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 👊🏽🍀

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..

WateringHi guys, I would like to ask, in the seedling phase the plant does not have a big root system so I'm just giving it 80 ml per day and because it's very hot the surface dry really quick so I'm watering every day. Should I give it more to avoid watering every day?Week 1

Roots white hairinessBenefic or malefic ?
-Root affected look whiter
-We don't use any organic nutrient, but black carpet used in our last soil-coco session.
H2O2 and/or water submersion look to "kill" it, but if it's a benefic "mold", we can let them aliveWeek 6

Why should the tap root grow for some days before potting?Not a problem, but I'm eager to learn: Most tutorials recommend to let the tap root grow to about 2.5 cm before potting. Does anybody have a rationale for that? To me this sounds counter-productive (light protection for roots, correct orientation of seed). What am I missing?Week 1

Soil heaterGot a soil heater today, wrapped it around the bottom of my fabric pots. Is that the way I’m supposed to do it? There weren’t any instructions on the package & I’m not big on YouTube tutorials. Ive also been playing music for them during day light. Do any of you do this?Plant. Other
