Ok here we go:
Tent: Darkroom 80
Light: 400w Sylvania Bulb with digital ballast and basic euro reflector (added a 200w 2700k CFL in there just cos I had it).
Fan/Filter: TT125 Fan with 127mm ducting and a 125/300 can filter (filter works 100%). Also a small oscillating fan is a must.
Pots: I used 10L standard round pots, you can fit 9 into the tent but I wouldnt recommend it, 6 is a better number...Im gonna be using 10L Airpots next round.
Nutes/Soil: So far Iv been using Biobizz AllMix soil (I will always use that soil) and Biobizz Grow and Bloom but Im gonna change to Canna Terra for the next round.
Heater: I had problems with low nighttime temperatures, so I bought a 2ft Tube Heater, it works ok considering you just plug it on and forget about it!
Get a digital min/max thermometer/hygrometer aswell, and your done!
Dont think I forgot anything there. I might get a second 400w HPS instead of the CFL aswell, my temps I think can take it
EDIT: As for seeds actually, dont take anyones advice on a specific strain, let people point you to a seed bank (
http://www.nirvanashop.com are an excellent example) and you pick a strain that suits YOU, your taking the risk so at least grow something you want to smoke.
