I use an oil heater out in my shed for my vegging plants. I like it pretty good. Depends on how cold it gets and how airtight your place is. When we got that big blast a couple weeks ago, it kept it warm enuff to keep the plants alive. But I had a bit of water left over in a five gallon bucket and that water was frozen. It was RELATIVELY warmer in the shed than outside tho. And it hardly ever gets THAT cold here in Oklahoma.

This one is rated up to 750w. I run at 45% and because of the constant airflow it’s always active but never too hot for the plants.
Making the box means I don’t have to stress about the heater being IN with the plants creating a hotspot; and I get 2 tents to use it’s heat versus just one!

Good morning JP. Good morning everyone.
So glad the seed temperature male/female conversation was just repeated here. I don’t know to go find it now🤣

Same here Mike, I watered and the run off froze. I had to do some sealing up on the closet’s to keep the heat in. The floors are just decking so there’s small gaps between floorboards. It’s funny that I never have bugs in either closet when the floor is obviously a way in. Ive only had mites once and they came in on a clone a few years ago.

Okay this is in the house should work pretty well then.
Yeah @Pigeonman I have very little extra room so I may try it in the tent first, couldn’t be worse than the blower heater in it now. If I ever get 2 tents though, I am for sure copying your idea

Now, I don’t put the heater inside the tent. It is outside the tent and set at 65 degrees. I think the exhaust fan does a decent job of pulling warm air into the tent without crisping the leaves or taking up lighted floor space.

That’s the only drag is the space my heaters take up, I could do another one in the flower closet without the heater, or two without the tower fan.

Ya know, with my setup being rather expansive, I sometimes forget there are other folks that want to grow (and do) in limited space conditions. For whatever reason, security, etc. That makes for troubles in something like temp control. To overcome the problems ran into, people can get rather ingenious with their solutions, and I applaud every effort that works in overcoming the problems/pitfalls of ‘stealth’ growing!
I’ve never rented anywhere, always owned. Whenever we got a new place, I’d either build a shed large enough to house a couple grow rooms for veg & flower, Or convert a couple regular rooms in the place for growing. I moved from outdoor growing to indoors when the wife was pregnant with out first son, in the winter of 84, and never looked back lol
The first order of ‘business’ was always to line the walls and ceiling with the double Mylar infra-red blocking space blanket

My 4x4 is in a 6x10 cheap metal shed. I used 1 1/2" hard insulation. I heat the shed. My dehum is outside the tent too. Works pretty good for me keeping minimal temp and humidity swings.

I mean if you start out with enough even shrunken life’s good

Plant is male female within 5 days of breaking ground, no way to change it. I was shocked too when i found this out, i use to do all manner of things to sway M/F count. I now realize it was all bro science. Coty’s can be pulled and plant sex is already determined. Just fact, . NOT trying to start anything just reading the htread and saw you say something about swaying the ratio.

I have always heard that Warmer temps fool the seeds into thinking it is prime pollination season and they need to hurry up and produce the pollen to make seeds, so that tends to produce higher male ratios. Cold makes the seeds think they are in winter and have a long growing season ahead of them and produces higher female ratios. IDK if its bro science, but when my temps are in the 60’s I do feel that I get higher ratios of females.

Maybe i said it wrong…and maybe he is correct. What i meant to say is there is no swaying the ratio once they have sprouted. MAYBE during germ certain conditions could influence sex??? How could you possibly test that ?

Testing would require growing large population of seeds in differing temperature ranges and observing the M/F ratios.

Everyone is entitled to believe as they will cuz. Like I’ve said, take it leave it on anything I say, or only part of it, up to you. lol
All I say is, the proof is in the pudding.

We cool man…after i wrote it i thought about it…temps, ph, humidity could affect M/F

So I have a question.
Are you saying that seeds have no sex and that environment factors determine the males and females?

Not been proved yet that i have seen . @BigMike55

BTW, these pics don’t even begin to tell you how many times my rooms have looked like this or even more packed. lol Try literally thousands of plants, and decades of em.

No, I’m saying that marijuana seeds have both female and male simultaneously. They’ll be what they will, but you can help tip the odds in your favor.
edit…Seeds have both sex chromosomes, as they grow the stronger will become dominant. By the 6 week usually, the sex is locked in. Some strains will be longer to determine, some shorter.
There’s a lot of interesting reading on the subject, if anyone is interested. Just search online, to find a LOT of articles…Maybe you’ll take the word of diploma bearing experts? Especially on the subject of how the environment can help determine the sex outcome of marijuana seeds.
