Lighting Яaspberry Cough fem (photo), DWC, 0.12m2, GN HS1+DIY 77W

Damn do i love to watch this HS1 is about 40cm from tip of the plant and you could see, how plant is not stretching, but getting more bushy because of amount of light it gets. Strain description says, that it is tall Sativa dominant with 1 main cola and not bushy, but seems that intensity of light is capable of make plant rethink it's priorities despite genetics Can't wait to see what's next :smoking:

Guys, i am really happy, that all this is interesting to you So take your popcorn and watch this show together with me I myself do not know what will be next, so let's wait and see

Looks great marimar
Are you using the 60x60 or the 80x80 diffuser with your LED?

 

[HolyTHC]

It is standard 80x80. To be honest, best optics i ever seen. You can keep plant up to 20cm to lighs at late flower, and buds goes crazy like this and dense as a rock

I have seen this only under HPS 400+. 60x60 is great thing for sure, but i do not think this is the key thing. Most important, that diffuser is making light somewhat pleasant and very friendly to plants, like soft or smth. That is really unique.

13 day from helmet

Today topping was planned. After close inspection of the plant i decided to give a try another method - i will not top this plant at all, till it reaches height limit. I think that light intensity will not let this sativa to stretch much, already now i can see that internodes are ultra short, so i'll try to grow similar bush as i did with auto, just stretching side branches alot and stunning all growth with intense light. Removed two leaves from central cola. This will make central cola to grow even slower and this way side nodes gets more lights.
Still under HS1 alone, ~40cm from plant

Wow! This is really interesting move you did and looking at the excellent pictures of the procedure I cannot wait to see how it works say a week from now! This is so awesome!

I am so going to refer to this when I am going to grow some tall sativa bitch again. I started to think that I stay with indicas just because they are easier to control.


Looks super nice healthy green and picture perfect!

Most interesting part will be in preflower, with all that stretching thing But there are another 77W of Lumileds, these will stop all stretching for sure. I would say there is minimum HPS 400 in that box now, this is crazy Will use same lights in bigger box soon, but for now this is some kind of light oven A good chance to learn how super intense lights works on plant.
And there is one thing, i'd say it's most important - you can always put lights a bit away and let that plant stretch

Yeah Marimar thats a hash tip at the top of that bud. A good sign the LED was too close to the plant as it does something to the Chlorophyll. Im thinking if you are using the 60x60 diffuser because the beam of light is narrower the light concentration will be better making better light perpetration and thus slightly giving you a better bud quality and yield over all.
Thats just my thoughts, its something im going to try out.

 

[HolyTHC]

I think that it's not in beam angles and LED could be used totally without optics easily (they have 120' optics by default). Most important thing is light spreading. For example 2*HS1 is way better than 1*150W lighs, because it (2*HS1) may be used to give light from different angles, like sun is doing in nature. So IMHO it is best to split all lights evenly, using ~200W of LED in 1m2, when using Philips Lumiled, and keep lighs close to the plants, like 20cm in flower. That are just my thoughts too, but that idea works well with CFLs too, it is logical and may be pretty real

 

[Grim Reefer]

Thats an interesting idea. I will keep this in mind while using the LED. Its something i will have to test out.
Something i would like is some side lighting. Do you think i could rig something up using the Philips lumileds?
The side lighting panels would get pretty close to the plant.

OMG man sure you do Just buy big heatsinks (bigger-better, ridiculously big - the best ) and some lumiled based matrix, or lumileds on stars and you will have perfect side lighting. HS1 is great lights, but side lighting is also very important thing. You could use some of Osram Fluora lamps for that too. Or simply bunch of 7-12W COB whites, same bulbs as you maybe use in you house You could do whole grow with only these, just bring together up to 100W for one plant of these, these are nt so efficient as HS1/lumiled

P.S> if there is not much space - you could use Lumiled stars, mount these on aluminum base and put it on walls. All that system could be run at 20-30% of it's possibility, this way side light will be not too strong, temps will be very cool. This is what im planing to use myself later in new box.

P.P.S> i did side lighting with cheap LED strips - it worked, but heat was an issue. Lumileds on 20% of their power would be much much cooler and would give good amount of light too.
Just few aluminum strips and some hand work.

Thank you for the advice.
i will do some research on the Lumiled optics you advised.
I have no clue when it comes to technical stuff. But im sure il manage something.
