Spider Farmer’s grow light catalogue has expanded considerably over the past few years, and what started as a straightforward two-model range has grown into three distinct series with overlapping wattages, different diode technologies, and a fair number of abbreviations. If you have landed on the Spider Farmer website, looked at the SF1000, SF2000, SF4000, G5000, and SF2000Pro all on the same page, and quietly closed the tab in confusion, you are not alone.
This guide cuts through it. We cover every major Spider Farmer series — SF, G, and EVO — with actual specifications, realistic coverage figures, and clear guidance on which model fits which tent size and growing goal. We also take an honest look at when Spider Farmer is the right call and when a competing brand makes more sense.
How the Spider Farmer Lineup Breaks Down
Spider Farmer organises its LED grow lights into three main groupings, each aimed at a different buyer profile.
SF Series is the original line and remains the most widely sold. These lights use Bridgelux LEDs (2026 models) depending on the specific version and stock. They are passive cooled (fanless), straightforward to use with a single dimmer knob, and priced to compete with budget and mid-range LED brands. The SF series covers wattages from 100W to 650W and is the right starting point for most hobby growers.
G Series is Spider Farmer’s newer generation aimed at growers who want more control. G series lights use Bridgelux diodes with the highest LED density in the Spider Farmer lineup, and they add built-in WiFi and Bluetooth with app control via the Spider Farmer smartphone app. This allows scheduling, dimming, sunrise and sunset simulation, and remote monitoring. The G series is priced above SF equivalents but below premium horticultural brands.
EVO Series refers to lights built around Samsung LM301H EVO diodes, which are the most efficient single diodes Spider Farmer uses, rated at 3.14 µmol/J per diode. The EVO designation appears in model names like the SF2000Pro. These lights retain the passive cooling and simple dimmer of the SF series but push efficiency higher than standard Bridgelux models.
Understanding this split makes every subsequent comparison easier: SF for value, G for smart control, EVO for maximum efficiency.
SF Series Models Compared
The SF series is where most buyers start and, for many home growers, where they finish. Here is what each model offers and who it suits.
Spider Farmer SF1000
The SF1000 is Spider Farmer’s entry-level panel and the natural first grow light for someone setting up a small tent. Running at 100W, it is designed to flower a 2×2 ft (60×60 cm) space and can stretch to veg coverage of 3×3 ft at lower intensity. PPE sits at 2.5 µmol/J, which is competitive for the price tier.
The 2026 version uses Bridgelux LEDs and delivers a full-spectrum output covering 660nm red, 3000K warm white, and 5000K cool white — suitable for both vegetative growth and flowering. Passive cooling keeps noise at zero.
For a 2×2 tent growing herbs, chillies, or a couple of autoflowering plants, the SF1000 is a capable and affordable option. It is not the light to push into a larger space; at 2×2 ft flowering coverage it is correctly specified for a small tent.
Best for: 2×2 ft tents, first-time growers, seedlings and herbs
Spider Farmer SF2000
The SF2000 steps up to 200W and extends the flowering footprint to a genuine 3×3 ft, with veg coverage reaching 4×4 ft at reduced intensity. PPE is 2.7 µmol/J on the Bridgelux 3030 diodes, and the light runs fanless with a single dimmer for simplicity.
For a detailed breakdown of real-world performance, our Spider Farmer SF2000 review covers the light in full, including spectrum data, heat output, and how it compares to similarly priced alternatives. The short version: it is one of the most consistently recommended mid-range grow lights available, with strong PPFD uniformity across a 3×3 footprint.
The SF2000 is the sweet spot in the Spider Farmer range for most hobby growers. A 3×3 tent with the SF2000 is a setup that will grow herbs, vegetables, and even flowering plants to a high standard without requiring any supplemental lighting.
Best for: 3×3 ft tents, versatile home growing, herbs through fruiting plants
Spider Farmer SF4000
The SF4000 jumps to 450W and targets a 4×4 ft flowering footprint, expandable to 5×5 ft for vegetative growth. PPE is 2.7 µmol/J with a PPF of 2083 µmol/s and dimensions of approximately 44 x 45 inches, designed to fill a standard 4×4 tent evenly.
At this wattage, the SF4000 moves into serious hobbyist territory. It replaces 600-800W HPS in terms of canopy penetration and is a good choice for anyone running a 4×4 tent who wants high yield potential without paying premium prices for brand-name horticultural LEDs. Heat management is handled by a large aluminium heat sink with no fans and no noise.
Best for: 4×4 ft tents, serious hobby growing, high-yield setups
Spider Farmer SF7000
The SF7000 is the top of the standard SF series, running at 650W with Samsung LM301B diodes and a photon efficiency of 2.8 µmol/J. The PPF reaches 1786 µmol/s and the commercial coverage footprint is 5×5 ft.
