Light has to reach the entire plant. Yes, you are correct, it is eassy now, but once they get growing, the foilage must become much more dense otherwise you get a lot of stems and sticks and not enuff buds and you just wasted a grow.

Use all the light you can. Too many people focus on just canopy light. Thats works when they are babies, but you wont get small bushes or mini-trees without ample lighting.

A good grow area needs light that reflects and bounces all over the place hitting deep into the stem of the plants. The more undergrowth, the more bud sites.

I rotate and turn my plants every few hours. I make sure each side of the plants spends plenty of time in direct light.

At least once a day, I lay my plants on their sides to address the light issue. That is one of the reasons my plants are so 'bushy', because of the presence of light!

Any part of the plant that doesnt get light, doesnt grow and flourish as it should.
