Not lettuce, but two little tents going with some kales. Been inconsistent with the watering, but all everything is doing ok. A flowering tobacco plant in one and I think it's some nettle in the other, rest kales.

2x 3000k qb v1s at around 60 watts in a 2x2.5ft tent. The other is a timber 2vl 3500k at around 50 watts.

Yea are you gonna show us which led spectrums work best for growing lettuce / kitchen herbs?
To Date it was Bridelux Thrive 5000K. That being said I am back on 6500K T5 at the moment :D
Not sure how I missed your reply from that far back.
Where has the led journey taken you on spectrums for greens? :peace:

Duh, you were dog piling @Stephenj37826 for the crickets on his update. Where you at with the lettuce grow brother?
I can germinate lettuce seeds reliably now, and it’s been easy to keep them in dwc - they grow like wildfire. I don’t like soil much.

I haven’t tried using green. I have tried T5 vs Bridgelux strips and the BL smokes the T5s, they work a lot better. I don’t like t5s at all anymore.

this was like - wow 5-6 years ago this thread started. Since then, I have grown a lot of lettuce and herbs and vegetables indoors. Mostly lettuce, herbs like the regular kitchen stuff, some green veggies like different types of Choi and kale. Choi is awesome to grow, easy and tastes awesome. Cherry tomatoes and flowers and cactus we’ve been growing under all these leds and we even get our cactus to flower so I dunno if that’s good but they all love those cheap ass bridgelux led strips.

we also grow micro greens, sprouts and are just starting tissue culture now. When this post originally started, Horti lighting group was one of the only good options but it’s gotten so easy now there are so many leds available.. you can build a good shelf light for a fraction of the cost and they appear in all tests to work excellent. The cheapest I got down to was around $0.70CDN/watt to build a light more efficient than the first gen quantum boards. Pretty slick.

Which spectrum Bridgelux strips have you settled on for greens?
Any photo's of mature heads of lettuce? :peace:

This is my small indoor garden. It's my first. Just a simple kratky style thing under vero 29 cobs (though i think i'll switch in a couple of boards). The plants have been in the system for ~16 days so it's early days still. I messed up the start and the tomatoes almost drowned. Rucola, different kinds of lettuce, tiny tim tomatoes, cilantro, small leafed basil and thyme. This is so much fun and I have more seeds... Next up radishes.
