Hi all, starting my first grow at the start of November and looking to get this http://www.getupandgrow.ie/acatalog/Starter_Kits.html ..The 600 watt hobby kit is the one ill be buying. Just wondering how many plants I should grow in here and roughly what I should be aiming for per plant(oz)... It comes with a 600 watt HPS. Should I buy one for flowering too or will this pretty much do what I need. Thanks in advance..
