General Cultivation Q&A

Hi Stoners, I have only cloned off plants before I harvest them but now find it is time to keep some mothers.........I have an old 4 ft.sorry 1200mm fluro fixture or ballast I suppose, lying around....... I was looking around some sites at some different grows and saw one with twin tubes, one purple one white it looked like rather a large grow with multiple ballasts. I was wondering if any body could offer some advice on this kind of lighting or names of the tubes. I also would like to ask if you keep the mothers going 24/7 or let them have a sleep? Thanks everyone

Gday Im a bit concered with the pH of my perlite recirc. Im getting a dirft in the pH each feed. Normally the pH wont move too much and Ill have to adjust it at the end of a 12 hr period. However, the pH shift on this grow swings from 5.5 to 7+. after each feed! Im using symbiot nutrient additive, and a citrate for the pH down. I dont know if the organisms in the solution would use the citrate?? I may try the 'other' bottle of down they sold me. and concider not using symbiot additive. Has anyone experienced this before?? Im used to the pH changing just not this much, after each feed!

Background: I have never grown cannabis before and have been practising on two auto jack47 that are 59 days old from when the seed was tossed in water. They are growing indoors BUT with natural light. I have been guessing about feeding and took a stab in the dark with some minimal training based on comments from the forums. Questions: What would be a reasonable size to expect it to be by now or alternatively what size should I be aiming for with a potted indoor plant in natural light. How do you know if/when it will flower?

Ok well as ya know had a hard time with some seeds of late but heres what i got going in flower 12 plants 6 under each light bout 5 weeks in.....buds r fatter than golf balls n falling over already but can see theres alot more time needed here. Last pic is of the G13 x NYCD i fucked up, 2 seedlings survived but not going real strong. oh yer had some troubles with the new cyco nutes weather its strain or not was abit rich to follow there program so had to drop it by half hence the clawing....will get at least 12 ounces a light or 2 each plant n thats calling it safe hope for better but always allow for worse

I went to my local hydroponic shop in January and old mate told me he was out of House & Garden coco due to them having quality control issues where it was being made. So they took it off the sri lankins or who ever make it and now make it in Holland. So now it comes in and different shapped bag and different image on the front. I had noticed in my last bag and another a few months back there was a sea shell amongst the coco, so I am not supprised there has been quality control issues. I will still continue to use H&G coco as I found it to be a bit better than the Canna. The Canna seems more ground up or finer than the H&G.

Cholo! ok so i said id put some pics up so here they are! ok so the first pic is a seed i got from the local sativa here and unfortunately turned out to be male the rest of the pics are swiss cheese and Master Kush, the small fat budding plant is swiss cheese and the larger ones are Master K.. I wasnt here for there veg stage so i just let nature and the tablets do there job until i returned, as you can see one of the swiss cheese started to re veg so once i got back here i cut her down asap maybe wasnt a smart move but iv read that she will start to lose thc if u let the plant re-veg... anyway my concern now is with the MK shes been flowering for 3 weeks now and im not …

First up a big thanks to Vostok for his post about earth boxes that originally got me thinking about this. https://cannabis.community.forums.ozstoners.com/topic/58725-hot-hot-hot-try-an-earth-box-then/ Mine aint that fancy, mainly due to remote on foot only location and difficult digging conditions. Here's how I did it: Dug a hole about 90-100cm square (shape shouldn't matter), and about 40-50 cm deep. Then dug a smaller hole in the middle about 25cm square, and deep enough to take most of a 2l coke bottle (the soil was like diggin through iron at this point). Lined bottom hole with plastic, place holey coke bottle with pvc pipe attached to top in hole, fill …

Hello all, With my next grow I am using soil and moving away from hydroponics because I don't have the time to monitor the plants as much and I would like to water every other day or more by hand instead. So I have my soil mix sorted. I am using a good quality organic potting mix called Debco Organic which has no wetting agents or slow release ferts and I'll be mixing that with Perlite, Vermiculite and some Dolomite Lime. My question is: I have quit a bit of left over Canna Classic Vega A&B and Flores A&B nutes from my hydro grows and I was wondering if I could use those in the soil grow? It would save me some cash if I could use what I already have. TIA

This might be one for the more advanced gardeners out there but I was thinking about companion planting and whether weed grows well amongst South Western Australian natives like in a Jarrah/Marri forrest area. Im guerrilla planting in Margaret River you see and i know this area is like the Nimbin of WA so there's got to be a few locals on this forum that have some advice on this. Any thoughts?
