temperature

So warm days and cool nights can change the color of buds to pink blue or purple coloration. 70 degree days, 50 nights. I did this my final week of flush to blue dream. Some top buds turned a little bit of dark blue, not enough to satisfy me however. I was curious if I dried them at 50 degrees...

Okay so I am currently growing in a 2*4 tent and will soon be upgrading to a 4x4 or 5x5 tent. The tent I currently have is inside the house so the temps are pretty easy to control ( when it's hot the AC kicks on lol) but the big tent must go into the garage (unheated and uninsulated) now I have...

There are always discussions going on about root rot and low/high temperatures. Some people are convinced that you have to keep the temperature of your reservoir below a certain point. For example below 20°C / 68°F. Otherwise your roots will get all messy, brown, stinky. I did some research...

Hi all New here, also new to growing, so please be gentle. I have been reading up on DWC for white a while and I'm terribly puzzled with the whole DO and temperatures. Just about any site will quote you that perfect DWC temperatures are above 16°C (62F), because plants don't really like cold...

switchable max temps at 600w are 86-90 noticing some extra fox tails. was around optimal temp on 400w. this is in 3x3 bloom tent w\ hps.

Hello there, I’ll be using an 8amp Hybrid controller for my next crop, and wanted to ask about lowest and highest fan settings. After setting my desired temperature, should I just set lowest fan speed to the lowest setting (1) and highest fan speed to the highest setting (5) or is there another...

Hello all, Does anyone have any experience with the GSE Temperature, Humidity and Negative Pressure Control? I have 2 RVK fans (in & out) and wanted to know if this gear is compatible with this type of fan. What are some positive and negative experiences you’ve had with this kit? As I’m looking...

I want to share my experience with the Netatmo Weather Monitoring System. Is it expensive? $150 you decide. For some that's chump change, for others that's groceries for a month. But for me the peace of mind it brings is more than worth it. I was looking for a way to monitor the conditions in...

Hi, someone want to buy cooltube with temperature display and thermalswitch. If the temp in duct reach 75 celcius it cut the power to the ballast. Very safe for fire. Temp display is good to adjust your airflow with speed controller. 150$C for 8"

Sup peeps, so to get down to it and without going ham into describing wtf I'm doing, my questions are these. I'm doing aero in a CLE(sealed environment). I am wondering what the corresponding amperage would be for CO2 and Temperature. I have only read two topics pertaining to this which read...

I have an indoor grow in a stealth box. The temperature range in the room is 95-60 (high-low). I have an air conditioner that pumps cold air into my box, not directly - there are two walls: One outer, one inner; air blows through outer wall at the top, then enters the box through the inner wall...

My temps got way too high. Like 38c for a really short period of time. So refigured my airflow and cooling and seems to be helping. Still gonna throw a couple of co2 bags in for good measure though. Any tips. Tricks. Suggestions are very much welcome. I also have an 80w greenhouse bar heater I'm...

I am a licensed medical grower for a legal medical state in the northeast. My Goal: To grow as much tree as possible by the end of the year. Efficiency is of equal priority (space, electricity, and time), as well as some variety of medicine. I plan on harvesting every 2 months after initial 2...

ok I am growing in my camper in the backyard.. I have the whole Grow set up in the closet.. I'm in southern Ohio so it's pretty cold temperatures right now.. I have a thermometer, It has a base that shows the temps and humidity and there's a secondary device that's meant for "outside" that...

Hello all, new member here who's just started my first indoor grow. Just really asking for a basic layout of what temperature and humidity I should be at for each stage of my grow. So what should my air and soil be at for seedling growth? Then how long do I keep it at that for? Then again with...

Hi everyone, s'all good? TL;DR Worried about probable temp. & humidity issues once I start my first grow. Live in a tropical climate So I'm fixing to start my first ever grow op in either early/mid December or early January. Today I went and got the tent, a Secret Jardin DR90, and my...

I am planning my first grow in a 3x3x6 tent, four 3-gallon pots, scrog, soil, LED 600W light, 200 CFM exhaust fan, probably clones (Tangie). The tent will be in the crawl space under my house (it is a tall space with plenty of room to walk in). It is sort of semi-indoors/semi-outdoors. It is...

Okay here's my situation. I can describe more about how I ended up here if you want, but it's not really relevant to my question. So I have 4 feminized northern lights plants that are 5 weeks old and 2 grow 'spaces'. I started out with one grow space for the 4, but realized they'd probably kill...
