10 days later... I've moved one the 5 gallon SIPs into the garage, left the other one outside with some top cover to keep the rain off. I moved the Bruce Banner in and left the Rugdawg (Chemdawg OG x Rugburn OG) outside, partly because my patient prefers the BB and partly because the RD was too tall! Also, the BB had shown spots of PM, the RD is toughing it out and is one of only two plants I have that have shown no signs of PM!!!! Last year my Chemdawg 91 stayed PM free through the season, that is one tough strain I will run again outside. As another side note, the Rugdawg I ran in my tent last winter foxtailed like crazy because of heat issues, this outdoor one is growing in a completely different form. It's shape is looking really good actually. I hope it pulls through, like its sister in the other 5g its losing leaves daily.
The BB has caused me to buy my first cheap little PH kit, and I tested the water today. Found out my tap water is too alkali, so I adjusted that, and I adjusted the water in the res. I'm doing a half-assed job of feeding it through the res. It's not a good set up, because unless I invest in some sort of pump to drain the water, it is not set up for changing out the res water. I did drill a 1" whole in the side of the bucket and dropped an air stone in there... for what that's worth at this late point in the game. So its getting some nutes, and PH balanced aerated water. It's also losing leaves at an alarming rate, I can't imagine there will be any left in two weeks.
The garage is running around 90ºF during the mid-afternoon into early evening, and I'm running a dehumidifier at night (can't run both at the same time, only one 20amp circuit). The dehumidifier runs warm, so the nighttime temps are around 80º. This is quite a shock for the plants three weeks away from finishing -- moving to artificial light and simultaneously into a much warmer climate (especially in terms of nights that don't cool off). I'm sure they'll adjust, but I'm not sure what the impact will be. I will keep an eye out for hermies, although there isn't enough time left in the season for seeds to mature.
The only other true SIP outside (I'm not counting the one I completely buried, even though I do add water to it regularly), is the mighty but heavily damaged GG#4. The only other plant in my yard to so far have shown no signs of PM, that tough girl is holding her own. She has shown some spots of bark rot, which is a sign of too much water. I had been top watering to try and get the top-applied dried nutes to break down and release, but I'll have to stop that and only keep the res full for the remainder of the season. Another indication that SIPs outside need to be planned around a short season.
Sorry for the long post... its been a long summer. I am still of the opinion that I won't run SIPs outside again, so far in my limited experience, nothing beats putting the plant in the ground.
