General Cultivation Q&A

Does anyone play music to their plants? just a thought http://www.guardian.co.uk/lifeandstyle/2013/apr/19/black-sabbath-radio-gardener-chris-beardshaw MD

I'm completely lost here about seed sex. So every seed has different DNA even if they came from the same plant? so if the plant is hermie, female or male will the seeds be the same as the plant they came from or its just pot luck? Is there away to identify seed sex by looking at it or another way? How can seed banks make sure that there femizised seeds are female? How do you breed plants? I'm guessing you have two plants one male and one female. So you introduce the male to the female when its flowering and the pollin will send the female to seed there babies? Which will be more dominate the female or male if that's how its done. Thanks in advance for yo…

Hi Guys, Would like to know if any of you know what this is or what i need to do to fix it. Coco grow using Canna A B nutes PH 5.6-5.8 I noticed i had an infestation of spider mites, i sprayed the plants with white oil and repeated after 4 days. 6 Days after spraying with the oil the leaves have started turning black starting from the bottom of the plant slowly working its way up. What should i do? PS. Only respond if you look at the photo and have dealt with a similar issue Its not nute burn as the leaves are black not brown black

Is there THC inside of the bud or only on trichomes on its surface?

Hey fellow stoners . What do you think is a better way to feed plants. From the top like drip fed or halo rings etc or from the bottom like flood & drain or DWC etc. I'm about to upgrade to a hydroponics system & would like some advice on the subject .

Yeah Gday I was haveing a read of one of our sponsors stock. I saw something I instantly fell in love with, and Im a Star Wars fan. Jedi Kush. Made by sprinkeling SSFV F5 pollen over a Clone only variety called Death Star. Death Star lends it genetics from the legendary Sensi Star (father), crossed with Sour Diesel. Take this higly credilble mother is then crossed with OG Kush. Why. Because its OG. The mere mention of OGK has stoners swooning like I'll fed teens at a Justin Beirber concert. So Jedi Kush just joined the MUST HAVE club,

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.
