Do I need a exhaust fan?
Autogrowzstarted grow question 6y ago
Do I really need a exhaust and intake fan for a 20x35x63 grow tent? Would a exhaust fan alone work and let air passively come in from a bottom “vent”.?
Thanks!!

Depends on if you want your plant/plants to grow fast or at all. You're going to want an intake and exhaust fan unless you're growing outside. Also unless you're household and you're neighbors love the smell of weed you're going to want to invest in a carbon filter by at least weeks 4-5

If you can add a fan to increase airflow then go for, the more air circulation the better.

Hey bro! Do you have a 100mm diameter exhaust duct in your tent!? A 100mm economical 8w inline fan would be perfect for you. It pulls 100 cubic meters of air per hour! That’s enough to create super air exchange in your tent! But, I recommend connecting it through a controller dimmer! This will allow you to control its speed so the tent doesn’t get sucked in too much while it’s running!
You don’t need an intake fan! The exhaust will handle both tasks at once! Just take care of the fans blowing on the plants!!! 👆
Good luck, brother! ✊😇

Hey I have a tent 24x24x48 and I put in a 4” blow fan for the exhaust and it really made a huge difference with my temps and my humidity. I would get at least a fan for the exhaust
Happy growing

Encouraging heightI just raised my 900w led to 39". Feeding every day about .3 liter. It looks like she will have 8 main colas after the 4-way top but I'm concerned about height. Should I wait for 4 nodes on the new colas and then switch to flower maybe? Thanks for the great advice as always!

Hydroponics and tent height issuesI'm looking into hydroponics, and have been looking at the GHE waterfarm. But worried that with a pot being 37cm and my tent being 120cm, I'll run out of space. At least having to turn down my light to prevent bleaching or heat damage. Any advice on this?Week 1

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?

Help understanding PHI have big problems understanding my PH levels. I put in @5.5-5.8 PH (lowered with acetic acid) and the run-off is always too high, about 7-7.5 PH. I started testing my water / nutrients by intervals and nothing makes sense to me. Every test shows an increase in PH, up to 2.7 up?

Light came on for about 30 seconds about 3 hours into the dark cycleSo Im 3 days into 12/12 and I bumped my timer last night and my light came on suddenly during the dark cycle. I immediately shut it right back off. Was I wrong in shutting it back off right away? Should I be worried about anything?4y ago

My tent is 32"x32"x63". I've only ever done one plant at a time. This time I am attempting to share the tent with a hydroponic grow in a 5-gallon bucket. I normally grow soil in a 5-gallon smart pot. Should I use a 3-gallon instead? Last grow the 1 hydro filled the tent.Week 2
