9 Purple Kush under 360 watts of LED. Dunit 2nd LED Grow

**dunit** · 03-14-2011, 10:10 PM

So round 2 of my LED experience. I am an Rx Grower in Canada liscensed for 24 plants. Comments are welcome and I'll try to answer questions but life does get busy so don't take it personal if I miss some.

If you grow with other brands of LED's you are welcome as this is all about sharing information to we can be informed consumers but lets not hate on each other.

If you are selling other brands of LED's I'd appreciate it if you could buy advertising and not just keep dropping links in my threads although you are welcome to answer questions about your lights and their technical specifications.

I have nine Purple Kush under two 357 Magnums. I chose PK because they are a bushier plant that doesn't get too tall and I really feel that those sorts of genetics
will do well with LED. I chose the Magnums because I am keeping the plant numbers down and looking for penetration with slightly larger plants and the 3 watt diodes and the 60 degree lens angle should work well for that. They are made by GrowPerfect the same company that makes the ISIS series.

These plants were vegged under two ISIS 170's.
In in coco with 10% perlite
1200 ppm CO2 (propane burner)
Flora Nova nutes by GH

So this was day 1 of flower on March 9th. I am just posting late and getting caught up. I don't do the 24 hours of darkness thing before triggering so I believe it takes them 3 or 4 days to really "trigger".

Hey man, good to see you starting up another journal! Will be watching this one as well.

How long did your veg those Kushes for and is that a 3x3' tray this time around?

Any training and/or trimming planned this time?

That is a 4x4 table so the area is a bit larger which is what I was hoping for last time.

No training as they are already making good use of the space and PK shouldn't get too tall. Will definately be trimming. Lower and inner budsites will be removed to concentrate growth to the areas with good light intensity. I used to do the same under HID with good results and it certainly makes trimming way easier.

They were vegged for about 6 weeks just because that was how long I had to run them to make the flower space available. I dropped the temps in the veg area to slow the growth to drag them out this long. In future I will only be vegging for four weeks

I like this grow already. Those two 357's over the 4x4 should prove to be an awesome yield. Have close are the lights to the plants?
How often do you feed in that coco? I'm thinking about switching

Room temp is about 82F and I feed or water every second day. Those are 3 gallon pots. Lights are about 15 inches off the plants.

As for Coco, I'm not sold yet. I just cut down one crop (check my sig) and had nute issues that I thought were lockout but now think may have been calmag. I see Irishboy had issues with his coco mix and just following a thread on 420 and the guy is having nute issues with coco. I think it has potential to be an awesome product and think that the cal mag supplementation may be the answer so we will see.

I like GLH and they were a close second when I made the decision to buy the Magnums. I picked the Magnum primarily because of the 60 degree lens angle which I like vs the 90 degree. I have to run fewer, larger plants and cant do sog so going for penetration which I figure the narrower lens angle will deliver but I think they are both great lights. Would love to do a comparison, sure would be interesting

What style and medium you growing?
