Choosing Wire for Your LED COBs

Due to the low-current nature of most LED COB systems, most of the wire you find lying around should do the job. There are, however, a few considerations you should make to ensure what you’ve got will fit the bill.

2016-2017 Winter Grow: 12-29-16

Hey all!

This week marks my first official “harvest” from my little indoor garden. I noticed that some of the older lettuce leaves were starting to get a little wilted so I decided I’d chop a bunch off to make myself a nice little salad. My last basil in soil died, but I still have one going in coco, so I’m happy. I think I’ll use the extra space to try growing some garlic, which I was reading about the other day. It looked like fun, so I’m going to give it a shot.

Wiring Identical COBS in Parallel on a Constant Current Driver

I’m away from my plants tonight so I’ll have to update my grow tent progress tomorrow – here’s a little video I recorded instead!

Constant Current vs. Constant Voltage Drivers

When it comes to wiring LED COB circuits, series configurations with constant current drivers are generally the easiest way to go – especially if you’re new to electronics. Since LEDs are semi-conductors and operate a little differently than most basic circuits, it’s far easier to simply drive them at their rated current with a constant current driver than it is to try and produce that current by providing a constant voltage. If you check the datasheet and find that your LED COB has a typical forward voltage of 36V at 2400mA, you don’t want to strive to give the LED 36 volts, you want to strive to give it 2400mA at whatever voltage that current happens to occur at.

2016-2017 Winter Grow: 12-21-16

Today was a big day in my little garden.

I picked up more soil and a buttload of 1 gallon pots on my way home from work, and finally potted up my plants! A good chunk of them were on the verge of becoming root bound, so I’m glad I didn’t wait much longer. I decided to mix in a bag of perlite with my soil in an attempt to improve aeration. Hopefully these little guys transition smoothly – it’s starting to look like a real garden now!

5 Essential Tools for Building Your Own LED Grow Lights

If you’re considering building your own LED grow light but don’t own a lot of tools, don’t let this stop you! There are only a handful of essentials that you’ll need, and these are tools that many people tend to own, so you can probably borrow whatever you don’t have if you can’t afford to buy it. The following is a list of the most important tools you’ll need to build your light:

2016-2017 Winter Grow: 12-14-16

Time for another little update. For the most part, everything is going well but the basil is basically all dead. Even the new leaves aren’t looking good – I think they were just in too bad of shape to recover. Fortunately, I do have one basil left in coco that’s going strong! The rest of the plants in soil are looking really good.

The coco plants are getting a bit yellow, so I think I’ll have to feed them again. I’m going to give them another day to dry out a little more, then I’ll hit them with some nutes…

Grow Space & Changes to Tent and Buckets

 

2016-2017 Winter Grow: 12-07-16

In the first week of December, things went well for everything in the tent… except for the basil. Something has gone terribly wrong!

A Mass Basilcide

I came downstairs one morning to see that the fan that usually blows air into the tent had not come on, and that humidity was 100% in the tent – all the plants’ leaves were covered in water droplets and I think this may have caused the mass basilcide. I think the water droplets on the leaves may have magnified the light coming down from the COBs and blasted the basil, but the thing that doesn’t agree with this theory is that the tomatoes, which are taller, seemed to come out nearly unscathed. Some of the tomato leaves are a bit crunchy now, but I think they’ll be fine. The basil, on the other hand, will be touch and go.

3000K vs. 5000K LED GROW LIGHT SMACKDOWN

Okay, maybe that title is a little sensationalized. This is hardly a smackdown – it’s barely a schoolyard slap fight – but I’m gonna stick with it because it’s so dumb that it made me laugh aloud when I typed it. Today I kicked off a new lil’ experiment in which I’m going to compare a 3000K vs. 5000K LED grow light.
