First time grower Q&A

Hey guys, hope everyone is doing good!
My grow is in an outside shed, is has no leaks and is pretty tight, it does get quite cold on a night but not in the tent also it is getting warm now in the current climate too. I am on day 12 of veg and I will post a photo of my setup on here.
I will not waste any more time and I’ll get straight into the questions.

what is the best way to control temperature on a night when cold & on a day when hot?

is a 18/6 cycle better than a 24/0 cycle for veg?

where is the best area to put my thermometer needle in the tent?

I am using soil with a perlite, when is the best time to start adding nutrients, and what nutrients should I be starting off with?

I will edit and update more questions as I need to, thanks for listening and thank you to anyone that answers my questions

-ROSS

temp- put in a heater if too cold (below 60) light cycle- way too many questions to ask. thermo- near plants. Nutes- again way too many questions like what are you growing? What did the seed seller say? Do you know anyone else that grows that strain?

I’m growing a strain Called “Disco Biscuits”
I’ve got a heater and when it does go a little cold I turn it on etc , but even on the lowest setting it tends to get too warm, but fluctuates between 26-33 degrees Celsius

and yes the person who supplied the cuttings is a relative but they only do the seedlings/cuttings and not full cultivations

The absolute best way to control temperature is to be mother nature. If that is not a possibility, then I use a candle for heat. It adds CO2 in an enclosed space. I do worry about humidity, so I put a few dessicant packs above the lights and change them out when they are wet. For heat, I just use a fan.

18/6 cycle is better for saving electricity. 24/0 gets just a little better results in the canopy, but roots do not grow as well. The darkness seems to help with roots.

Is it an oral thermometer or a rectal? You don't have to do it in a tent. The only difference is flavor.

Add nutes to your water when it looks like your forrest isn't doing as well. I'd start out with some nitrogen rich nutes and then potasium and phosphorus stuff when you are flowering.

I would also strongly recommend you don't put an open flame in a shed or anything that's not being attended. All it takes is a mouse or something knocking it over and your done. I'm guessing by your use of celcius you're in the EU, Britain or Canada where electricity is fairly expensive. Doing 18/6 or even 16/8 will help you keep your costs down and if you run the lights at night they will help provide additional heat. I like oil filled radiant heaters with built in thermostats as they are simple and safe and can be controlled by a grow automation system. For cooling it's pretty much down to having AC or only running during the cooler times of the year. The temp is best measured at canopy level and as far as nutrients it depends on what you have access to. There are a lot of choices in the US but I understand finding them overseas can be difficult. I like dry amendments like Dr Earth and Gaia Green as they are cheap, easy to use and effective. It also depends on what the soil has amended into it from the bag as far as when to start feeding. A good general rule of thumb is to start a low feeding strength once the cotyledon leaves start to yellow.

Here’s a pic of my setup it’s in a 1.2wx1.2lx2.0h
Running 250 hps
Green box is heater 2kw but running half on low heat and fan on a lowest setting, it’s been a cold night but woke up to 25.3c and 52% humidity. Hit a high of 31 and a low of 19c, at some point but not sure why it’s fluctuating so much, I do keep track quite regularly and check over atleast once and hour except on the night
