In the small grow box , We use two 12 diods 18,2 w led lamp - three 3 diodes 4w (red/blue) and ordinary two orinary led bulbs 11w . ok after 3-6 weeks you must add new light, but its enough for veg 0.45 sq/m . There are better . IT work ok and for some clones too !

What is you soil made of? Is that straight biochar as mulch?

That full spectrum might be burning some of my plants, see below. I've been looking recently for a good blue led, any suggestions on one?

I think not all full spectrum led burning plants, whether you used a 5w led?

Light burn , Yes but a lightburn that you barely can see on leaveas but the colas shrink and tha calyx dry out and the weed get dry weight and stressed so beware of that too! Had some fine Mazar's and LSD but first the colas looked wide but the light and summer hottest 2-3 weeks then even the big nice plants turned out like that , bad taste and lower every thing ..
Led I guess every led has different distance from various 5 cm to 1 meter???
Get info and test 1 day next day 2-3 cm lower or 1 inch.... Something like that. Look at the leaves and of course the whole plant.
The bulb 12 diodes can be 10 cm from seedlings but clones they don't like it at all, so there it is much better with cfl. Or ordinary led bulb.
