iGrowCan Cannabis Grow Kit — From Seed to Harvest in 10 Weeks

The iGrowCan is an all-in-one cannabis growing kit that puts everything you need into a single tin — seeds, soil, nutrients, and instructions. Crack it open, germinate a seed, and you're growing. No prior experience needed, no extra shopping trips, no YouTube rabbit holes at 2am trying to figure out what "coco coir" means. Royal Queen Seeds designed this for people who've always wanted to grow their own but never knew where to start. Ten weeks later, you're trimming your own buds.

What's Inside the iGrowCan

The tin itself is about the size of a large paint can — nothing that'll raise eyebrows on a shelf. Pop the lid and here's what you'll find:

The can itself doubles as your growing container. That's the clever bit — you're not buying a pot separately. The 1.7 litres of coco compost expands when you add water, filling the can and giving the roots somewhere to go. It's a tight space, which is exactly why autoflowering genetics work here. These plants are bred to stay between 30 and 60cm tall, and they'll finish their entire life cycle — germination through harvest — in roughly 10 weeks.

Why the iGrowCan Works for First-Time Cannabis Growers

We've sold grow tents, full lighting rigs, and complete indoor setups for over two decades. And we can tell you honestly: the number one reason people never start growing is overwhelm. They look at HPS bulbs, pH meters, EC readers, ventilation ducting, and they close the browser tab. The iGrowCan sidesteps all of that.

You don't need a tent. You don't need a light timer — autoflowers don't care about photoperiod. You don't need to mix nutrients from three different bottles. The BioGrow and BioBloom sachets are pre-measured at 10g each, so there's no guesswork about feeding concentration. Put the can on a sunny windowsill or a balcony that gets 5+ hours of direct light, and the plant does the rest. We've seen customers grow decent buds on a kitchen counter in Amsterdam with nothing but the kit and natural daylight.

The honest limitation? You're growing in 1.7 litres of medium. That's tiny. Your yield will be modest — think a few grams of dried flower, not ounces. The plant won't reach its full genetic potential because the root space simply isn't there. But that's not the point. The point is you'll learn the entire grow cycle — germination, vegetative growth, flowering, flushing, harvesting, drying — in a single 10-week run. After that, if you catch the growing bug (and most people do), you'll know enough to step up to a proper setup with confidence.

How to Use the iGrowCan

1. Open the can and remove all contents. Set the seeds aside — don't handle them more than necessary. Clean hands, no squeezing.
2. Soak the germination plug in water until it swells up. It has a pre-made hole at the top — drop one seed in, about 1–2cm deep. Cover lightly with the plug material. Keep the plug moist (not waterlogged) in a warm spot, around 20–25°C. A plate with a damp paper towel underneath works well.
3. While waiting for germination (typically 2–5 days), expand the coco compost mix inside the can by adding water gradually. Let it absorb fully — it should feel like a wrung-out sponge, damp but not dripping.
4. Once the seedling has emerged from the plug and shows its first set of leaves, transplant the entire plug into the centre of the coco mix in the can. Don't remove the seedling from the plug — the roots are already growing through it.
5. Place the can in a spot with maximum sunlight. Outdoors in spring/summer is best. Indoors, a south-facing windowsill works. Autoflowers thrive with 18+ hours of light but will grow under natural daylight too.
6. Water when the top centimetre of coco feels dry. Overwatering is the most common beginner mistake — if in doubt, wait another day. The can has no drainage holes, so go easy.
7. Begin adding BioGrow nutrients to your water during the vegetative phase (weeks 2–4). Switch to BioBloom once you see the first flowers forming (usually around week 4–5). Follow the dilution ratios in the instruction manual.
8. Around week 8–9, stop all nutrients and water with plain water only. This is called flushing — it lets the plant use up stored nutrients for a cleaner-tasting final product.
9. Harvest when the majority of the tiny hair-like pistils on the buds have turned from white to amber/brown. Cut the plant at the base, hang it upside down in a dark, ventilated space for 5–7 days to dry. Cure in a glass jar for another week if you can wait that long.

One thing the manual doesn't stress enough: that second seed is your backup. Don't plant both at once in the same can. If your first seed germinates and looks healthy, save the second for a future grow or a mate who wants to try. If the first seed doesn't pop after 5 days, then start the second.

From Our Counter — What We've Learned Selling These

We've been shipping iGrowCans since they launched, and the feedback follows a pattern. People love the simplicity. They love the "gift in a tin" factor — it's genuinely one of the best presents for a friend who's always talking about growing but never does it. The packaging is discreet, the instructions are clear, and the Royal Queen Seeds genetics are reliable. Northern Light Auto and White Widow Auto are the two most popular choices by a wide margin.

The complaints we hear are almost always about yield expectations. If you're expecting to fill a jar, you'll be disappointed. This is a learning tool that happens to produce smokeable flower. Think of it as a bonsai project that you can actually use at the end. The other common issue is overwatering — that can with no drainage holes means you need restraint. Less water, more often, tiny amounts. A spray bottle is your friend for the first two weeks.

Compared to the Seedstockers Cannabis Growkit, the iGrowCan is more compact and more gift-friendly, but the Seedstockers kit gives you a larger pot and slightly more growing medium. If you're buying for yourself and have a bit more space, the Seedstockers kit edges ahead on yield potential. If you're buying as a gift or want the most compact option possible, the iGrowCan wins. Both use autoflowering genetics, both take about 10 weeks.
