@CannaScience, you mean your electricity provider? Or is there someone else who can see your electricity bill? Obviously it might seem strange when one person has the consumption of a four-person household, but there's a lot of legal activities that involve above-average power consumption... (crypto mining, keeping exotic animals in climatised terrariums...). In my experience, there are no further questions as long as you pay the bills. And if so, you can come up with a suitable explanation. But well, I can only speak for my country (Germany). The situation may be different elsewhere.

@ShitPreacher, all good points, but individually, I found that HPS spiked the bills so much that I was afraid of others being suspicious. I guess to each his own. Current LEDs are actually good although I do agree that HPS is very very close. And, I have mentioned that they produce high intensity light, which is simply perfect for cannabis. Added more points regarding the yields. Thanks :)

You've forgotten what I think is the most important point: In my experience, it's impossible to achieve the same yields with an LED in a grow tent of around 1m² as with a 400-600W HPS. I experimented a lot with high end LEDs from renowned European manufacturers and I got good results in terms of quality, but not of quantity. The yield when using an LED providing the maximum amount of light that the plants can process in my tent (~250W) was at best around 250 to 300g. I've made various runs with different genetics and different pot sizes etc. to reach this conclusion. It's obviously a good result if you relate the weight to the wattage used, but if you aim for maximum yield, then you should use a 400W or 600W HPS to be able to harvest between 400g and 600g in an otherwise identical setup, because as far as I know there's no LED solution which can provide such yields, unless you work with CO2 fumigation maybe, which tends not to be a thing for most hobby growers though. Considering average cannabis prices to evaluate the additional yield when using HPS, the bottom line is that you're much more efficient with HPS, because higher electricity bills and occasional bulb replacement are negligible cost factors when you consider that you can harvest up to 200g more bud per run, which corresponds to a theoretical value between €1,600 and €2,000 while your electricity bill will only increase by €50 to €100 per month...

This little known and seemingly unglamorous strain is the best indica I've ever grown and smoked. Massive yield + massive couch-lock. It's been a few years since I last had it but after some disappointments with supposedly superior "Cali" genetics I will soon be going back to this tried and true classic.
