Can anyone recommend a cheap co2 meter...
DankGardeneranswered grow question 5 years ago
If u want to just monitor not control I recommend CO2Meter RAD-0301 Mini CO2 Monitor. Amazon has it for 69 dollars. If u want to control I recommend Titan Controls Preset Carbon Dioxide (CO2) Monitor & Controller, 120V - Atlas 2 for 233 on Amazon

I'm running 2 exhale standard size Co2 bags in a 2 x 4 ft tent. I'm using an Auto Pilot ($100) temp,humidity, Co2 meter inside I run from 550 ppm lights out up to about 1000+ ppm lights on with an exhaust fan running. https://www.amazon.com/Hydrofarm-Autopilot-Desktop-Monitor-Logger/dp/B01FYWU2IS/ref=pd_lpo_sbs_86_t_0/145-3135595-8031458?_encoding=UTF8&psc=1&refRID=MWK6W

Hey Guys! Iβm doing two autos - Runtz Auto by Zamnesia.
Currently entering the 3 week. They have precisely 15 days from seed.
What do you think of topping? Or half topping? Regardless, i found some different answers, positive and negative about this method of training.

Show I cut main stem?Should I get rid of the main stem and just grow the surrounding bud sites? The main stem is getting too tall compared to the other stems so thinking I have to do something to help them catch up? Or just cut the main stem entirely? Finished 1st week of 12 12 tonight.

Is periodic, light defoliation ok for autoflowers?Hi Growmies!
As a beginner, I decided to leave one plant untrained, but I am noticing some large fan leaves preventing light from reaching lower branches. Is it ok (or beneficial) to periodically remove a large fan leaf if it is blocking light? I hear autos are tricky.

Defoliation in SCRoG - Leave it or do it?Tomorrow will be day 21 of 12/12. I am of the opinion of letting the plant canabilise itself for nutes that are stored for exactly what it needs, when it needs *which it is doing on the low/no light leaves but what are other peoples opinions/experience. Canopy is as healthy as!Leaves. Dropping off

How to lollipop?Started lollipopping this week but did not remove all leaves up to the trellis because I was worried amount plant stretch and shock. Should I keep the leaves at the current level (about 2-3β below trellis), or cut it all off? Should I wait until flower or do it in veg if so?

Did I over-defoliate these? Are they looking healthy for day 22 or so of flower?This is my first grow. I know my plants have a shape problem, I didn't know about LST during veg and wasn't taking it seriously (I tried to train one but it was too late as you can see). They had a very rough veg life but now they seem happy in stable conditions. How do I look?
