Hey man, thanks for reps! I hope all is going well with you and you are sitting back and relaxing with the fruits of this year's labour now...
One reason I won't be running the G13 auto Blueberry again is because next year I will be running several autos/photos that are blueberry crosses, plus I just think next year I am going to change things up for variation. Hardly any strains that I did this year will be done next year, just because I like to keep experimenting. There's something about trying and finding new strains that fascinates me... and what with so many strains now out there, and with with ever-increasing quality, potency, yield etc - I just can't see myself running the same stuff consistently year on year anymore, bar the odd few strains. But that's just me.
Autos will comprise the bulk of next year's work, about 75% roughly, as I prefer to dry outdoors and I find it very easy and effective to dry outdoors in boxes under a tarp during the summer, but not so much at all during autumn/fall when photoperiods would usually finish... hence why I'm going all out with autos. I'm going to get a bunch of them in the polytunnel and then have several other auto plots, each containing about 6-9 plants. I will be making a return to the cornfield as well for an auto only grow, across 2 different spots.
In regards to the growhouse humidity, yeah, that would potentially be an issue because of overnight dew from the huge temp swings between day and night. 30C days usually give way to 15C nights, still causing morning dew on everything, although this isn't always the case. And it also depends on the rainfall pattern. Last reason we had a drought from mid July through to mid September so it was very, very dry with above average temps and hardly any dew. Clocked temps as high as 36-37C several times in the shade as well during late July / early August, which would be problematic with a growhouse. The main reason for the polytunnel is to boost growth in the first 3-4 weeks, so I could easily remove the greenhouse/polytunnel cover in the last few weeks before harvest to increase airflow and prevent mould. Not to mention the July/August temps might be too high to leave on anyway. I'll just take off the cover come July and drape a sheet of chicken wire around the perimeter frame to keep animals off.
I am pretty much settled on the 5 autos I initially listed above, but I want to add another 2 to the list to bring it up to 7. I should make a poll to see haha!
