Too small for 4

The idea was to do 4 8L pots instead off my dwc because I cant b bothered trying to battle water temps during the summer. Bought 4 single packs from seedsman and got 3 free seeds. Fast buds Wedding cheesecake. Fast buds orange sherbet. Fast buds purple lemonade. Fast buds pineapple express. Started germination on all 4. On 4th day the wedding cheesecake and purple lemonade had popped. On 6th day orange sherbet popped. I decided by this point that the pineapple might not germinate so I decided to start a lemon auto(free) as a backup. On 10th day the pineapple is a no show but the freebie has popped (4th day). Calling day 0 as the day the 1st 2 popped and managed to get all germinated except pineapple within a couple of days of each other. So aim now is to top all 4 and get the area as full as possible with training and defoliation. Bit miffed about the pineapple as that's the one I wanted the most. But nice one to seedsman for the freebie.
