I have run the New Wave T5's from germination through harvest for two grows and am starting the 2nd week of flowering on my 3rd. I have two of the 2 ft. 4 lamp with mixed bulbs; 2 (3200k) & 2 (6500k) in each one from start to finish.
My setup is a 24 in. x 30 in. closet in hydro dwc and waterfarms so I can flower only 2-3 at a time with the size of the plants. I grow the girls from seed to plant for 8 weeks then into flower. I have some pretty big girls.
I am very pleased with the T5 results so far. I normally get 70+ grams per plant dry. Not the densest buds, but decent.
Here are some pics of the T5 setup and Dutch Dragon and Strawberry Cough grow. Most excellent smoke.
