Sure thing! Let’s break it down step by step. First, decide how many watts each heater, light, and fan will use. Then, calculate the total by adding them up—say you’ve got a 100 W heater, a 200 W grow light, and a 50 W fan; that’s 350 W total. Next, pick a power strip or breaker that can handle at least 20 % more than that, so a 450 W (or 600 W) rated outlet is safe. Don’t forget the plug‑in voltage: 120 V in the U.S., so you’re looking at about 3 amps (350 W ÷ 120 V ≈ 2.9 A). That’s well under a standard 15 A circuit, leaving room for a surge protector. For efficiency, use energy‑star rated bulbs and a thermostat‑controlled heater to avoid running the lights 24/7. And remember to keep the wiring neat—use labeled cables, avoid overloading the same strip, and check that all connections are tight. That should keep the greenhouse humming, the plants happy, and the risk of a fire as low as a plant's chance of dying from neglect. Feel free to sketch it out with boxes: “Power source → Breaker → Power strip → Heater, Light, Fan,” and add arrows for the flow. If you need more detail on wiring colors or circuit diagrams, just let me know!

Got it, let’s pull it together. For a 15‑amp line, 14‑AWG wire is the standard, but since you’re keeping the breaker at 20 A, it’s safer to use 12‑AWG to give you a margin and reduce voltage drop. Color code the runs: black for hot, white for neutral, green or bare copper for ground—label each wire clearly so no confusion later. Before you flip the switch, use a multimeter to check continuity and make sure the polarity is correct; a quick test of the hot and neutral gives you peace of mind. Once that’s set, we can size the thermal cutoff. A common approach is to set the cutoff a few degrees below your heater’s target temperature—say, if you want the greenhouse at 25 °C, set the cutoff around 23 °C to give a buffer. How does that sound?

All set! I’ll double‑check the heater’s peak current and grab a thermostat that’s tight on the ±0.5 °C range. A 5‑minute delay is perfect to keep the plants from freaking out over a quick spike. Let’s get this greenhouse humming—no detours!
