Spider Farmer SF1000 EVO LED Grow Light – 100W Samsung Diodes

The Spider Farmer SF1000 EVO LED Grow Light is the definitive leap your indoor grow needs to stop wasting electricity and start producing professional-grade buds. This 100W full-spectrum board is designed to replace hot, inefficient lights, giving you maximum yield in spaces up to 90x90 cm with minimal heat and noise.

Are you tired of seeing your electricity bill skyrocket while your plants struggle with heat stress and airy buds? Relying on old HPS systems or cheap, inefficient lights often leads to inconsistent results, forcing you to battle high temperatures and waste money on cooling equipment just to keep your crop alive.

The frustration of putting in months of work for a mediocre harvest is real. Every degree of excess heat burns off terpenes, and poor light spectrums result in fluffy flowers that lack potency. Continuing with outdated tech means you are literally burning money every month for a subpar product.

The SF1000 EVO solves this instantly. With its high-efficiency Samsung diodes and passive cooling, you get deep light penetration and zero noise, turning every watt into dense, resinous flowers. It is the smart, efficient solution that pays for itself in energy savings and harvest quality.

Before starting your grow with the SF1000

Setting up this panel is incredibly simple, but to get the beast performance, you need to prepare your space correctly. This light is ideal for a 100W Grow light LED setup in a 60x60 cm tent for flowering, or up to 90x90 cm for the vegetative stage. Before you plug it in, make sure your ventilation is adequate, although this LED runs cool, fresh air exchange is vital.

• Check your tent size: Perfect for 60x60 cm to 90x90 cm spaces.
• Plan the height: You will need adjustable ratchet hangers (usually included) to move the light as plants grow.
• Substrate matters: Since LEDs evaporate less water than HPS, use a high-quality Universal Substrate with good drainage to avoid overwatering.
• Timer setup: Have a reliable timer ready for your 18/6 (veg) and 12/12 (flower) cycles.

During cultivation: Mastering the light

Once your seeds pop, the Spider Farmer SF1000 becomes your best ally. The built-in dimmer allows you to adjust intensity without changing the spectrum. Start low (around 40-60%) during the seedling stage to avoid stress, and crank it up to 100% as you enter the flowering phase. The Samsung diodes provide a rich, full spectrum (3000K, 5000K, 660nm Red, and IR) that mimics natural sunlight.

You will notice that your plants develop shorter internodes and greener leaves compared to other lights. Because the heat output is low, you can bring the light closer to the canopy—about 30-45 cm during peak flowering—to maximize photon absorption. Keep an eye on your temperature; since the LED doesn't emit radiant heat like an HPS, you might need to slightly reduce your extraction speed to maintain the perfect VPD (Vapor Pressure Deficit).

After: Results and maintenance

When the cycle ends, the results speak for themselves: sticky, rock-hard buds with a terpene profile that hasn't been degraded by heat. Growers often report yields up to 2.5 grams per watt with this fixture. Once you harvest and grab your Pruners, you will see the difference in density immediately.

Maintenance is minimal. Since it has no fans, there are no moving parts to break. Simply wipe the diodes gently with a dry, soft cloth between grows to remove any dust or residue that might block light. That’s it—it’s ready for the next run.

Advantages and benefits of the Spider Farmer SF1000

• High Efficiency: Uses only 100W to replace a 250W HPS, slashing your electric bill.
• Samsung Diodes: Top-tier chips ensure high PAR output and long lifespan.
• Full Spectrum: Includes IR and Red light to boost photosynthesis and heavy flowering.
• Silent Operation: Fanless design means zero noise, perfect for stealth grows.
• Dimming Control: Adjust light intensity easily for every stage of growth.
• Daisy Chain: Connect multiple units together for larger grow spaces without messy wiring.
• Cool Running: Reduces the need for powerful air conditioning or massive extractors.

Frequently Asked Questions

What is the recommended hanging height?

Generally, hang it at 60-75 cm for germination, 45-60 cm for vegetative growth, and lower it to 30-45 cm for flowering to maximize intensity.

What size grow tent is this light best for?

It is optimized for a 60x60 cm (2x2 ft) flowering footprint. For vegetative growth only, it can cover up to 90x90 cm (3x3 ft) effectively.

Does it come with a warranty?

Yes, Spider Farmer lights typically come with a manufacturer's warranty (check specific terms upon purchase) and are built to last over 50,000 hours.

Can I use this for autoflowers?

Absolutely. The full spectrum is perfect for the entire life cycle of autoflowering strains, from seed to harvest.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested the SF1000 in a small closet setup, and honestly, it’s a game-changer for micro-growers. What I love most is the peace of mind—it runs so cool that I don't worry about heat stress even in summer. I usually keep it at 80% power during late veg and only push it to 100% when the flowers start forming pistils. The density of the buds I got from a couple of autoflowers was surprising for just 100W. It’s a solid, reliable piece of gear that just works.
