  • For best results use with FoxFarm fertilizers

Why is there a hole in my cap?

We utilize two different caps: vented and non-vented. There is a small hole in the top of our vented cap that allows for airflow in and out of the bottle to keep it from collapsing or distorting during shipping or on shelves.

How often should I feed and water my plants? How much water should I use?

We recommend feeding your plants up to twice a week, ensuring that they receive a regular watering in-between feedings. When feeding and watering your plants, you will want to apply enough water or solution so that 10-15% runs out the bottom of the container. Once the top 2-3” of media have dried out, it is time to water again.

Can I mix dry and wet fertilizers together?

You can use our dry, soluble and liquid fertilizers in combination with each other. Please refer to our feeding schedules for comprehensive instructions.

What do I do if my grow cycle is longer than your feeding schedule?

For longer vegetative cycles repeat week four of our feeding schedule, and for longer flowering and fruiting cycles repeat week twelve of the feeding schedule.

How do I mix FoxFarm fertilizers together?

When you mix FoxFarm fertilizers together, do not combine them in their undiluted form. Begin with a gallon of clean water. Add each fertilizer product to this gallon of water in the recommended doses. If growing in soil, adjust the pH of your nutrient solution to between 5.6 and 6.8, and if growing hydroponically, adjust your pH to between 5.8 – 6.3. For best results follow one of our FoxFarm Feeding Schedules.


Use your preferred FoxFarm potting soil when transplanting seedlings into larger containers. We recommend a two gallon size or larger.FOR BEST RESULTS:Feed up to two times per week. Maintain a pH of 5.6 to 6.8 to prevent nutrient lockout and reduce stress on plants. Never mix pure concentrates together; always add water first. Should plants show signs of stress or color irregularities, flush your system. When using coco-based media, flush every two weeks during the flowering cycle as coco has a tendency to retain unwanted salt residue more than peat-based soils.
