Aptus Tent Set Basic 5x50ml - Full-Cycle Booster Kit for a Small Tent
Best for: growers running a single small tent (around 1m² of canopy) who want to try the whole Aptus booster range in one go without buying five full-size bottles.
Our thoughts
This is a proper taster pack rather than a gimmick - five genuine Aptus concentrates, just in small bottles so you're not stuck with 90% of a litre you'll never use if it turns out not to be for you. Good way to test a full feeding range on one small crop before committing to full-size bottles.
The Tent Set Basic bundles five Aptus concentrates at 50ml each: Startbooster (root and growth stimulator), Regulator (nutrient uptake and stress support), K-Boost (potassium-led maturation stimulator), Top Booster (flowering and maturation stimulator) and Super-PK (phosphorus and potassium bloom stimulator). Together they're designed to cover a plant from early growth through to the end of flower on a scale suited to one small tent.
Each product is used alongside your normal base feed rather than replacing it - they're concentrated additives, so the 50ml bottles go further than the size suggests once diluted at typical rates of 0.5-2ml per litre depending on the product and growth stage.
How it compares
Booster starter kits are a common way for nutrient brands to get new growers into a full range.
- Similar concept to Canna and House & Garden starter/trial packs, which bundle a base range in smaller bottles.
- Aptus's range leans more on stage-specific boosters (five separate functions) rather than a simple two-part grow/bloom split.
- Buying the set works out cheaper than buying five full-size 500ml or 1 litre bottles individually to sample the range.
If you only want one or two of these products long-term, buying the individual full-size bottle is usually more cost-effective once you know which ones you'll actually reuse.
Usage guidance
Introduce each booster at the growth stage it's designed for rather than dosing all five at once.
Vegetative growth
Use Startbooster to support root and shoot development, and Regulator to help the plant handle stress and improve nutrient uptake.
Early to mid flower
Bring in Top Booster to kick-start and intensify the flowering response.
Late flower
Add Super-PK and K-Boost as phosphorus and potassium demand rises through ripening, tapering off before harvest per the product-specific dosage guide.
Dilution
Follow the dose rate on each individual bottle - rates vary by product and by growth stage, typically in the 0.5-2ml per litre range.

Who this is for
- Growers with one small tent who want a complete stage-by-stage feeding range in one purchase.
- Anyone curious about the Aptus range who doesn't want to commit to full-size bottles yet.
- Growers who like a structured, product-per-stage approach rather than a two-bottle grow/bloom system.
Best suited to a single small-tent grow used as a trial run for the wider Aptus range.
Our take
It's a sensible way to try five products for less than buying them individually, and it's sized honestly for the crop it's meant for rather than leaving you with unused stock. One we sell a lot of for growers just getting into Aptus.
If a 1m² tent is what you're working with, this covers a full cycle without overbuying, at a price that makes sense.
