dont beat yaself up too much dude we all gotta start somewhere!! ive had all kinds of issues with timers, ya best bet is to pick up a mechanical timer, the brand Grasslin are a safe bet and not too pricey! you also may find that using a grow light that has more of the blue spectrum for vegging works better, then switch to more red for flowering. as for space dude, make them do what you want them too! i use 2 layers of nets in tents, one relatively low to train the branches to make a canopy, the other higher up to support the buds, its all about filling that area, any light that hits the floor is a waste!! best of luck g and dont lose faith!!
