Some people love to garden with Rise Gardens but don't have a smart phone to help them with feeding the plants. Although nutrient needs of your plants can change through their different stages of life, the general rule of thumb below can help you keep your plants healthy and happy.
This is quick guide to manually add dry nutrients to your garden when you are not using the Rise App or wish to use different nutrients in multiple gardens. As a reminder, dry nutrients and liquid nutrients should not be interchanged in the same garden. According to the University of Arizona's Controlled Environment Agriculture Center, maintaining consistent and correctly balanced nutrient solutions is one of the most critical factors in achieving healthy, productive hydroponic crops.
Personal Garden Manual Dosing
- Add 1/2 tsp of Sprout or Blossom per gallon of water added during weekly care
- The Personal Garden water tank is one gallon, which means 1/2 tsp is the max dose.
- If you are adding only a 1/2 gallon of water, you should add 1/4 tsp of nutrients.
How Do You Manually Dose Nutrients in a Rise Garden or Family Rise Garden?
- Add 1 tsp of Sprout or Blossom per gallon of water added during weekly care
- If you add 3 gallons of water, you'll add 3 tsp of nutrients.
If you are not using the Rise App and only manually dosing your plants, follow this guideline for choosing Sprout or Blossom. Research from Cornell University's Controlled Environment Agriculture program highlights that matching the right nutrient formulation to your plant's growth stage — whether seedling or fruiting — directly supports stronger yields and healthier plants in indoor hydroponic systems like the Rise Garden:
- Sprout: Use this nutrients at the beginning stages of your plants. You'll continue using only Sprout when growing just greens, root vegetables, and herbs.
- Blossom: Switch from Sprout to Blossom when your fruiting plants begin to grow flowers. You'll continue to use Blossom for the duration of your plant growth cycle.
Frequently Asked Questions
How do you manually dose dry nutrients in a Rise Garden?
Manual dry nutrient dosing begins by measuring the correct amount of Rise Gardens nutrient powder using the provided scoop, then dissolving it fully in a small amount of warm water before adding it to the reservoir. Always check the current EC (electrical conductivity) level of your reservoir water before dosing to avoid over-fertilizing. After adding nutrients, stir the reservoir gently and re-test EC and pH to confirm the solution is within the recommended range before sealing the tank.
What are the correct nutrient ratios for Rise Gardens dry nutrients?
Rise Gardens dry nutrients are formulated with a balanced N-P-K ratio optimized for leafy greens and herbs, and the correct dosing amount is specified on the nutrient packaging based on reservoir size. Following the provided measurements precisely is important because even small deviations can shift the EC level outside the ideal range of 1.2 to 2.0 mS/cm for most crops. When in doubt, it is always safer to slightly underdose and adjust upward rather than over-fertilize, which can stress or damage plant roots.
How often should I change the water in my Rise Garden reservoir?
Rise Gardens recommends doing a full reservoir water change every two to four weeks to prevent salt buildup, the accumulation of metabolic byproducts from plant roots, and potential bacterial growth. Between full changes, you can top off the reservoir with fresh water and add nutrients as needed based on EC readings. A clean reservoir is one of the most important factors in maintaining healthy root systems and vibrant plant growth.
What is EC and why does it matter for hydroponic growing?
EC stands for electrical conductivity and is the primary measure of nutrient concentration in a hydroponic solution — the more dissolved nutrients present in the water, the higher the EC reading. Most leafy greens and herbs in a Rise Garden thrive at EC levels between 1.2 and 2.0 mS/cm, with seedlings preferring the lower end and mature plants tolerating higher concentrations. Monitoring EC alongside pH gives you a complete picture of your nutrient solution health and allows you to make precise adjustments for optimal plant growth.
