Big Shout out @percysgrowroom an fellow subscribers!! just wanted to hear people’s thoughts on what they like best and why? Much love ????
Not an easy subject to cover tbf 😉
Depends on your situation, but for me, HPS is king for flowering. Quantum board are awesome but too expensive. HPS is cheap and easy, you have to know more about how light works if you want to grow LED

Nice one mate, I’ve always done hps veg/flower just wanted to know how many agree lol ????
Well, Metal Halide is better for veg, as it has the blue light spectrum the plants prefer, the switch to HPS when flowers start forming. Or you can use dual spectrums the whole way.

100% led for me.
I run low watts for veg. Around 90w in a 80x80x160 tent.
450w in my main tent 1.2x1.2x1.8
I use 3500k cobs and grow autos 90% of the time.
All my cobs can be dimmed down to 10% and I love the flexibility
Using some more single cobs at 60w each if I ever need to add more.
My main reason was heat,electric cost and coverage.
I find it much easier to grow with multiple lights than a big fuck off bulb.
Nice one mate bet you grow some lovely stuff! I’m liking the cobs ??
Don't get me wrong, I use HPS, CMH and LED lights, Its just them good LEDs cost a lot of money on the initial set up. I wanna build my own QB, but waiting for Ivan to write a guide 😉
I think, QBs will rule one day, but HPS is just well known and reliable. You know you're gonna get good flowers with it.

I'm yet to try some qb's and tbh I dont really see any benefit over the cobs.
Only reason I think I'd change now was if I was having height issues. Qb's seem to be great if have a small space.
Qbs can also run a bit cooler than cobs but being in the uk I need more heat from my lights during the colder months or I have to add heating which defeats the object of keeping leccy costs down.
In my 1.2 tent I run 8 autos under 450w and get a minimum of 1.2 gpw
I think the lowest I've had is around 2oz per plant but I have hit around 1.7 gpw and they average out at around 2.5/3 oz per plant.
My very first grow I used 2x 400w hps and they just didnt have the spread I wanted so swapped them for cobs and dont think I'll ever go back.
Before I purchased the cobs I priced up moving over to cmh but with all the parts needed and the new bulbs etc every 12-18 months the cobs were much more cost effective and I took 300w of light away 
im yet to try either man lol. I've not done cobs or QBS, either one looks good.

Yep, IMO, the best LEDs are better than the best HIDs, but the best HIDs cost WAY less than the best LEDs, initially... so it's a cost/benefit thing I think...depending on your situation. I've run mid-grade versions of both... flower from my LED seemed a bit denser/tighter/more fragrant, but the HPS plants were bigger and more yieldy.... so I dunno. LoL. Hard question... replacing bulbs does suck though... ?
