    Default Bespoke LED strip build mentored by Gardro

    First off, big thanks to Gardo who's kindly agreed to guide me thru this build.

    Currently I'm using 400w of cfls. I'm happy with the results but aware I could be more efficient and get smaller leccy bills with a LED strip system... tho cfls do help with heating the tent in these cool months, I'm not sure how manageable it'll be in the summer months.

    The tents insulated and hidden beneath a worktop, hence the low height. Wish I could go bigger but this is it for the foreseeable future.

    I'm guessing power will be around 105w to 175w if I'm doing my calculations right...ish. I was thinking of having 2 drivers so I could control left side and right, but now thinking I'll go with just the one as I can't really see me having 2 plants at drastically different heights.

    Looking forward to this... no idea what tools I'll need but I'm guessing I'll be learning to solder? Heard Samsung are the best strips so I'll aim for those if poss.

    Cheers again Gardo, take your time, I'll be on here constantly so won't leave you hanging when you do get the opportunity to instruct

    Thanks Silks, good pic there to help me visualise the setup

    Risk here is of course the low height. It goes without saying you will have to be a master pancake grower.

    Coming from cfl this is going to be a big change for you and you will lose quite a bit of height from your space due to minimum light distance being much greater.

    Given this height, I think we should forget the higher density options and opt for Q series. These are the most efficient strips currently available and based on LM301B (as per Gaz)

    Assume we can fit 2 footers in your space, actually 56cm long

    Not knowing where you are in the world can you put the following part number into findchips.com to see what stock we can source (just a parts search engine)

    SI-B8V101560US

    This is 2 foot Q series in 3000K

    Hi Gardo, I'm in the UK btw, off to take dog for a walk but will look up prices this afternoon.

    With the Q strips, roughly how close will I be able to allow the plants to get the them during late flower? The cfls take up more space so I was hoping that would compensate for some of the added distance strips need.

    I would say you need a good 8 to 10 inches but having said that, the total par will reduce as you get closer to the bad boys since the led overlap is lost ;-)

    That might not be too bad. The cfl, reflector and hanging hook prob add up to about 7 inches, plus the 2 inch recommended gap means I should only lose an inch or two... if any. I love the look of em, so tidy and uncluttered compared to having 2 lights, reflectors and yoyos getting in the way.

    Had a look and I think digikey might be the best bet. The other 2 cost over 30 quid shipping whereas digikey is free delivery. 2ft strips are a tennerish each.

    Don't know if you've seen these Silk but the next few months are going to see Samsung drop their first horticulture designed strips with some different diodes and reds added in to the mix. The L2 I think they were called, not too hard to find on google.
    I think the Q series is still likely a better bet due to lower diode density, like Gardro says, but might be worth reading up on at least?
