"Do you just make up names for them?"
I haven't got that inventive yet, when I'm germing the seeds I label the mother and clones: GTM1 (Greenthumb Mix 1), GTM2 or PM1, etc. I keep a clone of every plant and chuck the males after sexing the mother - I've got 5 mothers of unknown strains flowering now, if any of them are good enough to keep I'll have to get some name other than the codes.
"Do you find you have trouble growing multiple strains? Is it for someone with more experience to mix strains? or do they use the same neuts and strengths?"
I haven't found it too hard, though I'm definitely not getting everything the plant would give to a one or two strain dedicated grower. I'm looking for strains to treat depression, bi polar disorder and arthritis so I'm going through a few strains looking for the right mix of 3 or 4 strains I'll keep mothers for.
I've got Blueberry, Strawberry Cough, Skunkberry, Big Laughing, an unknown strain from Dr Greenthumb and 4 plants from Peakbc that I think will be 3 plants of 1 strain and 1 plant of a second strain, and one last run of 1 clone each of Northern Lights, AK and an unknown strain from a breeder I won't be using again. So I believe I have 10 strains flowering in a 4 1/2 foot x 4 1/2 foot grow area (8 x 4 cola mothers in B'Cuzz, 7 clones in aero, 5 clones in DWC - single cola).
My next order is going to be to Pick n Mix for: Kali Mist, Arjan's Haze #3, Cheese, Origional Flo, Trainwreck, White Widow, and finally Jack Flash just for the fun. All for around $120, can't beat the deal.
Different nute stregnths for each, I'm going particularly light on the BB. It's not too tough to get some decent bud but specializing in a few strains is definitely the way to learn to grow kick ass bud.
I'd definitely go with atleast 2 strains of differing highs/stones.

Crap! I can't believe I wrote all that. I must be high, let me check .... yep.
