Can these Purple seeds from GoldenSeed.co.uk be grown indoors??

I was thinking about purchasing some [FONT=Verdana, Arial, Helvetica, sans-serif]Purple Star ® Twilight ® , and [FONT=Verdana, Arial, Helvetica, sans-serif]Purple #1 ® from goldenseed.co.uk . And i wanted to know if you can grow these strains indoors and still get good Yeilds?? does anyone know info or input on these and growing them indoors??[/FONT][/FONT]

I know these seeds are recommended to grow outdoors but is it still possible to grow indoors? and get very good yields?

You might want to control hight by topping and, if you really need to, only using a metal halide (or grow cfl) for the flowering cycle, that will control the stretching. I'm gona try Bushmaster myself in a bit, that is supposed to help but who knows with these products.

Ok I have the 250 watt HPS setup...i dont have MH setup. But every 1's been tellin me my 250 HPS system is good for veg. state and flowering. but whats Bushmaser and how would you top a plant?

GrowFAQ has instructions on topping/cropping
