What do you mean waterfarms don't recirculate?? They aren't drain to waste as the nutes drain back into the rez and then are recirculated back through the system.
i should have stated it better so what i ment was that wf dont fully recerc. like ebb and flow i run 18 currently and the gravity feed from the main res. is stagnent can be and should be modified gh makes a kit that helps its like the nute drip sys. but placed inside control unit, many things good about it , but like anything could be improved
To the OP,
If you are going from seed, I strongly advise germinating the seed in rockwool, its fairly straight forward, soak the seed for 24 hours then plant the seed into a 1 inch rockwool cube that has been premoistened. Once the seedling sprouts, plant that bad boy in your waterfarm and your off. Of course, there is alot more to it but thats the basics.
BTW, take a look at the grow log in my sig, I am running two waterfarms right now.
good luck.
