I've had to move my Mars Hydro TS600 from 24 inches to closer to 30 (still within spec) as i was noticing some light stress/heat stress. These were 1-2 week old seedlings. Anyone else experiencing anything similar? Not dogging the light, it's super bright, cheap, low wattage, and the plants a responding well but seemed to be too strong for my girls at this age.
Lighting Mars TS600 causing light stress?

Seedlings don't need much light at all for the first couple weeks they're focused on building a root system.
For the first 2 weeks I'm at about 30% of my max. Or about 200w over 16 square feet.
When I used to run photos with a veg and flower room, seedlings and clones went under t5 fluorescents then moved out under MH lighting in the vegetation area. Not a lot of light at all.

Why it feels right to me to run lights softer and more blue when plants are young. (Bro-Science). When you plant a seed outdoors in the spring when the soil has warmed appropriately. The angle of the sun is greater to the south (where I live). The light is not as intense as it will get in the summer. The spectrum has more blue light then. This changes as the season progresses to stronger more red light. So that is how I run my indoor lights. Softer bluer in veg. Move to more intense red for flower. I manipulate the whole spectrum as I grow.
I run these in a 4x6x8 space.
2 - 500w Chilled Growcraft LEDs
2 Far Red Pucks
2 Royal Blue Pucks
2 50w LED w/blue
2 - 48" t5 Agromax UVA Plus 10,000K florescent lamps
1- 48" t5 Agromax Pure UV 75% UVB 25% UVA florescent lamps
Writing that just reminded me of how beautiful it is to be out early on a crisp spring morning planting some vegetable or flower. The color of the mornings then is the best of all year. Thanks for that.

I too control spectrums according to stage. Germ/seedling under T5HO 6500k...can get within a couple inches...at three weeks everything, autos and photos are moved to a flower tent under cobs/qbs/hps mix at varying distances per spectrum/age...8-20"...
Coddle and love your seedlings for 3 weeks under less intensity lighting, then you'll get the most outta your efforts.
