Heating outdoor greenhouse potential issues?
EmeraldLakeCannabisstarted grow question 3 years ago
I've added a heater to my outdoor greenhouse as it's getting extremely cold at night now and they're not far enough along to harvest. Could you imagine any problems occurring with this other than the obvious condensation on the walls and roof of the greenhouse?

What type of heater? A small/heater fan from wallmart works in our greenhouse 8’x16’. Getting the air to lightly circulate the “inversion layer”helps prevent any cold pockets. Don’t point it directly at your plants. Start on low. Most have a safety switch in case of tip over. I haven’t had any issues in the last couple seasons and would not be able to grow in winter without it. Good luck

temperature below ~18c is going to cause nutrient uptake issue in plant. roots? chemistry in plant? i don'tknow the details of causality, but it will turn leaves fall colors and reduce photosynthesis etc.. other nutrient deficiency symptoms in leaves etc etc...
so, i'd say the heater is a great idea... if propane, it'll be a nice boost to co2 during the light hours too. may also want to get co2/co detectors? depending on how you are heating it.
condensaton is quite normal for a greenhouse, so just make sure you don't incubate a bunch of microbes and you'll be fine.. i.e. cleaning it occasionally should avoid any problems.

Why is my plant growing extremely slowly?This is my first Propperty grow and the photo is after almost 4 weeks of growth, I’ve been giving nutes in reasonable doses and the first 2 and a half weeks was mostly cloudy and rainy but since then it’s been sunny, did the cloudy start affect it that much? And what should I do?

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?

Cat piss? Not the strain....So I've been having these brown spots, thinking bugs or aphids or.... but I spotted a neighborhood cat around our yard today, marking its territory elsewhere on the yard. Could this be cat piss sprayed on the leaves?? I wouldn't put it past this fella.... but not sure. Thoughts?

Best greenhouseHi! I'm buying a greenhouse for my ladies, I currently have these 2 options. The first fits more plants, but not very stealthy and will probably draw attention. The second blurs the content a little, but is made of diffuse plastic (can it lower yield?).Which one would you choose?
