Easy Grow Tablets by Royal Queen Seeds
Easy Grow Tablets are slow-release nutrient tablets designed to feed your plants throughout the entire vegetative phase — up to twelve weeks from a single application. Made by Royal Queen Seeds, each colour-coded brown tablet dissolves in water and delivers a precise blend of hydrolysed protein, humic acid, seaweed, and essential minerals directly to your root zone. No measuring, no mixing multiple bottles, no weekly feeding schedules. One tablet, one dissolve, and your plants are sorted for the veg stage.
Why Easy Grow Tablets Beat Bottled Nutrients
Bottled nutrient systems work, but they demand attention. You're measuring EC, adjusting pH, mixing Part A before Part B, flushing when you overfeed. For a first-time grower — or honestly, for anyone who just wants healthy plants without the chemistry set — that process creates more problems than it solves. We've seen growers burn entire crops because they misread a syringe at week three.
Easy Grow Tablets take a different approach. The slow-release formula means nutrients become available gradually, matching the pace your plants actually absorb them. No salt buildup in the soil, no lockout from sudden pH swings. The humic acid (20% Leonardite-derived) conditions the growing medium and feeds soil biota — those beneficial microorganisms that break down organic matter into forms your roots can actually use. The result is a root zone that's alive and working for you, not just a passive container for liquid feed.
The honest limitation? These tablets are designed specifically for the vegetative stage. Once your plants flip to flower, you'll need a separate bloom nutrient. Royal Queen Seeds makes an Easy Bloom counterpart for exactly this reason. But for veg — from the moment your seedling sprouts until the day you switch the light cycle — one tablet handles everything.
What's Inside Each Easy Grow Tablet
Six ingredients, each with a specific job. No fillers, no mystery "proprietary blends." Here's what you're actually feeding your plants:
| Ingredient | Percentage | Role |
|---|---|---|
| Hydrolysed protein | 30% | Amino acid source — feeds soil microbes and provides plant-available nitrogen |
| Leonardite humic acid | 20% | Conditions soil, improves nutrient uptake, stimulates root development |
| Lithothamnium seaweed | 20% | Natural source of calcium, trace minerals, and growth-promoting compounds |
| Calcium bi-carbonate | 15% | Calcium supply and pH buffer |
| Potassium sulfate | 12% | Potassium for cell structure and water regulation |
| Magnesium sulfate | 3% | Magnesium for chlorophyll production — prevents yellowing between leaf veins |
The 30% hydrolysed protein is the backbone here. It breaks down into amino acids that soil bacteria convert into nitrogen — the primary driver of vegetative growth. Combined with 20% Leonardite humic acid, you're building a root zone that's biologically active rather than just chemically fed. The 20% Lithothamnium seaweed (a calcified red algae harvested from the ocean floor) adds over 70 trace elements that most synthetic feeds miss entirely.

Complete your grow setup: pair Easy Grow Tablets with Easy Bloom Tablets by Royal Queen Seeds for seamless nutrition from seedling to harvest. If you're starting from scratch, grab a grow kit or growing medium alongside your nutrients — healthy roots in good soil make these tablets work even harder.
How to Use Easy Grow Tablets
- Wait until your seedling has sprouted and shows its first set of true leaves. Don't feed the tablet to seeds or freshly germinated sprouts — they don't need external nutrients yet.
- Drop 1 Easy Grow Tablet into 3-5 litres of water. Use room-temperature water, not cold from the tap. Stir occasionally over a few minutes until the tablet has fully dissolved and the water turns a dark brown.
- Water your plants with the Easy Grow Tablet solution as you normally would — saturate the growing medium until you see a small amount of runoff from the bottom of your pot.
- Continue using the nutrient water mix throughout the entire vegetative stage. The slow-release formula delivers nutrients for up to 12 weeks, so there's no need to increase concentration or add supplementary feeds.
- When your plants transition to the flowering phase (either naturally or by switching your light cycle), stop using Easy Grow Tablets and switch to a bloom-specific nutrient like Easy Bloom Tablets.
What Easy Grow Tablets Won't Do
Transparency matters more than a sales pitch. These tablets handle vegetative nutrition brilliantly, but they're not a complete lifecycle solution on their own. You'll still need a bloom nutrient once flowering begins — the NPK ratio in these tablets is weighted towards nitrogen and vegetative growth, not the phosphorus and potassium demands of flower production.
They're also designed for soil and coco growing. If you're running a deep water culture or NFT hydroponic system, slow-release tablets aren't the right format — you need soluble nutrients that you can control in real time. Stick with liquid hydro nutrients for recirculating systems.
And one more thing: "up to twelve weeks" means exactly that. In hot climates or with heavy-feeding genetics, the nutrients may deplete faster. Watch your plants. If you see lower leaves yellowing before week ten, a light top-up feed won't hurt.
Frequently Asked Questions
Can I use Easy Grow Tablets in hydroponics?
No. These are slow-release tablets designed for soil and coco substrates. The gradual nutrient breakdown relies on soil biota, which aren't present in hydroponic reservoirs. Use liquid hydro nutrients for DWC, NFT, or ebb-and-flow systems.
How many Easy Grow Tablets do I need per plant?
One tablet dissolved in 3-5 litres of water is enough for the entire vegetative phase of a single plant. For multiple plants, scale up proportionally — two plants means two tablets in 6-10 litres.
Do Easy Grow Tablets replace pH adjustment?
The calcium bi-carbonate (15%) acts as a mild pH buffer, which helps stabilise the root zone. Most soil growers won't need to adjust pH separately. If you're growing in coco, it's still worth checking your runoff pH occasionally.
What happens if I use Easy Grow Tablets during flowering?
The high nitrogen content promotes leafy vegetative growth, which isn't what you want during flower. Excess nitrogen in bloom can delay bud development and reduce final yield. Switch to a bloom-specific nutrient like Easy Bloom Tablets when flowering begins.
Are Easy Grow Tablets organic?
The formulation contains organic-derived ingredients — hydrolysed protein, Leonardite humic acid, and Lithothamnium seaweed make up 70% of the tablet. The remaining 30% includes mineral salts (potassium sulfate, magnesium sulfate, calcium bi-carbonate). It's a hybrid formula rather than a fully certified organic product.
Can I combine Easy Grow Tablets with other nutrients or supplements?
Royal Queen Seeds designed these tablets to provide complete vegetative nutrition without supplements. Adding extra nutrients risks overfeeding and salt buildup. If you're using Easy Grow Tablets, skip the CalMag, the root stimulators, and the growth boosters — the formula already covers those bases.
How long does it take for the tablet to dissolve?
Give it 3-5 minutes with occasional stirring. The tablet is dense and chalky by design — that density is what allows the slow-release mechanism. The water will turn a dark tea-brown colour when it's ready to use.
