Howdy pimpified,

Why would you want to grow your plants in an aquarium ?

Doing so,will severely restrict the room needed for root growth,which will result in decreased yields and all sorts of other problems.

I think that you need to read more about grow set-ups,are you trying to restrict the size and yields of your plants on purpose ?

There are basically two ways to grow indoors,hydro and soil-less,you can choose to do a scrog grow to keep the plants small and short,or grow them out in 2-5 gallon sized pots,and keep them short by topping them and tying down if needed-if space is a concern.

I think that you need some more education on indoors growing,take some time to study and prepare,you'll be alot happier with the results.

Have a good one...Torog
