First Grow Question

Okay, I've got things all set up for a first indoor grow [can shoot some pics].
I posted this here, because what I need to know is this: I have LowRyder, AK-47, White Widow, White Russian, ...to name a few.
Can you grow different strains together, or is that a really bad ideal ? And if you do grow more than one strain, do you have to try to grow plants with similar growing characteristics, as far as vegging period, flowering, etc...; BTW, this will be a organic/hydro grow, so many of the plants can be totally on their own as far as consideration of nutrient needs.
Thanks.

being that it is your first grow i would grow one strain.start with the lowryder as it is the easiest

AK-47 is going to be the tallest(sativa),White Widow and White Russian are pretty medium short and obviusly the lowryder is tiny.So I'd say grow the Whites together if you want but nothing else.Especially not the lowryder and AK-47

Thanks, I realize that's a real "newbie" question that's pretty much common sense, but I honestly didn't know if others sometimes grew a few different strains together; I hardly have the space or money to set up multiple grow rooms; the one I have set up set me back some quite a few bucks. 'Would be nice though !!

You coulod grow them all at the same time>But if you did the chance of running into problems is increased.For example every strain takes a different amount of nutes...But if you keep the nute level a little low it should be fine...I keep mine low anyway just incase.3/4 dose at maximum and 1/4 for young plantlets and work your way up slow...if you see nute burn ,flush and rethink your nute dose.A PPM meder would help with this(It measures the amount of nutes in your water)
The other problem is hieght...Sativa's like AK-47 can triple in hieght during the first 3 weeks of flower.Indica's ussually double in the first 2 weeks.So one way to dealo with this is to start the sativa's considerably later to keep the hieght of all the plants relitivly the same hieght.
I'd still grow out the lowryder seperate from the rest.Otherwise your lowryders are going to grow in the shadows...not good.Plus Lowryders auto-flowers,so you'll be growing the lowryder on a 24 hrs. or 18/6 light cycle...(I suggest 18/6)all the way through to harvest.And the rest will need the seperate veg and flower times.
Good luck if you got anymore ? let me know.
