Bottom watering can be done as early as 3 weeks into veg. Just make sure you have plenty of the SMALL sized lava rock....red rock, not black.

And yes, bottom watering is just wonderful for these plants.

It takes a while as the rocks absorb the water then transfer to the soil. It could take as long as 2 days to fully water so the soil is dampened all the way to the top.

It is a labor of love.
