    Hi
    Could anyone please tell me what humidity I need to aim for and is it for the duration of the grow,or does it have to come down (Or up)at any stage?
    Thanks

    Usually up to 70% for seedlings, 50-60 % veg and I don't like it being higher than 50% in flower

    Hi thanks
    Here’s in daylight.My HPS light is at 400w and 60cm away I’ve been just spraying them with a&b at 5ml in 10L until last night when I wet round the edge of the pots with more water of the same mix PH’ed to 6.8.
    I’ve got a fan blowing in the room but not at them directly and not got the extraction on yet but got the door open to the rest of the house for fresh air.I find if I open the window I loose humidity

    I wouldn’t worry about that it looks alright to me humidity dome could help but I wouldnt leave it on longer than a few days imo.

    Are you growing in soil or coco? if it’s coco id drop that ph down a touch if I was you. If it’s soil it’s all good at that pH.
