Cultiwool 100x100x65 (4") Short Cube - Large Hole (38/40)

• Your Launchpad for Strong Roots: This 4-inch block acts as the ultimate bridging step. If you started your seeds or clones in a standard 1.5" starter plug, this "Large Hole" version is tailor-made to let that plug drop right in seamlessly, eliminating transplant shock entirely.

• Perfect Balance for Your Watering Routine: Because it is a "short" profile cube (65mm tall instead of the standard 75mm), it holds a slightly different moisture gradient. It is designed to drain efficiently while holding onto the precise water-to-oxygen ratio your root zones crave, preventing the roots from suffocating or rotting.

• Complete Steering Control: Since Cultiwool is completely inert, you are the master chef of your garden. The cube won't alter your pH or sneak in unexpected nutrients, meaning whatever premium fertilizer or EC recipe you feed your plants is exactly what they will get.

Whether you are running an automated drip system, a flood-and-drain table, or just hand-watering a small tent, these blocks give you clean, commercial-grade predictability on a personal scale.
