Thats good news. I will be upgrading my controlls in the off-season too, Digital settings will be nice; I can get along fine without being programmable/automated.
The difference between having digital and 'analog' settings for the thermostat has been like night and day for me. The STC-1000 that I got is from Elitech - about $15 in the US - the only difficulty - for Americans - being that it reads in celsuis. I am originally from NY, so I'm not too keen on celsius, either, but I pretty much got used to the 'special' temps I would need to know in this process (like 95F, not going over 104F, 120F, etc). Now if someone says to me, gee its 40C out today, I know immediately that it's 104F, without even computing...

Anyway, I HIGHLY recommend doing the thermostat digitally!
And now, for something completely different....leaf ripeness. OK, I am getting this. My first two runs consisted of green, unripe leaf. The leaves yellowed at different rates, inconsistently, and it was a difficult process for me to ascertain when to move on, etc. For this run, I took only leaves that were truly beginning to yellow on the plant. What a difference - in 36 hours, there is hardly any green left, the leaves are all pretty much at the same level of color, etc. Far easier!! I know that my 'product' from this run will be low in nicotine, mild, etc., as it was basically the first tier of leaves that I used - not the ones laying on the ground covered in mud - but the ones directly above them. All part of the learning process! I will be able to move on to wilting at 48 hours easily, and I can see how, with properly ripe leaf, whatever tinge of green is left in them will disappear during the process (in the past, much of my greenish tinge stayed there, no matter how long I held at 120F - I'm assuming its just that the leaf really wasn't ready).
My plants are still growing, and so far, no sign of budding. I don't know how long it normally takes for the plant to mature from planting out?? Most have been in the ground (transplanted) since August 4 - so only really about 6 weeks in. I hope that I don't run out of time, and am hoping that the tunnel actually gives me a longer season than I normally would have here - keeping the ground and the air inside the tunnel a bit warmer than outside. I have two plants that I grew outside, that have been out there since the beginning of July. They are flowering (heads bagged), but funnily enough the leaves on them are nowhere near as large as the ones in the tunnel - they are a bit shorter, but nowhere near as wide. And not showing any signs of yellowing, either. Another thing I have noticed is that my plants in the tunnel are different colors. I have one or two that are a fairly pale green - stems, stalk and leaf. Others are a very dark green. And others are in between. All right next to each other. While initially I might have thought that this is a fertilizer issue, as the plants are pretty close together, feeding off the same ground/nutrients, I'm not quite sure of the reason. Has anyone else had similar results??
