hi just new to growing my palnts have the white spikes all over it do i revers the lights as in 10 dark 14 light then 8 dark 16 light to make it grow to full and rippen can any one help please
White spikes, meaning pistils/hairs? If so then you want 12/12 lighting schedule. Use 2700k red-spectrum lighting. And read up, basic questions like this are easily answered with a little reading around...
Make sure you get a decent magnifier or microscope, so you can check the trichome's to find out when its ready for harvest. Also be sure to read up on Drying and Curing.
Thanks for the sharing, ok the pisels are white the buds are not that big using 400hps light on 12/12 have been for 4 weeks. so leaving them on 12/12 lighting when do i reverse the lighting ? or do i need to. just started 3 northern light and they grow amazinly have about 6 leaves on them all lighting 12/7 just waiting till they reach a good height 12/18 inches ive been told before darness is needed. am i right. then will i leave them under 24./7 off light till bud grows. sorry all new to this
Just leave the 400hps at 12/12 until done. No need to switch or reverse anything involving lighting now. They will finish just fine at the 12on/12off timer setting. Keep it at least 18" from tops to maximize light and keep from bleaching out tops. Good Luck with it! Not sure what your saying about the NL plants...if in veg, they need more than 12on light or they will go right into flower....for veggin, you want 18 to 24 light on times, then switch to 12on/12off for flower, which you can do at nearly anytime you want. Not while rooting tho!... and keep in mind they will grow in height another 1/2 to 1/3 in height after switching to 12/12.
Thanks for the help nl are only 2 weeks old but looking lovely have them on 14/7 till about 18inches tall, then do i put them on 12/12 or different lighting settings
Sorry I don't post pics here, but run a search (there's a sticky on that) and I'm sure you'll find the answer. As for your light schedule, it's entirely up to you as to when you put them on 12/12....Do you want them to get big, or do you wanna keep them small? You can veg as long as you want at 18/6 or greater and they will stay in veg mode and grow until rootbound in the pot, unless you keep transplanting them into ever bigger pots, or until you decide to switch to 12/12. There is no set time, it's just how big do you want them to be when they are done. They will grow another 1/2 to 1/3 of the size they are at, when you switch to 12/12, so bear that in mind when planning finished height. There are really only 3 light stages you need to grow this stuff.... 24/0 use gentle light for the clones and seedlings until they get roots going (1-3 weeks), cfl's or floro or HID's at a distance 18/6 to 24/0 for vegging, 3 weeks until whenever, it doesn't really matter as long as it's greater than 14 on, anything in between is fine but use the most powerful lighting you have. 12/12 for flowering...some give them 24-48 hours of total darkness to force them to go into flower quickly, but you don't have to with most strains, and 12/12 will take you all the way to harvest. Again, the more light, the merrier the plants! And doesn't everybody want merry mary jane? She's my main thang....she makes me feel alright....sorry, the meds are kickin in! This is actually a simple process that can be made very complex, don't make it complex.
