I was looking for some threads about other peoples' experience with T5 lighting and couldn't find much, so I though I'd share.
Below is the product of a T5 (4 - 4 ft.) grow. 6 weeks of veg under 4-6500K "cool white" bulbs and currently under 4-3000K "warm red" bulbs. The photo was taken 18-19 days into flowering.
The strain is G13 x Diesel.
2 gallon pots (going to switch to 5 gallon in a few days).
All Fox Farm products: Ocean Forest soil (started seeds in Light Warrior); Grow Big, Big Bloom and Tiger Bloom nutes.
I keep the lights no farther than 5 in. from the tops at all times, and the lights are so cool that I never worry about or have had any problems with burning.
I've heard about diminished yield with T5s but so far everything looks good... but we'll see.
I'd really to hear from others who have grown with T5s from start to finish.
