Frequently Asked Questions

Common questions about cannabis grow equipment.

What grow lights are best for cannabis?⌄

LED grow lights have become the dominant choice for indoor cannabis cultivation — they run cooler, use less power, and modern full-spectrum designs rival HPS output. For a small tent (up to 4×4 ft), quality LED brands like Spider Farmer, Mars Hydro, or HLG deliver excellent results. HPS lights are still used in large commercial operations where initial cost matters more than running costs. CMH (ceramic metal halide) sits between the two: better spectrum than HPS, lower heat than HID. For autoflowers and seedlings, even basic quantum board LEDs work well.

How do I choose the right grow tent size?⌄

Match your tent to your plant count and training style. A 2×4 ft tent fits 2-4 plants trained with LST or SCROG. A 4×4 ft tent is the most popular size for home growers — enough room for 4-6 plants with a good yield. For perpetual grows (veg + flower simultaneously), you need two separate spaces. Tent height matters as much as footprint: cannabis can double in height during flowering, so a 2m (6.5ft) tent is the minimum for tall sativas. Key brands include Gorilla Grow Tent, Secret Jardin, and Mars Hydro FC tents.

Do I need a CO2 controller for my grow room?⌄

Only if you're running a sealed room with CO2 supplementation — and even then, CO2 injection only helps when all other factors (light intensity, temperature, nutrients) are already optimised. Most home growers don't need CO2 controllers. What you do need is a basic environment controller for temperature and humidity, and a good exhaust fan with speed control. If you're growing in an open tent with passive intake, a simple plug-in fan speed controller is sufficient. Dedicated CO2 controllers become relevant at commercial scale or in high-performance sealed grow rooms.

What nutrients do cannabis plants actually need?⌄

Cannabis needs three primary macronutrients — nitrogen (N), phosphorus (P), and potassium (K) — plus secondary nutrients like calcium and magnesium, and a range of micronutrients. During vegetative growth, plants want high N. During flowering, P and K increase while N drops. Most nutrient brands offer a two-or-three-part base system that covers the full life cycle. Popular choices include General Hydroponics, Advanced Nutrients, Canna, and BioBizz. Simpler is usually better for beginners — a complete one-part formula reduces the risk of over-feeding.

What meters and monitors should every cannabis grower have?⌄

At minimum: a pH meter, an EC/TDS meter for nutrient concentration, and a digital thermometer/hygrometer for temperature and humidity. A pH of 6.0-7.0 (soil) or 5.5-6.5 (hydro/coco) is critical — incorrect pH is the most common cause of nutrient lockout. For EC, most strains do well at 1.2-2.0 EC in veg and 1.8-2.4 EC in flower. Quality pH meters from brands like Bluelab or Milwaukee instruments are worth the investment — cheap pH pens drift and give false readings. A VPD chart app or controller (like the Inkbird or AC Infinity) makes dialling in environment much easier.