The SF7000 uses a foldable panel design rather than the rigid bar format of the smaller SF models, which makes it easier to store and transport. It is aimed at experienced growers or those transitioning from HPS who want a large-footprint LED that delivers serious intensity. At 650W it does run warm, so tent ventilation needs to be sized appropriately.
Best for: 4×4 to 5×5 ft tents, advanced growers, transitioning from HPS
G Series: Smart Control for Home Growers
The G series sits above the SF range on features rather than raw wattage. The key addition is built-in WiFi and Bluetooth connectivity paired with the Spider Farmer app, which gives full dimming control, scheduling, and sunrise/sunset simulation from a smartphone. You can also daisy-chain up to 60 G series units for simultaneous control, a feature more relevant to small commercial grows than home tents, but worth knowing if you ever plan to scale up.
All G series lights use Bridgelux diodes at the highest LED density Spider Farmer offers, with PPE figures at or above 2.85 µmol/J. This makes them more efficient than the standard SF series on paper, and the app features make them meaningfully more practical for growers who want automated schedules.
G3000 (300W)
The G3000 runs at 300W and covers a 3×3 ft flower footprint. It bridges the gap between the SF2000 and SF4000 in terms of wattage, and the app control makes it a better fit than those models for growers who want a more automated setup. The PPE of 2.8 µmol/J sits above the SF2000’s 2.7 µmol/J, with stronger canopy penetration thanks to the higher diode density.
Best for: 3×3 ft tents, growers who want app scheduling, mid-wattage upgrade from the SF2000
G5000 (480W)
The G5000 is the most popular G series light, running at 480W with a 4×4 ft flowering footprint and PPE of 2.85 µmol/J. The PPF reaches 1420 µmol/s. For a 4×4 tent where you want both high output and smart scheduling, the G5000 is a strong alternative to the SF4000. The price premium over the SF4000 reflects the app connectivity and higher diode efficiency.
Best for: 4×4 ft tents, growers wanting smart control, efficiency-focused setups
G8600 (800W)
The G8600 tops the G series at 800W, covering 4×4 to 5×5 ft with a PPE of 2.85 µmol/J and PPF of 2283 µmol/s. Daisy-chain control of up to 60 units from a single app makes this the option for anyone scaling beyond a single tent. For home growers, the G5000 is usually sufficient; the G8600 becomes relevant at a semi-commercial scale.
Best for: Large 5×5 ft spaces, semi-commercial setups, maximum output with smart control
The G series lights are a genuine upgrade over the SF range for growers who will use the smart features. If you set up a schedule once and leave it running, the extra cost over an SF model is easy to justify over the life of the light.
EVO Series: Maximum Efficiency
The EVO designation in Spider Farmer’s range refers to models using Samsung LM301H EVO diodes, rated at 3.14 µmol/J per diode — the most efficient individual LED chip Spider Farmer currently uses. EVO models are sold at a premium over Bridgelux-equipped equivalents but deliver a measurable step up in efficiency.
SF2000Pro
The SF2000Pro pairs EVO diodes with a 200W power draw, a fanless design, and a full-spectrum output covering 660nm red, 3000K and 5000K white, and 760nm infrared. The system PPE reaches 2.7 µmol/J, with a flowering footprint of 2×2 ft and vegetative coverage of 3×3 ft.
The SF2000Pro’s flowering coverage (2×2 ft) is smaller than the standard SF2000 (3×3 ft) despite matching it on wattage. This is intentional: the EVO diodes are arranged for intensity over footprint, driving harder into a smaller area rather than spreading over a wider canopy. It is a better choice for growers who need maximum intensity in a compact space rather than those trying to cover a full 3×3 ft efficiently.
The SF2000Pro is also compatible with the GGS Smart Controller bundle if app-based scheduling matters to you.
Best for: 2×2 ft tents needing high intensity, growers prioritising efficiency per watt

Which Spider Farmer Should You Buy
Here is a practical guide by tent size and growing goal.
2×2 ft tent: The SF1000 is the default choice. If you want higher intensity for dense canopies or demanding plants, the SF2000Pro delivers more punch in the same footprint at higher cost.
3×3 ft tent: The SF2000 is the most popular choice and represents excellent value. Step up to the G3000 if app scheduling matters and the budget allows. For more comparisons in this category, the best grow lights for indoor plants guide covers options from multiple brands.
4×4 ft tent: The SF4000 handles most situations well. The G5000 is the upgrade path if you want smart controls and slightly better efficiency. Budget a minimum of 400W for a 4×4 tent covering fruiting plants.
4×4 to 5×5 ft tent, high intensity: SF7000 or G8600 depending on whether app control matters to you. Both deliver the wattage needed for a large footprint; the G8600 costs more but adds WiFi and Bluetooth.
