Hi, 1000 watts HPS grower here...
I'm starting my 2nd real indoor grow. First time around I vegged 4-6-weeks and flowered 7-10 weeks. Had my own White Rhino x Dutch Treat, Vanilla Kush and still have 3 Tangerine Dreams. I've cloned them and keeping them small under t5's until the big room is vacated. These were fimmed, so I will veg them and do a regular grow.
But the next one after that, I'm seriously thinking of going 12/12 from seeds. I have 2 VK fem seeds and 2 TD fem seeds that I will try... Have anyone try these under 12/12?
I'm also going to get some other seeds and need suggestions... I see Orange Bud does well, I like sativa/indica hybrids, but I like them a bit more potent!
Currently I'm using soil less mix and Advanced Nutes, but thinking of switching to something cheaper and more simple lyne dyna-Grow or something like that... I do not mind my AN stuff, I use Iguana Juice as base nutes so it's mainly organic, but I have to use so much other things to make sure it comes out right. I got some quality buds this time around, but only 1 oz per plant and took me 15-16 weeks total. If I can get 2 oz a plant on 12/12 from seeds, I would save time, energy cost, some nutes... it sounds perfect. I could also go perpetual under the same light in the same grow room (I have only one, so I'm keeping my clones in the computer room in the house. I don't like it much, nor does the wife)
I grew 9 plants under my 1000W hps, and I vegged a little too much so it got over crowded. I figure I can do nine 12/12 from seed without overcrowding. Ultimately, I'm aiming at having a rotation of 3 plants every 4 weeks or so... that would be perfect for my needs.
