As far as I know you need the same power draw so have a 150w hps lamp or a 150w led board is actually the same comsumption, heat is kind of a problem with 400w but with 150 will be nice on my set up, it is a 2x4ft closet, usually 6 or 7 plants.
Thatās really pushing itā unless you flower them really smallā¦
Rule of thumb(usually): 150w covers UP TO a 3x3 spaceā¦ 400w up to a 5x5/6x6 space depending on the hood you use ā¦
consider CFLāS mixed with LEDāsā¦or T5āsā¦ less heat, less electricityā¦ but keep emclose as you can without burning your tops!!

Yep, medium size plants, 1 month vegg and 2 flowering, about 1m tall. My room is a 2*4, so 3x3 equivalent in square/ft.
If it was so plain like that!
I have a led lamp, true it is a bit of crap from aliexpress and was a bas led experience for me, It is probably 50-75w power draw and it can grow mini plants. So I use it to keep mothers from growing too fast under that crwppy light, has plenty of leds but not good.
That chart is from what brand of leds?
SO I ended up with 2 brand models for the same price, I donāt know witch to chooseā¦
Spider farmer SF1000
or
Mars Hydro TS1000 Quantum Board
What do you think? any experience with any of this products?

thatās right, bro ā¦
donāt fall for the ātrapā that many do = donāt substitute watts for watts,
be smart and try to match the same results, but with less cost *wink *
you can indeed safe energycost with the same result when switching from HPS to LED.
i am only using two thirds of the consumption as i did before with exactly the same yields.
i ran a 400w HPS (among others) and substituted it for 4x55w LED-
setup with same yield, less temps and same quality of bud

I like both lights to be honest. I think itās a matter of preference and stats of output and efficiency.
But being from Portugal myself,I must say it is a pity you donāt use the environment to your advantage bro!
With how summer is going, you would have to buy a few more jars at the Chinese shop instead of spending big on lights

Yeah, I will go with mars hydro in 2 months on the next run.
Portugal is dry like hell and in my area there arenāt streams where I can place safely any plantsā¦ and I cannot stand having few of all, some may die, some may burn, so because of location I donāt go outside.
I donāt need as much light as I am using, I am shure, the plants like the extra power but also suffer from heat.
I am going with a 150w from mars hydro, hoping to get near 200w hps results, despite what they say I am not confident ts1000 is all I will need but will give it a try, I can save some wattage on fans and some on light power.
I am doing between 6 and 8 plants in this small space 2x4 so it might cover the area well.
And I might do things like using hps in winter and led the rest of the year according to temperatures.

Another noob question, I will have a 150w led and was wondering if it would harm if I get a 150w hps by led lamp side.
An older rule of thumb is that you need 30-50 watts per square foot. A 150W lamp really isnāt going to be effective coverage in a 2x4 IMO. I run 300 watts LED in a 2x4, and 200 in my 2x2.
Adding an HPS in addition to the LED would get you to a better light coverage, but utterly defeats the purpose of lowering tempsā¦Those HID lamps are H-O-T!

That is why I am considering put 150 hps I have with 150 led boardā¦

I know because I am running a 400w hps in there right nowā¦ But 150w is way cooler than 400w.

Got it, I missed your post with current wattage.
Thereās no problem running HID next to LED; I would just be sure to rotate the plants throughout the grow, so growth is more even.

Soā¦ Any tips on a good led light between 50 and 80w?
Hey ho! Has anyone had experience with an automatic that takes a long time to bloom?
I have a pair of WW autos from Keraseeds, today itās been 70 days since germination, and they still havenāt really started to bloom. They only showed a few isolated pistillate calyxes. The other automatics that germinated together are already with buds in formation.
Photoperiod is 20/4 at the moment.
Iām thinking of changing to 16/8 and giving an extra dose of potassium (Ekosin Yoorin) in the next watering, to see if this flowering āforcesā.
If anyone has a similar experience and can share it here, it would be extremely helpful!
Fya!

Ive always run my autos 12/12 from the start 
Why i do this is because some of the phenos are slow to start. My best advise is to switch to 12/12 and your widows will go into full flower.
