      Hi everyone I'm nearing the end of a grow now and I'm thinking my little grow cupboard can fit 1 in but Iv had problems with so should I germ say 4 seeds on the next run leave them in small pots and hopefully they finish earlier. Like I said my cupboard is tiny 43x43x90 or do I just go with 1 again the seeds I got are auto's

      I hadn't thought of that. You could argue about the Dr/Patient confidentiality although her Dr may think the cannabis could have negative effects and putting other road users at risk. I might hold off on telling her upfront, but depending what results of tests are I may consider it. She's been dealing with me most of my life so knows the issues and struggles i face. I could say i tried some cannabis and found it benificial at the time but not say i still use it.     Yes, I'm very protective over my car as it's taken me a long time to save for one and it's rather special to me to the point I have retractable bollards, CCTV and a tracker fitted!   Thanks to everyone's comments, given me some food for thought.

      Yea i have one of those too and it was great for my 5x5 but its too big for the 3x3 I use now.    I like tower fan hanging horizontally because it's slim and provides even air flow.
