Spider Farmer SUPP-R30 Red LED Grow Light Bars 23.6" Long, 660nm Deep Red Supplemental Light for Indoor, Grow Tents

30 minutes before lights on 30 minutes after lights off and I'm definitely seeing the stretch and stackin' during flower phase!

Added for flowering. It helped. Happy with purchase.

Help to create the emerson effect and works just fine

They do what they're supposed to do very nicely but their power cables need some work.

Increased transition time to flower works great to add more red into my canopy.

Great supp lighting.

I live in a very cold climate and grow a lot of plants indoors year round and I was excited to get these to supplement my current lights and hopefully encourage my plants to flower and fruit better since they can't be outside at the time they are all ripening. It will be a test that I won't have the results for until the end of the year but I have high hopes. The lights themselves are very good quality, amply bright and nicely sized. Pricing is good and I'm happy with what I received.

Everything I have read seems to promote deep red diodes for stunning flower blooming. I am just a beginner with orchids and their needs. I think adding this supplemental red light bar will promote fast growth. Already seeing some success since setting this light bar up. I will try to edit this post at a later date. I'm expecting good results.
