Supplemental lighting

[DoubleA]

This is my 1st indoor grow…..3 clones from this summer. Using Spider farmer SE4500 LED in complete AC Infinity 2x4 tent. Are the extra red and blue supplemental light bars helpful? Are they worth $100 for two? Anyone ever used? They are in bud stage now

If using a modern full spectrum grow light, no, you do not need them. Waste of money.

So what light are you using in what size space and what voltage is your power supply?

Using standard flood lights under the canopy in flower will give you much better results at half the cost.

I've used supplemental multi-spectrum light bars for under canopy lighting and it worked very well. I'm typically an outdoor grower but on occasion do some indoor auto grows.

Bluey, do you use just regular incandescent flood lights for under the canopy? Like a regular GE 75W incandescent bulb pointing up underneath the canopy? I can see that getting pretty warm in a tent.

Hey Migguel. No incandescents, only LEDs. I haven't used under canopy yet but I did setup for it a while ago and only recently read a paper on what results they were getting from them. They can make a big difference for yields

[MiguelEnfermo]

Understood. I think I might try that this go around. THANK YOU!

[DoubleA]

Awesome…..one says yes and the other no. Lol 😂

Re read. CB didn't say that.

Here's the under canopy lights I use for autos.
They're cheap and adjustable. Seems to make
a significant increase in my yields.

I've got 20 & 80w flood lights about 4800K but the leads are short on them and I have to put longer leads on them to get the outlets up above about 3'6" high off the floor for water ingress protection. The 20w are probably way to small for the job anyway.

How are you guys approaching light distance for under canopy lighting Bluey and crucialbunny?
It guess they are not strong enough lights at the proposed power to need significant distance from plants, thoughts?

[Bluey]

They way I grow requires about 300 to 400W per plant above canopy depending on veg time and size so underneath I only require between 75 to 100W per plant. I've got flood lights of 80W and 20W and I'll just be setting the distance so it lights up that part of the canopy I need lit up. Just divide your light up accordingly to get as much coverage as you can. It's not strong so shouldn't be an issue

I would say given what you already have you do not need any additional lighting, keep in mind there is such a thing as leaf damage from too much light.
