drainage in the soil is extremely important, if the drainage is bad you will suffocate the roots and badly damage the plants, so you will want to mix medium with perlite at 50/50 ratio, and look at the soil you choose for any info on drainage. Perlite should be available at garden stores...
if anyone is interested, having good results so far, at about day 24 and after watering, no signs of overwatering, they did droop a little after the water so i was worried but they were back to normal within 3-4 hours, and the autos are nice, big and healthy. The medium isnt as hot as i thought...

2 waterings without cal mag?
its possible that its really hungry for that, and missing it 2 times has caused a deficiency.
Its often difficult to diagnose these problems, as lots of things look very similar. Its just interesting...

yeah from what i can see it looks like magnesium or another trace element deficiency.
I assume you pH your water? wrong pH can affect the uptake of certain things.
I did see a grow that said that his northern lights was...

if you are interested this guy has grown a vast and fast, and is starting another run of them, might be something interesting for you. He got OK yield (2oz) from a tiny stumpy plant.
interesting grow to see. Thanks for putting...
thanks :) I bought 1 bag to test it, seems fine so far, was a little worried it might be too hot for autos but have no burn so far.
decided to mix 50/50 perlite, havent done a full water yet (plants are at 2 weeks so first full water will be soon, will leave update if I get any overwatering...
My last run of autoflowers has been a terrible failure. Before this I had no problems getting a decent yield. I think the problem may be with my soil (basic potting compost mixed 50/50 with perlite) Before I used cheap potting soil too, but a different brand. It seems that overwatering is...
we have similar problem in UK, a decade ago it was moved from a class B to class C drug, and users were subject only to confiscation. Of course it was moved back and innocent people were being prosecuted again. Now we are in the situation where the issue is essentially ignored, with flat...
If anyone is interested I picked up the 300W old model, and am very happy so far. delivery was super fast and was packaged well, and the unit was undamaged and all LEDs were working. I could have tried a more powerful model, but in the small space it seemed fine for me. The price was so good for...
the 400w uses 5w diodes though? I read that these get very hot, im not sure my current setup can handle it, particularly with summer coming.
I am leaning towards the 300W right now.
Hi there :)
I am looking to upgrade my light (300w CFL mixed spectrum) to a mars hydro LED. Mars seem the best choice as I am on a budget, and their prices seem amazing, and they are well reviewed all around.
currently I am growing 4 auto flowers in a 80x80x160 cm small tent.
the lights I am...
