    Hi,

     

    I’ve noticed from the pictures of  the course,  video and the grow kit I bought from you that you don’t fully fill the bags, they are roughly 70% full.

    Is there a reason for this? How full do you fill your bags? Should they be below the level of the filter for better air circulation?

     

    Thanks Jonny

    Hi Jonny,

    Yes, you’ve got it – with filter patch bags, it’s best to only fill around 50-60% full and below the filter patch in order to enable good air exchange.

    With larger column growing bags, there tend to be small holes all over the bag to compensate for the lack of this kind of air space.

    Best wishes,

    Adam

    If we use bags without the filter patch. should we prick little holes all over it then?

    Yes, you would need to have some form of air exchange..although you could prick a number of tiny holes around the bag it would be better to make your own filter patches to put on your bags instead as it will reduce the likelihood of contamination through the holes.

    You can do this by sourcing some Tyvek material and then cutting it into small squares and sticking it over holes you cut in the top half of your grow bags, similar to how these bags sold on ebay in the US have been made:

    The Tyvek is a breathable membrane which will also keep out contamination and is normally sourced fairly easily as it is used in lots of applications..Tyvek overalls, Tyvek Envelopes, or Tyvek sheets for roofing
