the tray if the plugs begin to feel light or dry.
Gradually open the vents wider over the next few days to get the young plants used to normal room air.

Step 5: Rooting & Removal

Once you see visible roots breaking through the sides of the plugs, open the vents completely.
Remove the lid entirely for a few hours at a time to check if the plants wilt.
If they remain upright without the lid, they are fully acclimatised and ready to be transplanted.
