We've developed some indicative feeding charts for 20L of substrate below - please note that these are examples only, as each grow will be different depending on strain, plant and grow technique. They should be seen as a starting point.

We've also started using ml/ litre as a measuring method for our products. If converting to tablespoons is easier for you, as 1 UK tablespoon is 15ml, just divide the totals below by 15. The older guides just showing tbsp/gallon are now at the bottom of this page.
