Went away for a vacation topped everything up checked timer setting etcetc, showed a family member how to top up water but didn't show them how to make sure water pump ran its course 3 times a day. They phoned on weekend saying plants aren't looking to well and that with outside air at 28c the inside of my room was hot, walked them thru cooling room but they texted back Tuesday that still not looking good I got home today to find water pump had frozen/stuck and wasn't pumping water. After a few choice words to myself for not thinking of it It looks like back to square one for this season.
