Should I follow the directions on the bottle or the feeding schedule?

The directions on the bottle are designed for general use. If you’re new to our products and just want to experiment, the directions on the bottle are fine.  We have also developed FoxFarm feeding schedules with more precise details for maximum yields.  Try one of our feeding schedules for an entire grow cycle and you’ll see extraordinary results.

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

Continue to use the feeding directions for Week 12 until harvest.

Can I mix your liquid and soluble fertilizers with other manufacturer’s products?

The FoxFarm family of products are designed with a maximum capacity of nutrient levels.  Mixing them with another manufacturer’s products risks putting our fertilizers out of healthy ratios, which can create nutrient lock-out.  That’s why we suggest keeping the FoxFarm family of products together for optimum results.  Too many ingredients can spoil the soup, create too much salt build-up, and ultimately your plants will suffer.  Our nutrients are created to use together for a complete fertilization program.  Using other company’s products is simply not necessary.  For fantastic results, reference our FoxFarm feeding schedules.

Will Big Bloom^™ clog my pump in my hydroponic system?

Big Bloom^™ will not clog pumps.  Just be sure you shake it well before using, and remember that it needs to be filtered for aeroponic systems.

Using Big Bloom^™ and Tiger Bloom^® forms a white, salty build up on my rock and rockwool.  Should I flush my system?

This residue can be caused by minerals in your community water supply, pH adjustment agents, micronutrient fallout, or organic sources of phosphorous.  This material may not burn your plants, but it can stress them and tie up nutrients.  We recommend that you change your reservoir every two weeks and flush the system with clean water.

Why do I have to adjust my pH so often with Grow Big^® and Tiger Bloom^®?

Both our Grow Big^® and our Tiger Bloom^® formulas include a concentrated micronutrient package that is low in pH.  The advantage to this is that a low pH enables micronutrients to remain stable without any nutrient fallout.  FoxFarm fertilizers are extra-strength, and plants can absorb them easily, but this can cause pH swings.  Regular pH adjustments are recommended especially in early growth stages.  As the plant ages, you’ll notice that the pH will eventually stabilize.

Will I get a chemical taste from the minerals in Grow Big^® and Tiger Bloom^®?

Absolutely not.  Both formulas are made with high-quality fertilizers, micronutrients, and organic catalysts.  You’ll never have to sacrifice flavor when you use FoxFarm products. 

Why do you have Grow Big^® in your feeding schedule when my plants are in the flowering cycle?

Grow Big^® actually helps makes bigger fruit and flowers with sturdier plant structure, so it’s not just for early growth stages.  It will strengthen the plant’s immune system and make it more disease resistant.  By delivering some additional nitrogen through early and midterm flower development, you’ll see that Grow Big^® helps maintain healthier foliage without lanky stretching.  

When combined with Big Bloom^™ and Tiger Bloom^®, Grow Big^® will invigorate the root system and improve nutrient uptake and transpiration rate.

Do I need to leach my hydro system when I use FoxFarm fertilizers?

Yes.  A regular leaching schedule will reduce the risk of mineral salt build-up.  As a result your fertilizers will be used more effectively, and your plants will be healthier overall.  In general, organic nutrients contain little or no mineral salts and don’t require frequent leaching.  However, we recommend leaching the system every two weeks to ensure clean operating conditions.

How often should I change my reservoir when I use FoxFarm fertilizers?

We recommend changing your reservoir every two weeks regardless of your feeding schedule.  This will help reduce disease-causing pathogens and keep your system clean.

Do I need to use chlorine free water when I use your products?

No.  Chlorinated community water does not adversely affect FoxFarm fertilizers.  However, if you expose chlorinated water to the air for several hours, the chlorine will start to volatize and dissipate.  If you’re concerned about the chlorine content in your water and you’re unable to obtain distilled water, this is a good alternative.
