Right, a lot depends on light positioning, you need an even spread with enough intensity to prevent stretching, which also seems to occur more under lights with lower K temperature.

yeah the pic with the leaves pointing up, is heavy stress

Not always depends how leaves develop.That pic was taken in the morning after 6 hour of dark,i'm not very sure is stress but it's possible.

Yes it is heavy stress.

I replaced my Philips 11W (2700K) for 6x not so known german brand 15W 5000K @ 8€ until I receive the E27 multipliers to rise light intensity a bit (only 6 sockets right now, went from 66W to 90W).

Here in EU a good price for Philips corepro 60 11-13W line is around 4-5€ each, the colder, the more expensive usually.

vs a Philips:

Quality wise the philips win, no doubt about it. German bulb don't look bad, but LED and PCB quality differences are obvious IMO.

Don't know how this SILs will turn out, but for starters these as they have 2x the LED chip count of the philips, should have lower wattage chips and hence less light penetration even being a higher wattage bulb.

That's the point I tried to make some posts ago, it's not the overall watagge of the bulb what dictates how hard a SIL will hit the canopy, the LED chip number counts too.

They look like great SILs for a veg tent, let's see how they turn out.

What I have noticed today while watering is a noticeable difference in stem thickness vs the previous HPS run.

Before

After

I didn't compensate light temp in white balance to show real life color.

One thing is for sure, they feel twice as powerful in terms of light intensity!

Hi guys now the plant is growing with one bulb but the leaves still pointing up.Yesterday before follow your advice i was sure it was a normal plant light response in some cases,but now?i increased a bit the distance from light and now is 15cm.This morning the plant appeared normal(first pic),the second is now.

Thanks guys sorry for the inconvenience.

IndiGio · 03-14-2018, 05:29 AM

DON'T WORRY GUYS i solved the enigma.I've simply added a second bulb as you can see in the pic and the leaves rapidly came back into normal position.
