Pros
- Noticeably faster growth and healthier, greener plants in hydroponic setups
- Mixes cleanly with no residue and no nutrient burn when measured correctly
- Large multipack supply lasts through many refills
- Works well for a wide range of plants from herbs and lettuce to tomatoes and bamboo
Cons
- Requires two part measuring and mixing at each feeding
- Lacks detailed NPK values and growth stage feeding guidance
- Concentrated liquid needs careful pouring and storage to avoid spills
The Haligo Hydroponics Nutrients set is an 800ml two part A and B liquid plant food designed for AeroGarden and other indoor hydroponic systems. It is ideal for beginners and home growers raising herbs, lettuce, greens, tomatoes, peppers and houseplants in water based setups.
It uses a 100 percent water soluble, pH balanced formula that mixes cleanly without residue. In real world use, growers report noticeably faster growth, greener leaves and stronger root development for herbs, flowers and lettuce with consistent dosing.
The kit includes two bottles plus six refill packs for extended supply, along with a dispensing cup for accurate measuring. Mixing is simple at 5ml of A and 5ml of B per 1L of water, which helps prevent overfeeding when directions are followed.
The two part mixing process requires measuring every time, so it is less convenient than single pour nutrients. It also lacks detailed NPK breakdowns and stage specific feeding guidance for seedlings versus fruiting plants, which experienced growers may miss.
Overall, this is a reliable, easy to use nutrient solution for healthy indoor hydroponic growth. If you want an affordable, versatile starter set that works across systems and plant types, it is a strong choice for continuous growing.
Mix each A and B concentrate with 100ml water to prepare stock solutions as directed.
Add 5ml of A and 5ml of B to each 1L of water in your hydroponic reservoir using the included dispensing cup.
Refresh the nutrient water regularly and watch for steady green growth and strong root development.

TPS Nutrients Liquid Plant Food is an 8 oz concentrated fertilizer made for AeroGarden units and similar indoor hydroponic systems. It is built for beginners and experienced indoor gardeners growing herbs, greens, vegetables and compact houseplants in water based setups.
Its balanced liquid formula is designed to support steady top growth, vibrant foliage and strong root development. In real world use, growers report fuller, wider plants, new leaves in LECA and semi hydro setups, plus healthy starts in AeroGarden units with easy mixing and no strong odor.

The main limitation is size, since the 8 oz bottle suits small indoor kits better than large or multi unit gardens. It also needs regular redosing to keep nutrients consistent, so it is not a set and forget option for soil beds or outdoor containers.

Brand: TPS Nutrients
Model Number: LIQUIDPF8OZ
Form: Concentrated liquid fertilizer
Volume: 8 fluid ounces
Mixing Ratio: 1 teaspoon per gallon of water
System Compatibility: AeroGarden and similar indoor hydroponic systems, including LECA semi hydro
Best For: Herbs, greens, vegetables and compact indoor plants
Primary Uses: Plant growth support and root development
Pros
- All in one nutrient, no need to juggle multiple bottles
- Versatile for hydroponics, coco and traditional soil setups
- Fast dissolving powder with straightforward measuring
- Concentrated formula provides excellent coverage from a single bag
Cons
- Powder must be measured carefully and stirred well to avoid residue
- Formulated for vegetative growth only, flowering plants need a separate bloom formula
- Needs dry, sealed storage to prevent clumping from moisture
General Hydroponics MaxiGro is a stand alone dry nutrient built for the vegetative stage. It is made for indoor hydroponic growers, greenhouse gardeners and soil gardeners who want faster, stronger early growth from seedlings and cuttings.
Its standout strength is the complete, pH buffered nutrition in a single powder. With primary, secondary and micronutrients included, it supports dense foliage, sturdy stems and active root development with a simple 1 to 2 teaspoon per gallon mix.
The water soluble concentrate dissolves well and feeds evenly across drip systems, reservoirs, coco and soil. The 2.2 pound bag is compact, easy to store and far less messy than handling multiple liquid bottles.
The main tradeoff is the powder format itself. It requires accurate measuring and good stirring, and it must stay dry to prevent clumping. It is also strictly a grow formula, so you will need MaxiBloom or another bloom food for flowering.
For growers who want simple, potent and reliable vegetative nutrition, MaxiGro is an excellent value. It is easy to use, highly versatile and proven for vigorous growth in both hydro and soil.

