Grow A 5-0-2 Limestone City Nutrients

Grow A is excellent for houseplants and tropicals such as monstera, philodendron, pothos, alocasia, anthurium, bird of paradise, palms, and fiddle leaf figs. The combination of nitrogen, calcium, magnesium, and micronutrients helps promote larger leaves, stronger stems, vibrant green growth, and healthy root systems. It’s especially useful during active growing periods when tropical plants are producing new foliage.

Great for

Cannabis
Houseplants
Tropical plants
Tomatoes
Peppers
Cucumbers
Lettuce
Herbs
Annual flowers
Hydroponic gardens

How to Use

Mix 2 mL Grow A and 2 mL Grow B per litre of water
Feed once per week or with every feeding during vegetative growth
Always add Grow A and Grow B separately to water
Never mix concentrates together before dilution

Honestly, the Grow A 5-0-2 + Grow B 1-5-8 combination is excellent for houseplants and tropicals.

Unlike many general-purpose houseplant fertilizers that only provide NPK, this two-part system supplies:

Nitrogen for lush, green leaf growth
Calcium for stronger stems, roots, and new growth
Magnesium for chlorophyll production and deep green foliage
Phosphorus for root development
Potassium for overall plant health and vigor
Essential micronutrients including iron, manganese, zinc, copper, boron, and molybdenum

For tropical plants that are grown primarily for their foliage, that’s a very complete nutritional package.

Especially Great For

Monstera
Philodendron
Pothos
Alocasia
Anthurium
Syngonium
Ficus
Bird of Paradise
Palms
Dracaena
Schefflera
Hoya

Why Tropicals Like It

The added calcium and magnesium make a huge difference. Many tropical plants are heavy feeders and often show:

Yellowing leaves
Weak new growth
Brown edges
Slow growth

when calcium and magnesium are lacking. The Grow A + Grow B formula addresses those needs while also providing a full suite of micronutrients.

Houseplant Feeding Recommendation

For most indoor tropicals:

2 mL/L Grow A
2 mL/L Grow B

Use every second watering for average houseplants, or every watering for fast-growing tropicals during spring and summer.
