- Do I need to soak the rockwool before use?
- Yes. Rockwool is alkaline out of the bag, so soak the cubes in pH-adjusted water before planting. Many growers also add a light nutrient mix for cuttings.
- Will the net pots fit standard hydroponic lids?
- The cups are the common small net-pot style used in propagation trays and bucket lids with matching holes. Check the hole diameter of your system before ordering.
- Can I use these cubes for soil seedlings too?
- Yes. The cubes work as a starting plug, and you can transplant the cube and seedling into soil once roots show through the sides.
- What is not included in the kit?
- The set is just the 72 rockwool cubes and 72 net pots. You supply the tray, water, nutrients, light and a reservoir or bucket.
- Are the cubes reusable?
- No. Rockwool compresses and breaks down after one grow, and old cubes can carry root pathogens. Use fresh cubes each cycle.
