The Phytonaut range from Zamnesia is built around one simple idea: match the wattage to your tent footprint, and let the diodes do the work. Four sizes, four tent footprints, no guesswork. Whether you're running a single-plant 60x60 in a cupboard or a full 120x120 in the spare room, there's a Phytonaut that fits without cooking your canopy or shorting your harvest on PPFD.
Below is the wattage chooser we send people to when they ask "which one do I buy?" It's the fastest way to get from tent size to cart.
| Phytonaut model | Tent size | Good for | Why it fits |
|---|---|---|---|
| Phytonaut 120W | 60x60 cm | First-time buyers, single-plant grows, cupboard setups | Enough PPFD to flower one plant without scorching; runs cool in a small footprint |
| Phytonaut 240W | 80x80 cm | Hobby growers running 2-4 plants, the sweet-spot tent size | Even coverage across the canopy; the size most home growers actually end up buying |
| Phytonaut 320W | 100x100 cm | Intermediate growers stepping up from an 80x80 | Holds intensity at a wider footprint; dimmable down for veg |
| Phytonaut 480W | 120x120 cm | Experienced growers wanting serious yield in one tent | Drives a full 1.44 m² canopy in flower without needing a second panel |
Read the table by tent footprint first, wattage second. Buying a 480W for an 80x80 is like putting a motorway engine in a Fiat 500 — you'll dim it down to 240W anyway, so just order the 240W and save the cash.
Phytonaut panels are fanless. That matters more than people realise. No fan means no moving parts to fail, no noise in a bedroom grow, and one less thing pulling dust into your tent. Heat dissipation happens through the aluminium body — passive cooling that's been the standard on serious panels for years.
The diodes are a mix of Sanan and Osram chips covering the full spectrum from blue through deep red. Full-spectrum means one light handles veg and flower — you don't swap bulbs or buy two fixtures. The IP65 splash rating means a leaky reservoir or an overzealous foliar spray won't kill your light. We've seen growers lose entire panels to one spilled top-feed; IP65 is the kind of spec you only appreciate after the fact.
Dimming is dual — a manual rotary knob on the panel itself, plus a 0-10V port if you want to wire it into a controller later. Beginners use the knob; growers running multiple tents wire the 0-10V into a master controller. The 54,000-hour rated lifespan works out to roughly 12 years of 12/12 flowering cycles. You'll replace the tent before you replace the light.
Start with your tent. If you haven't bought one yet, the 80x80 with the Phytonaut 240W is the combination we'd buy for ourselves — enough room for 2-4 plants, manageable in a spare room, and the 240W panel is the most forgiving on training mistakes. Beginners often want to "future-proof" by buying the 480W now; don't. Get the wattage that matches your tent and dim it if you need less.
Intermediate growers stepping up from a small tent should order the Phytonaut 320W with a 100x100. The extra footprint pays off when you start running more plants or wider training methods like ScrOG. Advanced growers chasing yield in a single tent buy the Phytonaut 480W for a 120x120 — at that point you're driving a proper canopy and the 480W has the PPF to back it up.
When in doubt, get the 240W. It's the size most growers end up with anyway.
The Phytonaut 240W. It's matched to the 80x80 footprint and runs the full veg-to-flower cycle without needing a second light. If you ever drop down to fewer plants, the rotary dimmer lets you pull it back without losing spectrum.
Yes. All four Phytonaut models are fanless and cooled passively through the aluminium body. No fan, no noise, no moving parts to fail. Good if your tent shares a wall with a bedroom.
Yes, both ways. There's a rotary dimmer on the panel for manual control and a 0-10V port if you want to wire it into a grow controller. Drop the 240W to around 40% for the first two weeks, then ramp up as plants establish.
No. Phytonaut panels are full-spectrum across the Sanan and Osram diodes, covering the whole cycle from seedling through harvest. One light, one cycle — that's the point of full-spectrum LEDs.
Yes. The 320W is the right match for 100x100. The 480W is built for 120x120 footprints — running it over a smaller canopy means you'll dim it constantly and waste capacity you paid for.
