Cheese xxl day 14 White sirius day 14 Amnesia day 7 What do you guys think. Any advice would be appreciated. I am going to add a fan here soon. Thinking about getting the tower oscillating ones, or do you think the round ones will do? If I could find fans and build a frame, and...

Pretty new here. This will be my second attempt growing in the greenhouse. Last year I tried a GSC photo from reg seed that was given to me from a friend who got it from Colorado. It grew 7' tall and got mold problems 3/4 of the way through flower. I had no fan in the greenhouse either. I...

If you go 1 driver per 2 boards, I would go with the hlg-240h-48a or b. With the B you could get 2.5a per board, and slightly more with the a model. The more you max out a driver the more effecient it is. So if you need all that power, go for it. If you don't need all that power step down a...

If you want to run 2 drivers on 1 meanwell hlg driver. You need a 50k ohm linear taper potentiometer instead of a 100k ohm linear taper potentiometer.

That's what I was thinking. Thanks for the confirmation. = )

A little update. My seedlings seem to be going pretty strong. Here is my amnesia auto White sirius auto And finally cheese xxl The cheese xxl is just taking off. It should be ready for transplant here soon. When I go to transplant it should i bury some of that stem? It stretched a...

= ) glad to help.

Those are some top of the line leds. They grew your plant over 7' in 1 day. Holy shit I want some of those leds, or some of whatever it is you are smoking!

With the new qb 288 v2. You can actually run six boards on two hlg-320h-48 at about 109w per board. That would run them at about 2230mA a piece. The 320h-54 might not run them as it's a 49-58v driver. On the website the boards are rated 45.72-49.86v. Running 6 boards on an hlg-600h-48 would run...

Holy shit. That is a tree!

Look at ledgardner.com. read his blogs for the strip builds, watch his videos on how the meanwell drivers. Start studying the data sheets on whatever strips or cobs and compare them to the meanwell driver spreadsheet that led gardner created. He also has a tool to calculate drivers for strip...

Ok, this is understandable for the a version of driver. You cannot set the voltage on the B or regular version. How would it work in my example with the number of strips not maxed out?

If you look at the spec sheets the constant voltage drivers have a range of voltage they run at. Example a 42 V driver may be able to run between 38-45v depending how many amps that driver puts out, and the wattage the driver is rated for.

So a strip will only pull as much current as the max volts of the chip or the driver with 1 hooked up to a CV driver?

Understandable.

I ordered from seedsman. I played with bitcoin. On your first bitcoin order you get 25% off, and 15% off subsequent bitcoin orders, and 8 free seeds on every bitcoin purchase. It only took 20 mins to set up an account on coin base. The seeds I got weren't as dark and big as most I've seen from...

Thx. It does for a tiny little fellow. My cheese xxl from Dinafem stretched a bit at first, it got a little flimsy. Propped up with sticks for now. The white sirius is also going strong. It's short and stout for now.

My newly germinated amnesia auto from lineage genetics popped after 1 1/2 days of planting. = D my problem was I wasn't getting the soil thoroughly soaked before planting... Damn noobie lol. This pic is at day 2.

Yes my mistake. I edited it to fix the mistake.

If you want to get max power out of these boards, and plan on expanding in the future, I'd go with an hlg-240h-c1750b and an external pot for dimming, this will give you 135w max With 3 boards. If you add 1 board you get 180w. Add 2 you get 225w. This is all wired series. If you don't plan on...
