Mars-Hydro LED Grow Light Discussion

I think the single 400w II for that set up as its only one panel to fit in and a extremely high watt per sq ft.

But it would be more fun with 2 Panels.. one for seedings and starting the grow off and 1 for a flowering tent.

With two small grow tents you could have a Auto harvest every 6 weeks.


Thats the latest Plan I am implementing is to have two Auto's in flower and Two in grow in two tents/cabinets.

So I start them 6 weeks apart. For me I need to start my next two seeds in about 2 weeks to get the cycle starting.
 
You could double up on the micro nutrients for the next feed as it looks deficient in one or more.. Have a look at the Cannabis leaf deficiency chart thats all over the website and the Internet.


Like Denise said about checking your water/nutrients PH.


In case your not on top of your PH , Remember to do it after mixing nutrients up , its VERY important , if its off the micro nutrients become unavailable to the Plant. thats called PH lock out and very common for people who Pay little attention to their PH to have poor crops.

Your Plant is looking good , often old growth can look ratty , its not so important but is a sign .. the New growth *could* be next.

Remember there are 192 LED'S even if you lose a few in the grand mix of the light the plants will be fine. Remember you have almost 1000 watts to start with and a lot of people are growing on less than 250 and if you had not looked you would not notice just don't over react and mess with things Sara will get your parts and your Girls will be happy

Check the water coming off your plant and see if the PH/EC is higher than what went in you might need a good flush

Thats a fantastic idea but I don't have the space just yet. Although its definitely got me thinking. Now what about comparing two 300w "old style" vs one 400w II? Or a single 600w "old style" vs one 400w II? Two 300w have more total combined LEDs but the spectrum isn't quite as optimized as the 400w II. When looking at the price two 300w or a single 600w would still be less than the 400w II so its kind of a toss up. Can you still get the old style on the website or just on eBay? So much to think about.....
 
Since they have been updated with 5w chips the 600w Old Style panel consumes around 270w , The 300w about 140w. The Mars II and reflector series gained 5w chips too but did not lose wattage in the process.

I say because the 3w chip panels before the upgrade consumed 360w and 185w

Reason is they use less 5w chips in the old style panels then they did with 3w chips ,but not in the Mars II / reflector series.

````````````````````````````````````````

Onward and forward

Using 1 of the 300w old that draws 140w in your 2.5x2.5 works out to*46w per sq ft*

A very nice percentage !

I think the Mars II 400 would be too Powerful for your space after thinking on it.

I am using some Mars old old :winkyface: version 100x3w Panels with great success.


They tell you to be between 30 and 50 watts per square foot.

Thank you this really does make me feel better, I've made the transition to led and the plants are doing great to be honest, bushy as hell and very healthy indeed. Nice one.
