General Cultivation Q&A

Been doin more trawling than tiawanese fishing boat Cant seem to find a post on re-using coco without conflicting arguments. Using canna terra pro with 30% perlite and 20% worm castings. Have any u guys tried reusing coco after pulling plants and whether using cannazyme or similar is a must. Iv'e read e/thing from just pulling out old root mass and whacking new seedling straight in, to multiple flushes with expensive root disintergrating, microbe chasing shit straight outta x-files. Some guys swear their plants are greener and buds are bigger when they reuse medium. Others say give yourself 5 uppercuts if u even think about it. Pathegen and pissed off microbes make it eas…

Hey guys, 2x2x4 foot grow tent with 2xMars 300 led. Single negative pressure 4 inch 100cfm exhaust fan Temps are great 22-27c depending on time of day. Humidity is ok with no plants however as soon as I place my seedlings into the grow room humidity pushes into the high 80's low 90's. According to BOM my area is 15c and 84 percent humidity right now at 8@night. My understanding is that I need to achieve 40 -70 humidity for veg and 40 - 50 for flower. I don't consider a dehumidifier a realistic option because of the size of space. How can I beat this high humidity? The only thing I can think of is another 4 inch 100cfm intake fan. Any help at all appreciated…

Do i have to have exhaust fan or is a small fan inside grow tent enough. The exhaust fan i got is fairly loud Sent from my SM-G900I using Tapatalk

After one sided debate with first time grower ever ,he was drunk after the fight ,I've decided to try and get a few more opinions on when they trim why they trim and what outcome you expect from your trimming also what effects you get after trimming so I will go first remembering all theories will be appreciated and probably no one is right or wrong basically we are all trying to achieve the same thing , Personally I never knew about supercropping etc until I got into indoors and learnt how to use google my number 1 aim is to get good quality smoko and maximise the harvest have always gone by the thought more stress more thc but certainly not to point of stressing so no g…

Has anyone tried these new Australian AutoPots? i know the old green model autopot are shit but it seems the guys who make the UK autopots have nailed it, now there is a new Aussie made autopot below https://www.eppinghydroponics.com.au/auto-pot-12-300mm-single-module-hydro-tray.html

Hi Folks, Just wondering whether anyone has had any experience with the Hailea water chillers, specifically the HC-150A. Temps are about to rise here and am a bit concerned that i am not going to be able to keep the res temps down enough to finish this little grow off. What i am hoping you can tell me is just how much of a temp drop one of these chillers can accomplish. My res is about 150 liters and I can pick one up for $100 so will grab it it is going to help. Cheers Z

I'm wondering about the nature of S1 "selfed" seeds! or rather, the variation or stability they'll grow into. I'm assuming S1's don't result in identical-to-the-mother offspring, as nice as that might be, but rather something more along the lines of F2's? In particular, my friend fighting cancer who's CBD-hunting got some Thunderstruck by Sin City Seeds, which are S1's of the ACDC chemotype (24:1 CBD:THC) found in the Cannatonic strain by Resin Seeds, which seems to be the base for most high-CBD strains at the moment. Cannatonic's webpage basically states: 50% will grow into 1:1 CBD:THC 25% will grow into high CBD/low THC (but not always ACDC tho im not too sure how c…

Will humidity at 25 to 35% slow my plant grow drastically? I'm doing everything down to the t except awaiting on a humidifer and plants seem like they need one? Also I'm in my second week of vegging from nice size clones that had a good root system.

Started making myself a Dutch bucket system pretty happy so far just need a pump. Got new light coming this week these definitely aren't up to the job Sent from my SM-G900I using Tapatalk

has anyone made their own buffering solution before to help keep hydro pH level stable for longer? couldn't find any threads here about it, or not with the word buffer in the title anyway, and would love to hear other peoples thoughts about making and applying such a solution I've been reading about them for the past few hours but it was only when I came across a comment in the following thread that an easy-to-follow recipe became apparent and within reach of regular joe me (chemistry isn't in my toolbelt): https://www.researchgate.net/post/How_can_I_prepare_a_potassium_phosphate_buffer_005M_and_pH_6 It's a long thread but here is the specific comment that caught my in…
