• Natural seaweed based feed
• Makes up to 800 litres

The best foliar feed around.

Mix up the concentrate with water as advised on the tub and spray the solution onto the undersides and tops of your leaves using a spray gun. This gets nutrients straight to the leaves.

A great job to do in the morning when the stomata (tiny holes in leaves) are open and receptive to water and moisture. 

Spray guns, otherwise known as diffusers, are easy to buy or recycle old spray-gun cleaners, thoroughly rinsing out the gun first.

Perfect for leafy crops like lettuce and cabbage and an immediate tonic for plants such as tomatoes.
