Block Clean Spray 750ml Essentials

Block Clean Spray 750ml Essentials is a ready-to-use cleaning spray formulated to maintain cleanliness and hygiene in hydroponic grow media such as rockwool and rooting cubes. Over time, salt buildup, algae growth, and organic residue can form on grow blocks, negatively impacting root health and nutrient absorption. Block Clean Spray dissolves and lifts these contaminants without damaging delicate root systems or seedlings.

Ideal for propagation cubes and early-stage plants, this spray promotes better root oxygenation and helps prevent mould or fungal issues caused by surface buildup. It’s especially effective in high-humidity environments or systems with frequent feeding.
