Red Light

I have 400W White Light that I Full Spectrum and so far doing good .

I know quit drooling but looking at an 800W Light that you can turn to Red for Buds.

What I'm wondering does Red make a difference. I know wattage will but will color?

Another thing is double wattage is it worth the extra $800 for it?

Regarding your color question, yes. During my prior bloom I ran 2 blurples which, while not precisely identical, are both very similar. Combined the lights had 68.7% red diodes. I had them set on 6 hours of darkness, and did not expect the plants to bloom. They started blooming.

Keep in mind mine was not a science experiment with proper controls.

Check out MedicGrow fixtures, i think they have switchable AND dimmable UV and Red bars.

My dad claims his nugs are noticeably denser on the side of the room that he added a cheapo red LED light.

I have a 36w deep red grow light (660nm) on one side of a SeaOfGreen. The group is in the 3rd week of 12/12 lighting. The plants on the side with the red bulb have buds that look like 5 weeks development and the other side is what I normally expect at 3 weeks. I have the other grow lights on, also, so the red is just extra. Still a few weeks to go for the real verdict, but I’m thinking that red light is having some kind of effect. Feeding with Tiger Bloom every 5 days or so (if dry.)

Deep Red light has shown to penetrate leaves nearly as good as green light and also promotes cell growth like crazy.

I just remembered, i have this cellphone video light & it has a red setting. I wonder if this'll do anything??

I mean. I suppose it couldn't hurt to try it?

Something is right with it.

Here is an update.
These are clones that I crammed into a mini sea of green because I had too many. Their lighting is makeshift with small grow bulbs. The miniSOG is next to my main plants, which are receiving my best lighting and direct deep red. The miniSOG clones on the side closest to the main lighting get peripheral exposure to the deep red.
Note: They also get peripheral light from the stronger full spectrum lighting.

There are 2 Blueberries and 1 CBD that get the extra light exposure. All three show accelerated development compared to the other miniSOG clones with the same strains and parent plants.
My photo examples are Blueberry sibling clones. *The one “without red“ was used as a test subject to determine sex and has 3 extra days of 12/12 lighting.
(I realize this is not scientific because of the peripheral full spectrum lighting.)
