I have two dwc buckets going that are td's and it is a little cumbersome trying to lift lid and water. I have just poured in water / nutes from above and fill up buckets. The large res with the flood table is really the way to go, it is easier and gives you a bigger storage area for water. mine is 65 gallons for the 5 plants in the table. And it really helps when it gets to this point. I'm not shitting when I say they are drinking 1+ gallons each plant per day. Many times I find myself saying, didn't i just fill this up last night? Good luck to your grow. Start a thread when you get going. I am very impressed with td for sure. I already have 7 more ready to go as soon as these are done. But I really want to reverse a plant and seed out a plant to have a good supply of seeds for future.
