Really don’t need the mackerel nutrient.

Grow pepper Grow!!!

Need pen ph meter,looking for grow lights

Active Aqua grow flow elbow hardware kit

Works great....threads seem solid,and the plastic the product is made from is of good quality.

Autopilot Advanced Recycling Timer

This timer is easy to set,and the photo cell picks up on low light to let it know it's daytime in case you use that feature...this timer seems to be well made as well....I recommend this timer.