Head-to-Head
Both products aim to keep hydroponic plants green, rooted, and productive, but they take very different paths to get there. Below you will see how General Hydroponics MaxiGro Plant Food and Liquid Plant Food – Fertilizer for AeroGarden compare on formula type, crop range, mixing ease, and storage value for home growers like you.
Formula Type: Dry Concentrate vs Ready To Mix Liquid
General Hydroponics MaxiGro Plant Food is listed as an extremely potent, water soluble dry concentrate that is complete in primary, secondary and micro nutrients. That dry format means you measure powder for each reservoir, which gives you flexible dosing for different growth phases and lets you keep a compact 2.2 lbs bag on your shelf.
Liquid Plant Food – Fertilizer for AeroGarden, by contrast, is a balanced liquid plant nutrition formula that mixes easily with water for indoor hydroponic use. Owners commonly report that the liquid style feels simpler for small tanks because you avoid dissolving powder, while General Hydroponics MaxiGro Plant Food appeals to you if you prefer a potent, stand alone dry nutrient you can dial in.
Compatibility and Crop Range
General Hydroponics MaxiGro Plant Food is described for use with a wide variety of crops in both hydroponic and soil based environments, which makes it the broader pick if you run more than one type of garden. If you move plants between your AeroGarden, a bucket system, and containers in your Garden and Greenhouse space, that flexibility matters for you.
Liquid Plant Food – Fertilizer for AeroGarden is formulated to support plant growth in AeroGarden and similar units, with a focus on herbs, greens, and compact indoor plants. Owners commonly report steady leaf color and root development in countertop systems, while General Hydroponics MaxiGro Plant Food gives you more room to branch out to tomatoes, peppers, and heavier feeders beyond small herb kits.
Ease of Measuring, Mixing and pH Balance
General Hydroponics MaxiGro Plant Food is listed as pH buffered, which is helpful when you mix dry nutrients and want a more stable starting solution. You will still need to stir thoroughly until the powder fully dissolves and check your reservoir, but the buffered design is meant to support superior results without constant adjustment for many home crops.
Liquid Plant Food – Fertilizer for AeroGarden is built for consistent liquid nutrition with easy mixing to support healthy growth and strong root systems. For you as a beginner, that means fewer steps, less residue risk in narrow AeroGarden tanks, and simpler weekly top offs, while General Hydroponics MaxiGro Plant Food rewards you if you are comfortable weighing, stirring, and fine tuning strength.
Container Size, Storage and Long Term Value
General Hydroponics MaxiGro Plant Food comes as a dry concentrate in a larger bag format, so a little powder goes a long way in solution and storage stays compact and dry. If you feed multiple reservoirs or run your system year round, that concentrated style is often seen as the higher end pick for long term use because you are not storing mostly water.
Liquid Plant Food – Fertilizer for AeroGarden comes in an 8 oz bottle that is easy to store beside your unit and pour without extra tools. Owners commonly report it is the more budget conscious and low commitment option for one or two countertop gardens, while General Hydroponics MaxiGro Plant Food suits you better if you want bulk feeding power and fewer reorders over time in your Composting and Soil Health routine.
Which One Should You Get
Choose General Hydroponics MaxiGro Plant Food if you want maximum flexibility across hydroponic and soil based growing and you are comfortable mixing dry nutrients. You are the right fit if you grow heavy feeders, run more than one system, or want a complete primary, secondary and micro nutrient profile in a potent, pH buffered formula that scales from herbs to fruiting crops with careful dosing.
Choose Liquid Plant Food – Fertilizer for AeroGarden if you want the simplest weekly routine for a countertop AeroGarden or similar hydro kit. You are the right fit if you grow basil, lettuce, mint and other compact greens, prefer pour and go liquid feeding for steady root development, and want balanced indoor nutrition without dissolving powder. Another option worth a look is Hydroponics Nutrients for Aerogarden if you prefer a two part A and B kit style.
Who Should Skip Both
If you grow fully outdoors in living soil beds or run large scale aquaponics where fish waste drives fertility, this type of hydroponic feeding is not ideal for your setup. You would be better served with outdoor granular organics or a system specific plan like this fertilizer comparison for acid loving plants rather than either of these indoor hydro formulas, which is not the right choice for soil food web gardening.

Can I use General Hydroponics MaxiGro Plant Food in an AeroGarden instead of AeroGarden branded nutrients?
