Hello from Ireland, my first post here too.Well ive grown outdoors a couple of times but they were a while back and were plant and walk away kinda things.i have 2 Dutch Passion. Auto Mazar germinating using the paper towel method.I will be purchasing a 250w hps kit with ballast in 48hrs or so.. i have a minimum sized area to grow which is.. dont laugh, the underneath of a computer desk! I have a worry and it is the mazar will grow too tall, i have about 28cm in complete height to work with.. will i have to move them?? second concern is i plan on using very light soil with the pebble syuff that starts with v. Is this correct. I also have seen its best for a large pot i have a 15 litre pot. too big? I plan on 20/4 light, don't have a clue witch nutes!! All help welcome
