Lessons learned on my first indoor grow

First, here's what I did.
4x8x7 grow tent
600W HPS light 18-6 for 4 weeks, 12-12 for 6 weeks
10 plants, 4 strains, 1 gallon pots
Water every other day Mirical grow every other watering

Next I'll tell you I am satisfied with the results not sure of yeild yet (still drying)

Now what I did wrong:
I used marble chips for drainage, PH was way too high from chips and found them unnessasary
I rushed it ... I was out of weed and wanted a batch Fast: so this time I'll go at least 6 weeks in veg
I needed bigger pots: when I harvested I realized how root bound they were
I needed to top or FIM: not all flowers are the same the ones on top are so much bigger
I grew too many plants for my space I think as bushy these were 6 would be the right number
I also screwed up making clones only about 1/2 of them survived: bought some razor blades and new cloning powder

I'll start my new grow log on Monday ( have a golf tournament this weekend)
I have already got some plants 18" tall from my clone room and I have more plants then the room will support but there is still the wide outdoors I can use