Herbs and houseplants only: The SF1000 is ample for a 2×2 space. The dimmer allows you to reduce intensity for delicate seedlings and sensitive houseplants.
Mixed use (veg then flower in the same space): Any Spider Farmer model with a dimmer handles this, which is all of them. Set to 75% for vegetative growth and increase to 100% for the flowering stage. Use a grow light timer to automate photoperiod switching without guesswork.
Spider Farmer vs Competitors
Spider Farmer does not exist in a vacuum, and there are scenarios where a competitor makes more sense. Here is an honest comparison of the major alternatives.
Spider Farmer vs Mars Hydro
Both brands compete directly in the mid-range LED market, often within a few pounds or dollars of each other at equivalent wattages. Mars Hydro lights generally feature more aggressive heat dissipation, which can extend LED lifespan in warmer environments. Spider Farmer consistently scores higher on photon efficiency (µmol/J), meaning more usable light per watt consumed.
For most UK and US home growers, the difference in real-world results is marginal. Both produce excellent crops. Spider Farmer tends to edge ahead on efficiency metrics; Mars Hydro often leads on raw yield data from community growers. The right choice often comes down to which specific wattage and form factor works for your tent.
Spider Farmer vs HLG (Horticulture Lighting Group)
HLG is a premium US-made brand that consistently tops efficiency charts and is widely used by serious hobbyists and small commercial growers. The trade-off is price: HLG lights typically cost around 150% more than a comparable Spider Farmer model.
If budget is the constraint, Spider Farmer is the better value. If you are growing high-value crops and want the absolute best diodes and build quality available at the hobbyist level, HLG justifies the premium. For a full comparison of both brands, the best LED grow lights guide covers the top options across price tiers.
Spider Farmer vs ViparSpectra
ViparSpectra is the budget-tier option. Efficacy typically runs around 2.2 µmol/J compared to Spider Farmer’s 2.5-2.85 µmol/J range, meaning more electricity consumed for the same amount of usable light. ViparSpectra works for low-intensity growing — houseplants, herbs, seedlings — but for any serious canopy coverage, the efficiency gap compounds over time on your electricity bill. Spider Farmer is worth the modest price difference for most growing applications.
When to choose another brand: If you need a fixture that meets specific certifications for a commercial or institutional setting, HLG and other premium brands are more likely to hold the relevant marks. For home growers, Spider Farmer covers most use cases at a better price point than the premium tier while outperforming budget options on every meaningful metric.
Frequently Asked Questions
Are Spider Farmer Grow Lights Good for Beginners?
Yes. The SF series lights are among the most beginner-friendly LED grow lights available. The single dimmer knob, passive cooling (no fan noise), and clear spec sheets make them straightforward to use. The SF1000 or SF2000 are the standard starting points for new home growers.
What Diodes Do Spider Farmer Lights Use?
It depends on the model. 2026 SF series lights use Bridgelux LEDs. The G series also uses Bridgelux at higher density. EVO series lights (like the SF2000Pro) use Samsung LM301H EVO diodes, which are rated at 3.14 µmol/J per diode and represent the most efficient chips in the Spider Farmer lineup.
How Far Should a Spider Farmer Light Hang from Plants?
Distance depends on the light’s wattage and the plant’s growth stage. As a general starting point, hang 18-24 inches above the canopy during flowering for most SF models, and 24-30 inches during vegetative growth to avoid light stress. Reduce distance gradually as you dial in the correct intensity for your specific plants.
Can Spider Farmer Lights Replace HPS?
Yes, for most home and small-scale growing. The SF4000 (450W) effectively replaces 600-800W HPS in terms of canopy output, with lower heat output and electricity consumption. The SF7000 and G8600 are suited to replacing larger HPS setups.
Do Spider Farmer Lights Work with Timers?
Yes. All Spider Farmer lights work with standard plug-in timers. G series lights add built-in scheduling via the app, which removes the need for a separate timer. The GGS Smart Controller accessory can also add scheduling to compatible SF and EVO series lights.
Is the G Series Worth the Extra Cost over the SF Series?
If you will use the app features, yes. Automated scheduling, sunrise/sunset simulation, and remote dimming are practically useful for busy growers and for setting up photoperiod switching without manual intervention. If you prefer to manage your grow manually, the SF series delivers comparable light output at a lower price.
Conclusion
Spider Farmer makes a strong case across every price tier in the home growing market. The SF series covers most hobby growing needs at prices that undercut premium brands by a significant margin, the G series adds smart app control for growers who want automation, and the EVO series pushes efficiency to the highest level the brand currently offers.
For most growers the decision is simple: match the wattage to your tent size (roughly 30-50W per square foot of flowering canopy), choose SF if budget is the priority and G if app control matters, and add the GGS Controller if you want scheduling without stepping up to the G series.
