Si todoa son adaptables. Solo comprueba que tu extractor tenga la potencia para renobar la cantidad de aire que necesita tu armario. Suerte

Slowing a two speed inline fan
Can I run a fan speed controller with a dual speed inline fan? My 4” two speed fan is slightly too powerful for my grow room. I’d like to slow the fan slightly but I have heard the these types of controllers don’t work with two speed fans? Any advice or what to buy to do the job?

Best way to cool your tent/ growbox?
So I’ve built a custom growbox using an IKEA wardrobe, air vent for intake, two circulating fans, carbon extractor exhaust, and a 600W LED grow light. Temps average at 29 degree Celsius with the lights on full, is this too high? Best way to bring the temps down? Many thanks!

High RH in flower
I find it really hard to keep the RH below 50%, especially at night when temps are low. I have a dehumidifier in the room where my tent is in but even when it's below 50% there, it still is above 50% in the tent itself. Can somebody explain this? Probably help me with a solution

Cooling whilst using humidifier outside a small grow tent
I have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?

Ventilators OFF/ON
Hi, guys. I have one more question today: - My box has three ventilators. One is working in the upper air channel all the time to bring out hot air. Other two staring on my plants. Should I use all three of them? Or one is enough till my babies will grow thick to pervent mould?

Odour control
First indoor grow and is a stealth grow. I’m wondering if complete odour control is possible for one plant. One auto in the tent with a large carbon filter and appropriately size duct fan, walls are sucked in — I also have ona blocks to place around room during flower.

Additional environment control
Options for extra humidity and temperature control. Continuous drain not a problem. My Rh can stay in the 80% range for weeks. Attempting to control a 10x10. Would a small window Ac remove enough humidity (easiest)? Portable AC/Dehumidifier? Stand-alone dehumidifier? Suggestions?

Grow Tent/Room setup in the basement - dehumidifier or humidifier needed?
I’m planning a small grow setup in my basement and have a room that’s holding a steady 17–18 °C (62–64 °F) with about 55–58% relative humidity. My plan is to vent the exhaust from the grow box straight outside through an existing duct. Will I need a de- or humidifier? Thanks!
