i think ill give the sog a go but for that i need to take cuttings do when my plants reach veg should i go 12/12 straight away sex them then put them back to 24hrs or will this stress the plant can you sex the plant without starting budding

Ok - here goes the next stage ....

So you have got some plants and they are growing - if they are males or hermaphrodites you want to get rid of them so how do you go about sexing them...?

Well - there are a few techniques and a couple of things to remember:

1) If you are going for a rotational system, you only need one mother for each strain you are going to produce. I.e. you will take one (female) plant from your crop and use this to produce the next generation (it will be forever kept in veg under > 12hr light). So, it is worth getting this right as it's going to be your next crop

2) If you have a good eye, you can recognise females by a pair of pistils which emerge from under each leaf pair - there is a good picture here [weedfarmer.com]

3) Or... when they are about 1 foot, switch them to 12/12 and watch every day for appearance of male flowers - you risk some pollination this way.

4) If you really feel like the effort - you can cover one branch for 12/12 or less (light) and that branch will mature under that cycle. It's a real pain and not what I would recommend, any light leakage will stop flowering.

You will know when to fertilise because the plants will start to go yellow. It is worth watching this happen once so you can recognise the symptoms in later crops. Top up with any off the shelf neuts with the correct npk.

If you are using soil like StickyFingers suggested, you will probably only need to top up around month 2.

BTW: You can avoid all this hassle by buying feminized seeds - you still risk hermaphrodites but at least you don't get any males.

i tall will the sog plants get i need to decide a space to use

is it nessecery to add a small fan to the growroom because of the low temps of enviros would a fan make it too cold.

sog is an advanced technique, i reckon don't bother. you won't get good enough yields in sog without Hydroponics and hid lighting. its more worth your while to grow scrog in soil or LST. if you do still want to do sog, use disposable cups as pots in a large tray. an indica dominant strain- sog was made for these pheno's. if your gonna do 6" clones you would need to have about 3-5 per sq foot(this is assuming you have at least 50watt per square foot) with a week veg.

webguy????- since when has veg had 12 hours darkness?!?!?

what i understand from this technique correct me if im wrong is taking allot of cuttings letting them root then putting them straight under a 12/12 cycle so you get allot of small buds quickly. that sounds perfect as im an impatient cunt.

Guys, guys, what are ye talking about??

> 12 hours means greater than 12 hours!!

SOG does not require hydro - though you can do it that way if you like.

SOG basically means growing a large amount of small plants in a small area.

To maximise the light hitting the plant in this small area you develop a canopy of green by turning down the top which causes a hormonal imbalance and the plant will bush out. Less light will hit the bottom of the plant where the buds are weak anyway, more light will hit the top of the plant where the buds are better.

The indica advice is good though, they tend to be stockier and have shorter flowering cycles.

whens the erliest i can sex my plants

When they are no longer seedlings - when the leaves come out one by one instead of pairs.

spent ages yesterday writing a reply only to get logged out and have a "CODE NOT CORRECT!" message, so lost it all.

in short.

dam stoner logic! thought the '>' was a typo.

sure it doesn't have to be hydro, just personal preference.

also check out the perpetual harvest sog method(great for impatient cunts)- http://forum.grasscity.com/advanced-growing-techniques/156593-get- harvest-every-2-weeks.html

hadn't heard of turning tops down 'till recently, does it make a lot of difference?
also with sog surely you want plants to not bush out? you want as many colas as close together as possible. a forest not a field?

Turning tops down is great - think of a normal plant as a Christmas tree shape, when you turn the top down you get an upside down Christmas tree shape More of the tastier stuff closer to the light.

Made a huge difference for me, but I wasn't strictly sog - I did give them a week or two of veg depending on the strain.

By the way - well done for showing every bug in the forum in one post

ever tried it outdoor?


thank you, i aim to please

Nope - never tried that outdoor but it should work the same, I hated growing outdoors, too many things could and did go wrong!
