    First grow - GRAPEFRUIT

    250 HPS in a cupboard. 3 fem. grapefruit and 1 hindu kush ( prob. male )

    I've been trying to scoure the net for any info. about gf. The one I have is a 75% c99 cross with a 'fruity' sativa. My plan is to harvest a little early as to maintain this plants original head high character.

    For Veg: Starting 24hrs for a week then reducing to /18/16 each subsequent week followed by a 36hour dark period prior to flowering

    Flowering: 12/12 for ~2months

    I'm planning on transplanting from plastic cups with holes to a 7.5 litre. The 7.5 litre will be used all the way from veg to flower.

    So, anyone got any recommendations? Anyone tasted this before? Got any ideas about THC %?

    Hey, What exactly does the 36 hr dark period do for the plants before flowering?

    Thanks

    1st time grower here so don't flame anyone
    I've heard that this should 'prepare' the plant for flowering so as to not stress it. Also the darkness helps the roots stretch out..

    I must be on some crack. Since the posting I've been thinking 36hours is 2 days. dur. 48 hours..I think its time to de-tox and wait for my harvest!!

    No you're not going nuts, I've heard about it too. Actually I read about it on thsseeds website. Cannabis is considered a short day plant, they have a hormone that is degraded in light. So long night periods like 12/12 allows this hormone to build up to high enough levels and it triggers flowering. Supposed to get the plant flowering a bit faster, and yes, it's 36 hrs according to them folks at thsseeds (1 and a half days) but lots of people just do the 12/12 thing and that works fine too.

    I have herd those too. But i would just go with standard 18/6 and then go right to 12/12. Its proven so you won't be speculating weather it will work or not.

    OK 36 - 48hr different horses, different courses. Not really worried about this stage yet tbh.
    How about the transplant from a seedling cup to a 7.5 litre pot? Is that too much of a jump? Or should I slot a middle sized pot inbetween. I'm just worried that the 7.5 litre for my plant will seem gigantic compared to its old home
