Supplemental lighting

[Bluey]

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.

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

Re read. CB didn't say that.

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

[MiguelEnfermo]

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

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]

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.

Under canopy lighting at up to 50% of the above canopy lighting is showing substantial increases in yield, up to 50%, in controlled trials. Cheap weather resistant flood lighting works fine in this space.

I've run supplemental lighting in my first few grows both 660nm, 730nm & 405nm above the canopy and found no increase in yields over running full spectrum LEDs so I don't bother with extra UV or IR lighting any more.

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]

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.

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
