Hey there everyone just wondering how the hell we are supposed to keep our grow room temps below 30c. Its not even summer yet and in already struggling I have loads of fans etc but the best I can hope for is to match outside temps. Air con is not an option. Does it really make that much difference and is there anything I can do about it.

Hello first post ever... k80 here i have a bag of mushroom compost fertilizer, but i have been afraid to use it as i have not used fertilizers or even grew interior before. my plants had went thru stages of light green leaves back to healthy looking dark green leaves, and as they have been in the ground about 2-3 weeks now i am debating whether or not to use fertilizer, and i am not sure if the mushroom compost will affect my ph adversely or possibly even kill or damage my plants. i have tried to keep this very broad and open as i am here more for knowledge to improve my grow rather than go through an endless amount of troubleshooting that can dwindle my yields or even…

Okay so somehow I came around to getting some seedlings in miniature pots of soil, usually I just get some clones slap then in a rockwool slab and turn the lights on. My questions are, how long do I wait until transplanting them? At the moment their under a 600w with 1 node of 4 leafs and a second node JUST starting to emerge. And when I do transplant them is it okay to just cut a hole in the rockwool slab the size of the pot and put the seedling with the soil in? Other then that I have a bag of perlite, but just wondering would it be optimal to use rockwool? or will perlite do the same thing.

I'm doing my first indoor and liked the idea of 5 hours less light on the girls so jumped straight into the 12-1 system. It seems to be humming along really well but as it's my first indoor I don't know if I could have achieved quicker results with the standard 18-6. so if you could let me know if you've tried it and is it as good as 18-6 thanks Puks

Hello Stoners. I got a few new toys recently, a pH meter & a Bluelab truncheon. I've got no worries using & reading them... I have noticed that the girls are drinking heaps but not eating over the past few days. Now... We're 6-7 weeks in, flushed under a 4-5 days ago, pH is perfect, drinking 15lt a day & eating not a thing...? The girls look fine, not stressed or anything but with these new toys of mine I am a bit. Who knows they might have always done this... Anyone else had this? Grow hard, stay safe. Greenbum.

Hi guys, I have upgraded my res to a 220lt barrel but am finding that my barrel seems to be draining really fast - overnight seemingly. A friend has said that with the pressure of so much water in the barrel, after my timer has switched of it my be syphoning through my system to my plants untill the barrel is dry ?? Has anyone else had similar probs ?? If so how did you resolve it. I know I could perhaps half fill the barrel but that kinda defeats the larger res upgrade.... Thanks

Hi all, this is my first year growing in a high altitude regain. Only a month ago it was covered in snow, so I was after any advice or tips to help me cope with a short season. I have nice soil already turned over and fertilized, I have been told soil that gets snow covered for the winter can be low in PH, so if anyone can shed more light on that it would be much appreciated. Cheers

Hi All, I posted this in a different area of this forum, but not sure if it was the right area so hoping for some pointers here. I have very old seeds and they are a really good strain. This year, I am getting a very low 'sprout' rate and I fear that this might be the last year that I can grow from them. I have not yet grown a male from these seeds in the past couple of years and I assume this next run will be the same. If that's the case, I'm willing to sacrifice one female this year and turn it into a hermie so that I can get a good pile of seeds for the future. I see some things on the internet about 'light shock' and 'physical shock' cause females to become her…
