I used a heat mat on my 120x120 but i wouldnt use it on a bigger one. it also depends on ho much electricity u can consume.if im not wrong mine is 150w.
Another thing that i noticed,in my growing room,there a lor of humidity coming from the bottom of the structure since is not isolated.
To make it short,if you have the same problem you can put some isolation under your tent, eps up to 10cm and you are good.
in my small tent,i have a small heat mat for the night,barely i reach 20C°.
I did not place it directly under the pot,but under the surface of the tent.
Maybe for big situations is better a fan that produces hot air 🤷♂️
Good luck 👊🏽🍀

If you have a few barriers in place I'd say safe... like thick cardboard layers or towels to defuse the heat so its not so direct.
but other question is why use one, for how long and what kinda temps are you protecting it from and where is it?
Other options might be Styrofoam box to insulate the root base, cover it with a old towel if its expose to wind.

It should be about the same temps give or take as tent/room air, no? Unless it’s on the ground of a basement or something. As long as that mats not pushing above 75 on the roots I’d think it’d be totally fine..

Planting directly into soil with full of other roots? (Outdoor Guerilla Autoflower)The site is full of brambles with dense rootzones. I have dug a hole but its full of roots. Is it OK if I cut down every single root from my hole? Could my plant catch bacteria and etc from the brambles roots? Won't the brambles roots suck away all my nutrient from my plant?

FlushingShould flushing have any runoff? Also how will they react when I flush and the pH has been to high? Was 7 and I put 6.1, 1.7L, got around 0.3L runoff. Also one girl isn't drinking, been 3 days and still wet whilst the others want more. Should I harvest her? Thanks

Mold between the pots and on the soil's surface, should I be worried ?So my pots are very close to one another so they can't breathe enough but my space is quite limited and in veg maybe there was not enough extraction. Now that they are in the flowering room they have a little more space but still too cramped. It's just one or 2 pots out of six

Tap root surfacedHello
I have zero experience in growing cannabis. I germinated 2 autoflowers and both popped but, one tap root grew upwards. As soon as I noticed it I reposition it as carefully and easily as possible.Being an autoflower does it even have a chance. Posted pic on diary.

Adding soil to the new roots on stemHello everyone, after the night I noticed that there are a lot of new roots trying to grow from stem. I know this is ok, but I wonder can I add some soil on top of the existing to help develop these roots? Won't it cause stem rot? I want to fill the space in my pot

Thirsty look - exposed rootsMy plant has been looking thirsty but I know it isn't a water problem. Had another look today and saw some roots were poking through the substrate as I suppose every time I water I'm displacing it! I added some more Coco today, but was wondering if it could be anything else?

Root rot? How to fix mid flowerWhat is this and how do I fix it! I am mid flower, plant is not drinking as much as usual, there are several "bleached" spots that I haven't been able to account for-- my guess is root rot despite plant otherwise seeming ok.
How do I fix this midflower with home items?

early transplanti was reading grow questions about transplanting, and it seems i may have done it too early - they just sprouted the first node when i transplanted, and theyre small. theyre showing no signs of stress. if I f'ed them up, i'd see it today right? what are the downsides?
