We've developed some indicative feeding charts for 20L of substrate below - please note 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 use ml/ litre as a measuring method for our products. If using tablespoons, as 1 UK tablespoon = 15ml, just divide the totals in the tables by 15 to get the dosage in tablespoons.
If you have any queries about feeding, don't hesitate to get in touch via email or chat, giving us a few details about your grow and we'll get back to you with our recommendations.
In this section we set out a few conversions for you - we work to UK/ Imperial measurements.
Number of spoons in a bag
Bag weights (grams)
Although we do our very best to ensure each product is as standardised as possible, please be aware that the weights may differ by up to 10% from those illustrated as our products are dependent on ingredients received from suppliers and also factors such as temperature, moisture content etc. when bagged.
