    LED lighting and deficiencies

    I am running 3.25g Jacks 5-12-26, 2.4g Calcium Nitrate, 1/2 teaspoon Magnesium Nitrate, and 2.5 ml Thrive Alive B-1 per gallon with PH at 5.8. Here are three different strains that I started cloning 20 days before this picture.

    In a perfect world how far from the canopy would you like your lights?

    24 inches. Room to look over plants, work on plants, and not have to raise the lights everyday as the plants grow.

    DIY Samsung LM561C build

    I have ordered from Roget. It was about $1,500 in all. It took a while because the tolerences were very tight for the diode placement. He could not use his pick and place machine to place the diodes with out the diodes falling off the strip. So he had to hand place over 20,000 diodes. It...

    Geyapex LM-P4 Unboxing and Under the Hood

    The brown and blue wire coming from your driver connect to a red and black wire with a quick splice. On the red and black side the insulation has been stripped to far back and leaves the wire exposed. You need to cover the exposed wire or cut the wire back to the correct length. If this comes...

    You would need 2 relays. The first one is set to 8 and 16 hours. The 16 hour side is followed by a second relay also to 8 and 16 hours. The second relay set to 16 hours would use the 8 hours that the first relay is on plus half of the 16 hours the second relay is on.

    The only draw back I have found with the narrower screens is that the plants can be harder to bend around because of the tighter bend radius needed to get them back on the screens. But love the fact that the screens can be taken out at any time.

    I like them to sag as well to get light in farther. But you have to make sure the branch does not split where it joins the main stem.

    I could have put it in smaller and let it fill in but it was the first time I grew it and I was new to growing so let it go. Now if I had it I could run it better but there are better strains available.

    No all this was after going into flower. It stretched about 3 feet in flower. Not a good choice for vert.

    What are you going to do if the buds above the top of the screen get heavy and start to flop down? I built smaller screens that can be attached to the top of my larger screens just for this reason. I installed PVC tees at the screen corners and the small screens just slid right in. Some thing...

    I asked where you were because if you are in the USA you can go here to get crop netting cheap. http://www.memphisnet.net/category/hortonova-crop-support-netting2 Get the 6x6 not the 6x7. It is much easier to cut to size.

    Yes you are right. Still driver selection can eat that up. Say a 86% driver verses a 94% driver. That is way more wattage use than the chip. Also drive current can balance the two by running more 561 diodes at a lower current. And if the price is high on the 301 you may be able to pack your...
