i have 1 plant in a 1 gal dwc tub. will this be sufficient for the entire grow? i seen people put 30-50 plants into a 50 gal tub, so im just wondering if this works on a smaller scale.
That's pretty small, even for one. There is going to be some space at the top so it's really less than a gallon. I suspect that maintaining the ph will be tough as well as the ppm. That being said, I am sure it can be done. Good luck!
if you have plenty of time to keep it cool, and manage the ph it can be done during veg. it will not be large enough for a 3 foot plant to finish in. I have done small res & it's a pain.
