    line fan attached and exhausted out of the tent. I'm only growing 3 little ladies to start with and I've just put them in their 26l final home.

    As Rollllio said 24" is way too far away, you can get your CFL within 1-2 inches from the top of your plant, remember to keep raising the lamp or the plants will grow into it, my 300w CFL
    uses about 2-3 pence a day, great for starting your seeds, cuts, keep growing and you'll get it pal,

    Default 1st grow 600w dual spectrum. Speed auto blueberry Please help?!

    Hi there peeps I'm hoping someone can help me, I'm doing my first grow and I've started with auto flowers.

    1xSpeed auto blueberry
    1xBlack skull automatic pineapple gum
    1xpostronics super cheese express
    1xpurple cheese auto

    All feminised seeds ( all have now been germinated and potted)

    I'm using a omega 600w dual spectrum lamp and I'm struggling to get a good idea of what distance the light should be from the plants, the speed blueberry is now at 12 days old (pics on request)

    The others are 4 days old and very tiny still.

    I'm looking for any advice anyone can give me towards auto flowers and the best way to produce those sticky smelly buds

    Thanks in advance

    It's all relevant to the size of lamp your using - 20 " for a 1000 watt lamp, 18" for a 600 watt lamp but these are recommended distances I can get my 600's within 10 -12 inches but that's with proper air - flow and good ventilation - using parabolic hoods.............................

    I am running 600w hps lights, I keep them no closer than 14 inches. You may be able to go abit closer if your using cool tubes. But this time of year in England it is cold so the lights will generate heat aswel. You don't want the lights to be to far away though as they will grow tall and lanky and rather than concentrating on growing lush buds the plant is focusing on reaching for the lights. Happy growing
