Feeding Schedules for Indoor Hydroponic

Indoor Hydroponic Intro

Hydroponics is a grow technique under horticulture and a subset of hydroculture which involves growing plants without soil by using nutrients rich solution in flow. Using Hydroponics is beneficial to you but unless you use proper food and water with prior feeding schedule, it remains futile. 

If you are growing indoor plants, then it seeks much of your attention like, you have to make up your own feeding schedule that will give you good quality of yield and healthy plants and a method of cultivating plants using many mediums that help plants to get direct contact with nutrients and their means of delivering into the water reservoir while stimulating growth. 

Advantage of indoor hydroponic:

  • Indoor plants helps reduce stress level
  • Save space
  • Good for water conservation
  • Faster growth
  • Nutrient control
  • Healthier lifestyle

Disadvantage of indoor hydroponic:

  • Expensive set up
  • Vulnerable to power outages
  • Required constant monitoring and maintenance

Tools helpful for maintaining indoor plants 

When you have the right tool at hand, growing is lot easier than you think! Here are some common tools and equipment used in growing the plants indoors.

pH tester

When you supply water to plants, you should check for pH of water whose range be compatible with your plant type. Properly balanced pH will reduce the chances of future mishap.  

pH strip can be used for water testing as of pH test kit, according to product direction. Dip a litmus strip into sample water and compare the result with the chart provided with the kit.

If pH is too high you only need to add pH-low substituent to water. Use product sparingly to avoid over-correcting.

Stir the water carefully with the mix in the solution.

Measuring spoons

Accuracy and precision are very important when it comes to feeding mixing. This will be used for adding nutrients or feeding solutions or creating solutions.

Epsom salts

Adding ¼ teaspoon in every feeding it will help increase the level of magnesium in turn help growth.


Help you to dissolve the nutrients and salts assigned to your plant and it will easily absorb to your plant.
Gather all these things for feeding your plant properly to avoid difficulties. 

Basic hydroponic set-up:

Plant food

Buckets for use

4 x amnesia haze

1 x 400 watt LEDs for the vegetation phase.

1 x 600 watt LEDs for the flowering phase

Environmental spaces for every growing phase and careful maintenance.

The 2 phases of plant growth are growing phase and flowering phase, for which you need to follow the conditions to regulate, maintain. But it may differ for what type of plant you are grow.

Environment condition for Growing Phase

Light Amount/ Distance /Duration:  50% of lamps on (400 Watt MH)/40 inches between plant and lamp/18 hours a day

Day/Night Temperature:  73/64 F°

Water temperature:  70 F°

Humidity:  80%

pH level:  5.8

Environment condition for Flowering Phase

Light Amount/Distance/Duration: 100%/20 inches/12 hours per day

Day/Night Temperature:  77/65 F°

Humidity:  70%

pH level: 5.8

Indoor feeding schedule

Different nutrients have their different chart like dutchpro,cultured biologix. Typically the nutrients are absorbed from soil but the indoor plants in grow media rather than soil, needs nutrients in the proper manner so you have to schedule them to help it grow. 

There are two types of nutrient available: dry and liquid portions. This always dissolves in grow media giving better results because plants absorb quickly.

Once you are done with preparation, you will find that your DIY schedule differs with the one in the manufacturer’s suggestions. 

So that you have an idea of a good general feeding schedule for your hydroponics, we have put together one sample mix (note: this is just a general and may not work for all plants or hydroponic gardens, not every nutrient mix):

1st Week = 5ml

2nd Week = 10ml

3rd Week = 10ml

4th Week = 10ml

The remaining schedules are all 10ml.


The nutrients that you brought in grow stores will also carry feeding schedules and instructions. Few such nutrient products of feed describe are like, 

Canopy crop

Power Si will help reduce the salt built-up and dehydration of crops. And is proven to build a stronger cell-wall by decreasing susceptibility to various disease-causing pests, while turning the plant stem stronger and thicker. 

Cultured Biologix

They help vegetative growth promoter and early flower booster composed of a proprietary blend of enzymatically hydrolyzed plant proteins (derived from non-GMO, organic soybeans), chelated calcium, and organic aloe Vera extracts. It is plant-based nitrogen feed and a natural calcium source that boosts nutritive value in plant growth. 


Water Base Feed for plants during the flowering phase growing or flowering phase in hydroponics or coco. Requires 4 bottles of nutrients at times, for better yield. The self-created recipe helps in heavier, denser and bigger fruits than before. 

These are some brand that provide their nutrients feed chart:

Cultured Biologix


General hydroponics

Notes and tips

  • Make sure your plant gets at least 6 hours of sunlight in a day.
  • Start with a small quantity of plants then you get an idea for perfect scheduling.
  • Check pH regularly.
  • Set your scheduling cycle so it can be easy for you to feed.
  • If you overfeeding your plant turning yellow leaves.

Final Thought 

When you begin gardening or growing commercial plants you need to know the nutrient feeds and their schedule at their respective phases (i.e., growing to flowering phase) that way you get an idea about the plant nutrient they need and how to manage their feed intake.

Feeding schedule is must when it comes to indoor planting, when you over feed or miss a follow up, it will affect your plant yield. Many brands provide their own feed charts so whenever you buy any product(nutrients) please make sure you follow their chart.
