The ebb and grow systems are awsome, the capp system is junk, the floats get stuck , it's not hard to make a industrial strength one with a good times and good floats, I have some pictures on my computer back home showing how to make one, you could make the buckets as large as you need, when I get back home I will also post a picture if you want of the plants I am growing under double neders now, freaking massive plants for indoors , the room is not set correctly yet as am helping another grower raise production and quality up, this is in Michigan, I have to hand it to you , you have skills,
