    Bought some 'reusable' grow bags to create 'raised' beds in my greenhouse ..
    Marshalls Grow Beds | Four Seasons Greenhouse Gro-System

    Now as I simulating a garden raised bed, assume I do not have to fill with 100% gp compost, any suggestions as to what mix of soil / compost would be a good way to go ? , soil I'm using has moderate clay content rather than light sandy consistency.



    Thinking that 25% compost might be a good guide - but keen for advice.

    Should I also consider adding any grit sand and feed such as 'blood fish & bone' or even Growmore.

    I'd go for a mix of your soil with 25% grow bag/multipurpose mixed in. I'd incorporate a bit of growmore at the same time. Then I'd make planting pockets for each tomato plant and fill these with 100% grow bag compost. Then 'deep plant' each of your tomatoes (strip off the lower leaves and plant as deeply as you can, so the tomato produces feeding roots up the stem).

      All my tomato plants are already in growbags ... going to be using this for salad crops, maybe some chili peppers, although may leave those in 9" pots.

      Just putting these 'bags' in as floor is concrete and want to gain some more planting area.

      Oh I just assumed tomatoes Sargan. In that case for salads then your 25% compost to soil ratio will be OK. Can't see any harm in putting the peppers in there too.
