Yeah you just gotta let nature take its course...it will flower when it needs too, just dont start to late...Ive done grows where i started in like july and the plants stayed super short and bushy...but i actually got some decent bud...but you cant be doing no winter grows in England im guessing huh? Yeah Im trying for monsters this year, thats why im veggin for so long, but id say just start your plants when the sun is generally out everyday and it aint cold that much no more for a couple months...you could have your grow done in 4 months......but like i said i dont no how weather is over there, id reccomend outdoor, i love it, and plants get huge.
