LED’s for growing weed; the jury is back in with their decision.
I’ve been growing weed a long time. I hate to admit it but my first crop grown outside was in the early 1980’s. It was pretty good but I ruined it letting the plants dry in plastic bags in a shed in the back yard. Boy what a mistake that was. Every plant became moldy, ruined about 50 plants over 6 foot tall each.
You learn a lot over the years and a few years ago I decided it was time to switch to LED lights to reduce the use of electricity; HD lights suck watts like crazy.
At first, I was head over heels in love with LED. The room is cooler, I can put more lights on one circuit and the plants grown under LED during the vegetative cycle are a little shorter and bushier than plants grown under HD lights which is perfect.
I have 3 full grows with LED and the 4th grow was using LED during the vegetative cycle and switching to HD lighting for the flowering cycle.
I don’t have a scale (never keep a scale or baggies around if its still illegal) so I really don’t weigh my yield plus I’m always running out of pot so I continually pick from the girls while they’re still growing, but I’m certain that the buds are larger using HD lights versus LED lights.
On my last grow, I used LED for the vegetative and HD for the flowering cycle and the plants all had larger buds and bigger yields, according to my eyeballs which are fairly accurate.
So I’m changing my recommendation from using LED all the time to just using them for the vegetative cycle and switch to HD lights for the flowering cycle. If you have the room and enough electrical circuits, run them both during flowering.
NOTE: one thing I should mention is I’m using fairly cheap LED lights made in China; Mars, King and a another brand I can’t remember off the top of my head. All of them are 2 years old.
Would better quality LED make a difference?
I would love to hear what you think; please leave a comment.
What’s your experience with LED’s?
UPDATE: I am now using MH, HPS, and LED during both growing cycles, veg and flowering. It’s working out so far but I’ll let you know at a later date.
