Hi Guys.
I started my first ever grow off 5 weeks ago!
I've 6 plants going (Think they're Northern Lights or Northern Lights #5 - anyone know the diff??). They're in a little white wardrobe 2'6" x 1'6" x 6'6" with a raisable shelf with 6 x 2ft fluoros (4 warm light, 2 cool white) mounted underneath it.
Temps about 76F-84F and they have a fan blowing gently on em and they're getting light 24/7 at the mo.

They're in 6in pots ats the mo and I plan to grow 'em to 12in high then force flowering for a couple of weeks to find the girls. Then transplant them to 12" pots (hopefully 2 out of the 6 being pessimistic!) and go back to Veg for a while, prune them in 2 or 3 places to get a few heads going and then wait till they're about 18" to flower em properly!

They're a bit short and wide tho' (5in high and span 9-10in!). Is this cus of fluoro lighting and not hps? Or are the light too low or high (they're about 2-3in off the tops at the mo) ??

Would like to get hps but it's impossible to buy them by cash here in liddle old england! And don't want cops knowing what I've bought with my card. Anyone got any ideas to get my babies growing a bit taller? Or are they ok? They seem fairly healthy with thick stalks and lots of foliage. Any help is very welcome !!
