you would most likely want to have it setup like Haze 420, he may be back on later..., i went straight from clone (with roots ofcourse) into the large pot.
2x 600's would be hefty for that space...ideally you want around 600 watts per 1 metre squared.
If you have 4 different strains then go for 4 pots, if they are the same strain then you could grow a couple of big ones, or whatever suits your needs really. it is easy enough to set up a recirculating system that feeds automatically. the feed rings up top get fed via a pump on a timer, the pot sits inside another pot, which drains into the bottom pot, and returns to the res tank. The pump auto feeds every 2.5 hours, 15 minute feeding times.
Im interested in the auto feeding but don't have any idea where to start with that. I will be growing the same strain, so do you suggest grow 2 in the same pot? Is this the best was in soil with a scrog? Thanks
