I bought 2 full spec high lumens spot lights to prove to someone that with these 2 $25 dollar lights i could at least grow a small auto dwarf, you can buy clamps for the spots for 10 bucks that is what i use for sidelight, anyway this is final results.

That's pretty cool for cheap lights! Do you recall the harvest weight?

That's really impressive!

I've got a couple of 4ft LED shop lights I scored for $3.99 ea going to adapt them into my grow box and probably throw in an additional chandelier and a mix of 3000k and 5000k globes

Would be really interesting if there were a way to compare this approach vs. $80 Amazon light. If you get really bored in the future maybe you can do it again and compare? HAHA!!

Lumens are the key to the small bulbs. That and popping off the domes.
Click to expand...

Popping the domes makes a massive difference, although I cracked a LED on a couple of the globes haha so they're running at 50% until I can solder the break.

Dried weight??? I get what you're doing....but at this efficiency, you may as well shop at a dispensary 2-3 months for 7-14 grams sound right???

Nice, how you find them ?

I'm thinking I'm going to chuck in any cheap ass LED I find and see what I can grow, this is a prototype test bed for a future dedicated grow room

These are in walmart, in my store theyre just past the normal bulbs toward the end of isle theres fluorescents and led light bars, one of those bars happens to be a blurple 12w, for i think it was $13. They grew my current 5 plants into early veg before putting in 6x 40w t12 tubes instead, until just this week i got my new viparspectra light so those cheaper ones are strictly used for seedling babies now but could probably grow 1-2 small autos sidebyside underneath if i kept them like 4" away lol (which i might try with a seed or two when my order comes )

All running now.

In the process of breaking the domes I knocked a single LED chip which killed half the LEDs.

Nothing a dollop of solder won’t fix

so the setup is

7 x 3000k 15W
7 x 5000k 15W

Pack of 4 of ea was $2.99

Quick update, being super busy on real life projects, but I grabbed another cheapo light fitting, need to grab some more $1 globes just threw in the scrappy ones I had left.

The box has become the defacto home for seedlings that couldn't be planted outside due to the weather, they all seem to be loving the light.
