i reckon you made a good choice there, i've just finished my first grow using an aquafarm. i'd done two soil grows previous to this. growing in the aquafarm was so much easier and less time consuming than soil

.
i added a few modds to my aquafarm, i enlarged the drainage holes to just smaller than a hydroton clay ball and added more to aid drainage and root growth down to res,also added an airstone to the reservoir,and a thermometer.
you'll have to look through my threads to find my diary as i can't figure out how to link it to my signature.or just search for aquafarm white widow in diaries.
got pictures of the roots at the end,well worth a look if you've just bought one.
