Get those lights a tad closer. The nice thing about floros, is that you can get about an inch away from the top of the plant without burning.

If you don't have a fan blowing on them, get one. That will strengthen the stem for the incoming weight, and keep things cooler.

Also, by the looks of it, it looks as though it is a soil grow, so I'm curious why you're calling it hydro?

Hydro is the method of how the cannabis was grown. It uses no soil and uses just water and nutes.

Hydro, or "dro", means nothing more than a soiless growe. Looks good though! :thumbsup:
