Uhh, i forget to ask.
What is the best distance from led to plants? I read some theread and some people have different look about it. Some say its between 15-20cm (6-8inch) other say, to keep as close as possible.

2-6" should be fine

2-6" should be fine

terpene has said he kept his really close.

blynx has had some in flower about 3 inches away in most of his grows.

brucebanner has his 6 inches away with no ill effects.

there's a certain distance where the light penetrates the canopy the for maximum efficiency. terpene and blynx (in the original posts)explain it a lot better than i can.

The box looks great!

I do agree with panicmode that there may be more light in that amount of space than you need.

That box is only 1.07 sq/ft. From what I've been seeing, I think you'd be better off running 40w or 50w in that box. Not saying 80w won't work, but I think the yield from 40w or 50w will be similar to the yield from 80w.

Thanks Blynx! fo

Now i got PCfan 120mm 12V 0.2A. If need be i can put there another one. But still, temperature does not exceed 26 degrees. Mayby this plant wrong respond to the change of light.

Before i use bigger one 180m3/h extractor fan but it is too loud, for convenience, the task is to keep it in silence.

Tomorrow courier comes with seeds. Shop have some a problem with them. It's a reason to wait so long.

Thanks Blynx for answer!

And one about light amount. Will be there some sort of "unfavorable difference" if i stay with 80w? Bill for electricity is not a problem. I look only for the health of plants.


**English is not my native languace, but i do my best. I hope everyone understand what I wanted to write;p

I used a calculator to count how many lumens i need for this area.

Min: 3030 Lumenów
middling: 4040 Lumenów
Optimal: 5050 Lumenów

now i got ~ 6400. Its "only" 25% more than calculation said. We will see, if something goes wrong, then i will remove 2or 3 light bulb. but whats can goes wrong?

Before i used hps 150W on 0.16m2. lamp have 18k lumens, for this area i needed ~8k. Plants grows very well.

25% more than optimal is not a bad thing, as long as you can mantain proper temperature for the plant.
 
you could have:
bleaching, turning white/pink
burns, heatstress, dried leaves/curled
dying off trichomes, they turn opaque and shrivel up, once is was testing 80+/sq slammed on the plant and it was MELTING the trichomes, it was a glue like layer over the plant, but thats the extreme side and you wont get to those stages if you keep the plant happy, i was just pushing it just to push it :D

with temperatures, which are now I think that it will not happen. I hope at least;p At any time, I can still mount the next two windmills on the 12V DC power supply.

While waiting for seedling i make some fixup with cables albo mixing fan. And by using the occasion the TNTkush is not ready yet, i use box to marjoram sprouts :biggrin:
Later I will compare flowerpot from the box, and from the window sill

Little update.
Say hello to basil and "weed for soup". I don't know how it's call in English.

Sprout almost already went out.
for the moment he straighten up.

I got only one think left to do - buy mycorrhizal fungus and wait 3-4 days to replanting to target pot.

Greeting!

All very nice. Just for reference, basil cuttings root wonderfully. I took a dozen a couple weeks ago, put them in my Walmart wick cloner and they all rooted in no time.

Thanks Gardener:)


update. Day 2 after went out of soil.

So nothing special at this moment.
Sapling went out, grows 7cm (led - leaves) from the lamp.
Parsley feels good too, but its goes a little slowly.


the only thing that worries me a little is purple stem and spots on the leaves in purple too.
