Barneys OG zkittles & Purple Punch

Barneys farm Autos for me again👍🌱 absolutely stoked with the results on my first grow. Enjoying the bud so much especially the pineapple express which once cured properly is an amazing smoke👍 I'm trying 3 Zkittles og and a Purple Punch! Last time was my first grow and as delighted as I was at ending up with 13oz of nice bud from 4 plants there was lots of errors and room for improvement. Couple of changes to the set up. I've added air domes to the bottoms of the pots, they claim to increase yields by 20% so worth a pop! this time as soon as the roots take hold I will be switching on the autopots as I have a 2 week holiday booked! Seeds were soaked for 24hrs and then popped straight into a poly cup of pure coco dampend with grow more root boost. These were then covered with cling film until they hatched. 4 days later all 4 were through and went into the tent under the shade of the last one I had finishing. Nutrients for this grow are going to be GHE Flora, Grow and Micro just for the simplicity and because I dont want any salty/silcon build ups blocking the auto pot system. I will add in terpinator too as flowering gets going. My biggest worry is leaving them for over 2 weeks. From watching others I'm thinking I'm going to need a 100ltr res and I currently have a 45!
