Sweet basil is a good choice for checking whether you have enough light, basil requires 8 hours of bright light a day to really thrive (weed requires a little less), so if the basil is going okay you know you have enough light to meet the minimum requirements for weed.

Lettuce is a good plant to practice feeding nitrogen. Green lettuces will yellow when nitrogen levels drop too low (from the oldest leaves first, just like weed) and green up at a similar rate to cannabis when nutrients are added.

Both of these plants are useful to grow and can help you get used to looking after vegetation but nothing really compares to sourcing some bagseed or cheap seeds for your first run.

I really can't think of anything that is similar to flowering cannabis and the next person who says tomatoes either doesn't grow tomatoes or doesn't grow weed. There is very little that is similar between the 2 species with respect to flowering.

They do experience a couple of similar problems Mg def and spidermite infestation, the symptoms are look different, but the treatment is the same.
