Sweet Seeds Dark Devil - 100w COB LED

Day 46 - yesterday

1.5ltr @ 6.5pH

2.5ml grow
4ml bloom
2ml topmax
1.5ml cal mag

I've moved the light a bit further away to allow a bit of stretch. She's only about 5" high so far. She really was tied down hard ;)

She responded to the light move, has given her a bit of a stretch.
The cob led is definitely underpowered. I got a draw meter and it's only pulling 55w.

Looking good still GMan, was the COB sold as a 100w? If it was the 55w draw is about right, my 400w draws 210w.

Grow leds are powered at around 50-60% of their max to increase lifespan of the bulbs.

I tend to use it as a rough guide when checking out different brands, if the lights are powered lower than the % above it usually means that the manufacturer has skimped on heatsinks/fans/drivers or all three.

I can't remember which company it was, I was looking at their big advert saying how great their new 5w panels were but when I checked the details they were only powered at 28% so their 500w panel was only drawing 140w so I can only presume they had chocolate heatsinks!
 
Yes, sold as 100W. I was expecting about a 60-70w draw. I'm not unhappy with them, check out my amnesia she's doing great under one of them.
 
Day 60

I've neglect this girl. I had some personal issues crop up and my water/feed schedules went out the window. In the last 10 days she's received water just to keep the pot wet.

Today I've got back on track.

1.5ltr @ 6.5ph

6ml bloom
4ml topmax
2ml cal mag
2ml seaweed
Molasses

She's not going to yield a lot, I introduced the bloom nutes early to see how it would effect the stretch. The buds are beautifully formed, getting loads of colour in them now.
