marshydro

Hi team, Still a bit of a freashy here, only on my third go and have had great success but only do one at a time so it's a slow learning curve. I have a g13 blueberry gum that I begged for nearly 3 months. It's in a 52ltr pot now and is in its 5 week of flower / of 8 apparently but I think...

I'm not too sure which one it is. I'm assuming it's all of them. 5th weeks in hydro. Sour Diesel. 300W LED (140 true w). 5 gallon bucket. Hydro with clay pebbles. I can't figure it out if it is magnesium problem due to the pictures and or potassium problem. There seems to be a lot of problems...

Hi guys, I'm new here.. So I started my first grow the other day, popped 3 Snow White seeds from Nirvana and put them under a 125w cfl they seem to like it. However I want to upgrade to LED for veg and wondered if anyone could speak good of the MarsHydro 300? Any help will be appreciated, cheers

Alright, I currently have a barely used MarsHydro 300W (132 True Watts) LED. It's currently collecting dust since I've been unable to sell it. I've read enough posts to understand I should have never bought it to begin with, but now I'm trying to find some use for it. I'm considering settings...

So, I felt it might be prudent to create a thread for new jacks here getting into growing. I don't mean to insult anyone, but when I look around and see some CFL grows, I can't help but shake my head, because it's kind of sad. It's not just (in my opinion) pathetic due to yield potential, but...

I currently have a grow going in my 3'x3'x6'11" tent. I'm using a 315w CMH light. A friend of mine gave me his 2 MarsHydro 300 LED lights. Would I be able to use these in any way to help increase possible yield, or should I use them as door stops?

I was curious to know if anyone has an opinion on the veg. and bloom switch on the MarsHydro Reflector 192. Would there be any marked benefit to using the individual modes during the proper growth phase, or would I be better off just running full spectrum the entire time?

Yes, I know these lights aren't the best nor are they the worst. I had planned on just going with a HPS (can't afford the nicer COB LEDs), but a friend of mine has a couple he's looking to sell. They have gone through 2 harvests. Given the price point he's offering me, they're a good enough deal...

Driver specs: model: PT1004F-60W (60W) in: 100-240V out: 55-100V (0.69-0.72A) Can I run three CREE CXA2540 on one driver? I am still not understanding how this works. So 3x36V COBs like the CXA2540 (I mention the CXA2540 because I can get those VERY cheap) = 108V - but 108V@0.7A = 75.6W. So...

When I get my new COB lights on Wednesday I will have two 300W Marshydros over. My plan is to convert them to additional COB lights, with 4x CREE CXB2530/2540, using the Marshydro Case and drivers. (The drivers of the MH by the way are 2x60W, out:55-100V@0.69-0.72A) (The plan is to make...
