Are you growing other herbs or flowersin that pot to keep mites away?? Thanks.
Well the only con isnt really a con, except this time of year. Im about 7 weeks into veg and have been running a space heater for 6 of them. These lights run so cool i had to add heat, i even added a 65w cfl just for its heat. Im thinking i need to add some cobs as id rather be making lumens than just btus.
That said, im curious about distance to clones/seedlings with the HLG 40. I have a 26" long shelf i use to clone and germinate. The 40 looks perfect for it but I don't know how high above I would have to put it.
Have a good weekend my green bros ....
Had to load a twisty and grab some beer for a visit to ol mother in laws pad - she thinks I smoke clove cigarettes ( which are disgusting ) and she drinks shit beer ( so some ales are coming with me ).
It's one of those " women blab fest " so I will just puff and drink .....
how many inches away from the canopy should quantum boards be, if running at ~90-100%? similar to regular LEDs or...?
awesome Pros n Cons list btw mate thanks
Light is 2-3 above canopy.
This kit can not be dimmed.. or I don't see an option anyway.
Clover and beans for nitrogen purposes. They release N back into soil when chopped and dropped. Marigold flowers are known to encourage nearby plants to increase resin production. I'll be throwing some basil seeds in there to deter bad mites.
I think it just depends on the driver, and from what ive seen you need a phillips head screwdriver to adjust it on those Meanwell HLG's
I think too little heat in winter is a better problem than too much heat in summer.
Both can be reduced with good insulation. Adding heat should be cheaper than cooling air by a similar amount.
Those plastic screwdrivers you get with cheap pH pens are best for the trimpots.
btw what does "BIN" mean? eg S5, S6, "top bin" etc ... my googling sucked
 ok i see it's https://en.wikipedia.org/wiki/Product_binning
They do this with CPU overclocking too
Half way through chop and I thought I better post a pic while I some are still in the land of the living.
If all estimates are correct going on my usual wet-dry weight ratio I might just be hitting 1.6 GPW with this run.
Will be another PB for me and the quantum boards..... Gotta love HLG!
Will let all know final weight once dried and cured. Will be over 2lb from 2x 260w kits in that half of my 8x4 flower tent regardless.
Last pic is four blue dream on the COB side.
All others are part of one of the two I have left to still chop. (incredible bulk)
They can be binned for similar colours or similar efficiency.
Its like grading eggs!
Great work! Did you measure the light you were actually putting down on your plants to get 2+ pound from your 4x4?
Do you mean have I measured the light with a light meter? I have not done that, one day I will buy one though because I like toys.
Its 2x 260w kits which at the wall is 285w per kit though.
I did try and measure by eye once, it turned out to be blinding..
I only have a LUX meter. Cant bring myself to lay down $500ish for a top quality par meter. How high did you run the QBs from the canopy? Thanks.
Yeah I know what your saying.
Boards are about 2ft or slightly less above canopy.
GL offers a dimmer for it.But ya gotta pay the $50 for the kit to be put together and tested in order to have the potentiometer(another $20 cost)installed as they test everything first.
rapid led has an apogee par meter you hook to a multimeter. Its 150$. quite worth it id say
Looks like choppy chop in the next two days -----
Flipped go 11/13 last week in their last wk10 so ... TRICHES looking opaque and most of fans drying off. They been on water for a week ( water twice ) and noticed more accelerated cloudiness so time to get the FISKERS ready.
True, but the "full spectrum" version is still about $350ish. Check out this page:
Just don't want to leave all those photons uncounted!
