General Cultivation Q&A

I have 6 plants growing guerilla in the bush that are about a month old but not that tall. most likely 10" give or take. The problem is I have rain forecast this next coming week. I know they're in veg and obviously rain is good....but from your experience (other outdoor growers) what is going to happen with a forecast like this on my youngins? Roughly there will be 5-10mm Friday then 20-40mm Saturday , then less than 5mm sunday, then back to 10-20mm Monday and then 5-10mm Tuesday. After that i hope for gods sake it is sunny for a while. They're getting good sun at the moment and have been since they were transplanted to their new home, I don't suspect these rain…

I live in victoria and would like some suggestions on a cheap and readily availible growing mediums.

We have all heard our friends "fishing" stories on how they grew a mommoth bud, like 2 ltr coke bottle think and 3 ft long , and this year I wanted to see if I could produce a massive effort.. so I collected some strains from mates and around the place and came up with 3 strains 1. White rhino 2. Red devil and 3. The Fruits (this one is tasty , mainly sativa ) all produce big buds (so far) and all are worth smoking , so I got the goods ready clone them veg them then put them out side with the smallest being about 2 ft tall and biggest being 4 ft tall ....and bang went to head straight away, thought I hardend them off proply but apperantly not ...(thanks chronmasta f…

I recently purchased an expensive quality (supposedly) PH stick. PH2 ecotester by EUTECH (OAKTON). I have the problem of it climbing in ph rapidly from 7 to 10 in minutes. I tryed to recalibrate it and it was so high it callibrated ph 7 buffer (new lab grade) as ph 10. Is this a regular problem and if so how do people get a regular and accurate reading ie 5.8 as opposed to 5.5 etc?? any help would be great thanks guys..

Hey guys, I've got a lady indoors under a 400w HPS, roughly at 3rd or 4th week of flower (not exactly sure), but basically want it to be finished by christmas, because i am moving out of my apartment at the end of december and so will need time to get the carpets done etc, after which time I will be relocating interstate. It looks possibly sativa dom and is currently in a 20litre pot with a soil/coco/perlite mix, (each roughly 1/3), and im just using a simple flairform 1 part flowering nute, with some bud steroid until week 5, then pk 13/14 week 6 then flush. What I was wondering was, if i change the light from 12on 12off to 10on 14off, will the plant finish sooner withou…

G'day all, Been out of the game for a cpl years now however have started using my beloved equipment and tools again which had been neglected under the house for too long! So I have heaps of left over nutes and additives from the last op and am a little scared of using it all again... I've been using with no ill effects the remaining grow/flower A&B (all were nearly full bottles heh) so no problem there, however i'm worried about using the additives. I've got half a bottle of Microbial (root zone preventative) and ozi tonic/monsta bud aswell however I won't use them until I get some more opinions on 'how old is too old' for this sorta stuff? Or should I just g…

I have recently collected some viable pollen from good strain and wish to pollinate only a couple of branches on my girls i was going to put 1/4 teaspoon of pollen in a couple of paper bags select some branches bag em and shake em leave overnite and carefully remove them hoping to only pollinate said branches. Will this effect overall yield of plant? 30 days at least for viable seeds? I realise some residual pollinating might occur i have clones ready to go but wish to have some seed as i will be using different strain next run and really want to keep this strain going with "fresh seed" any opinions or experience appreciated cheers TD

Hey crew So I got some sweet life cycle assessment software for uni and instead of studying for my LCA exam I used the software to do a crude LCA of the environmental impacts of growing indoors. The result was quite shocking The LCA was based on the following: 400 Watts of HID lighting 100 Watts of peripherals (centrifugal fan, PC fan for air circulation, air pump and water pump) 18/6 for 4 weeks 12/12 for 8 weeks Standard electricity (ie no green power or solar PV) 13 ounce yield. The outcome of it was, that to produce 13 ounces would generate approximately 725 kilograms of CO2 equivalent, or 56kg per ounce That is a huge amount considering that it does no…
