So I wanted to give a proper response to this instead of slinging insults. Check the picture again, it's 1 single plant. Grown under a cheapo white no-brand '300w' LED with a true draw of 80w. I got around an ounce from that. So yeah you're right, pretty slim pickings.
The power probably cost around ÂŁ30 the entire grow, so good return there, had a nice bit of smoke for around 3 weeks instead of buying it.
You speak as if the size of the grow reflects on my ability as a grower, but that was due to my living situation. I spent three or more years growing in the tightest spaces you can think of, even a effing cardboard box, learning how to squeeze as much out of one plant as possible, so I know a bit about plant training.
Now I've got my new place, plenty of space, sub my grow log and you'll see what I can do with a 600w HPS.
BTW that pic you posted up, very nice but although it wasn't a great pic, it seemed to show that you had failed to remove a lot of the lower, light restricted growth, which with a canopy that dense is certainly not ideal. A clearer pic could prove me wrong. Thanks for reading.
