is the 'greenfingers led grow light 2000w full spectrum' not very good compared to others?
if you don't know the light you can google but there aren't any reviews i can find, compared to say spider farmer 4000 (or others) is it much worse or a little worse, etc? if that much worse when i can afford it someday should i buy another one and count this purchase as a loss?

Did I start LST too early?
At day 22, did I start LST too early? I feel that I may have stunted the growth a little from overheating, but didn't want to wait too long to start training. Also, would a higher-powered light cause less distance between the nodes, and therefore make LST harder/less effective?

How to make stronger smell and flavour in DWC grows?
Hi guys. Just harvested my second ever harvest, and 2nd time with DWC. Using HPS, then CMH for last 2 weeks I'm really happy with buds, but the smell is a little less intense that I would like. I have used Cannaboost, which is supposed to increase flavour but I want more! :)

Grams/watt
I notice that the grams/watt calculation might be misleading. For example my 2500w light puts out actual 530watts. Should this not be the way its actually calculated or am I the only one who thinks so?

How much light - PPFD - without CO2?
How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.

Grow lights
Does this look ok? I have 2 plants not growing as fast as my macchiato plant. The other two are different strains, Runtz & Zittles. I don’t want to over do it but I know light is key so I thought I’d ask. Both 1000 watt uv & the other is led. I’m on veg week 5 of all 3.
