I have never grown cannabis let alone any plant before. I'm planning on using around a 2x3x5 tent with a 240w kingbrite qb off alibaba. I have already ordered a few mephisto seeds. I've done a bit of research on nutrients, but I'm still not too sure what everyone's opinion on the "best" nutrients are. It seems like there's thousands of options to choose from. I have a few questions if anyone has feedback.

1. Will the single 240w light I'm planning on purchasing suffice for a 2x3x5 tent?

2. How many plants could I realistically fit in my tent with one light, and would it be possible to add another light to increase the capacity?

3. If I use nutrients like flora grow, bloom, micro combo from general hydroponics, would I also be able to use triacontanol?

This is the link to the light I plan on purchasing. Before anyone suggests, the top of the line lights from horticulture lighting and similar sites are wayy out of my budget.
