Sorry guys, just catching up on replying to queries in this thread. Just a tick busy these days.

You can do that if you like. You don't really need to physically move the plants; you can just change the nutrient mix in each individual tank every two weeks to suit the different phase of flowering.

I move my plants from tray to tray every 2 weeks as it gives me an opportunity to clean the trays, but they really don't have to be moved. They could stay put until that particular tray is ready to be harvested.

I do find the 'production line' style makes it a little easier to keep track of what mix to put in which tank, though. I know tank #1 will always get mixed to 900-1100ppm, tank 2 will be 1300-1500ppm + whatever the PK-13-14 bumps it up to in week 3. Tank 3 gets 1300-1500ppm, no PK, and tank 4 can be simply pH adjusted tap water- but I usually don't bother with flushing in the last week as many recommend. I don't notice any difference between buds from plants which had plain water in the last week and those which just continued to get a 1300-1500ppm Flores mix up until harvest day.

Nope- the mothers need very little attention. Once I have done 3-4 passes of cuttings from a particular mother (about 2 mos worth of cuttings), I discard that mother plant and replace it with a successfully rooted new cutting. It will be ready to take cuttings from in about 2 weeks.

While my plants LOOK like they are crowded in, they really are not. Keep in mind that I trim off all branching from about the lower 1/3 of the mainstem. This gets rid of small branches and the small buds they produce. The biggest buds form on the mainstem itself. Removing all the branching also improves the airflow between the plants.

I'm a former OG poster (in fact, a former OG moderator). This op was featured in a 'sticky' OG thread for a couple of years before the site was taken down.

I could make this thread much more involved and detailed, but there's no data omitted that anyone really needs. SOG isn't at all difficult. My only innovation is putting in 4 individual trays in the flowering area. So it happens, the flowering cycle is 8 weeks and it's convenient to move the plants from tray to tray every 2 weeks as newly rooted cuttings go in and plants ready to harvest come out.

The main points that newbs need to take from this are:

a) to put newly rooted clones in to flower with NO veg time outside of being in the clone box (which runs 24/7 fluoro light). This makes the individual plants wind up being about 33-36" tall at wk 8 (they stop gaining height in wk 3-4 of 12/12 light), ideally suited for the foliar penetration ability of HPS lighting.

b) remove all branching from the lower 1/3 of the mainstem - this allows a maximum number of plants in the available space without crowding, as well as getting rid of little buds and forcing the plant to spend its energy on making the fatter ones.

umm... more than one.

Each 4x4' tray in the flowering area holds about 20-23 pots. There's about 5-8 mothers at any given moment. I usually do 30 cuttings in each batch. So, math it out! Ought to be somewhere between 85 at minimum to a maximum trayspace and clonebox cpacity of about 144 in various stages of development.

Each tray in the flowering area holds about 20-23 plants, so that's how many are coming out every 2 weeks, as an equal number of newly rooted clones are fed in to the area.

Don't waste much space on vegging. There's no need to veg any plants other than the mothers. Clones intended for flowering should definitely NOT be vegged as this will cause them to be too tall. My mums live in a roughly 1' x 5' space under a 400W HPS.

You can scale my op to any size you like. The limitation is the amount of area you have under lights. If you do crowd in too many plants for your available space (and I'm not sure what the ideal plant count for your space will be- should be something like 8-10" square lighted floor/trayspace per plant), yields will suffer and powdery mildew will become a problem. As I use 8" dia x 8" tall pots, I guess I'm giving each plant in the flowering area about an 8" circle to live in.

I have added a pic to my gallery of what the mums look like 2 weeks after doing a batch of cuts.

Just after cuts:



and again 2 weeks later when they are ready to donate another batch of cuttings:

right now i have 2 400 hps in a homemade air cooled fixture, do you think it would be better to split up the lights and put 1 400 above weeks 0-4 and put a 1000 hps above weeks 4-8 I can do this but it will be some more work or do you think it will work to just switch out the 2 400's and replace with the 1000 and be ok, I just want to do it right. Thank you all your input is just what I need!

would it possible to to a setup using dwc say in 4-14 gal rubbermaid containers, that might be more easy for me, and then maybe just move to tops of the containers every two weeks, if I dont have to split the lights up that would also be easier to, but would if I had to, just a quick thought!

was just reading in another forum it say's something like veg nutes in the first two weeks is that right because I dont want to mess things up especially that early in the game.
