don't forget about jack's tomato feED, it's a 12-15-30. if you've got water with plenty of calcium you don't need to add anything but epsom salts.

flexible LED tape using the samsung lm561C, these make 184 lumens per watt and are also made in america. this company has several models available using those chips. http://luxtech.com/product-detail/flexible-led-tape/ http://luxtech.com/product-showcase/linear/

mix vinegar and hydrogen peroxide 50/50, it makes peroxyacetic acid (PAA). i use peroxyacetic acid in my tissue culture lab, it does a far better job at sanitizing than bleach! it's great for removing bio-film from surfaces and cleaning my laminar flow hood bench...

you're not the only one who has the desire to grow with several different lights. i've grown with two different brands of 400w CMH (GE and philips), 315w CDM, 860w, 400w hps/mh, 1000w hps/mh, 250w hps/conversion mh, and three different brands of LED. do you know what from that list gets the...

those bulbs make 34,000 lumens for 600w? might as well just hit the atm and withdraw your money, then flush it down the toilet. i have a 200w fixture that makes the same amount of light. the 315w CDM makes 33,000 lumens! at 56.6 lumens per watt that's ~20% efficient, so the other 80% is going...

would it work to do a chunky coir or chow mix watered several times a day as long as you had enough plants to meet filtration requirements? i think there would be a balance between daily waterings, runoff, and plant count that would have to be ironed out, but it seems viable. i use a water...

i use jack's tomato feED in soil with tap water and it crushes. works out to the same nutrient profile as the hydro and calinit. most feed and farm stores will have calcium nitrate for dirt cheap, and since it's the off-season they might even be having a sale.

looks great tang, you're really showing that autos can do it, just takes skill.

it stays in the 70s, the room is on a 12/12 split, 300w at night, 200w during the day. both the COB tents and my mixed source room run at positive pressure. tents pull cool filtered air from the bottom of the room near the floor and pass the cool air over the heat sinks on the way into the tent.

are the optics you selected for your grow different from the ones normally offered? if so, would you care to expound on the concept? your grow definitely isn't having a problem with bottom branches receiving enough light!

personally, if i were doing only 315w bulbs, i would do 9 lights, three rows of three. but i am running a 315w/COB combo room currently, and it is kicking the living shit out of the COB only grows. it's lower wattage per square foot, more frosty than the COB only, and more solid farther down...

nice lookin' spring garden man! is that a meyer lemon tree you're growing? i've developed a bit of an obsession with them recently lol.

hey @pin head nice to see another myco-nerd around. i used to run a penis envy clone that was labelled "prof pinhead's PE", wonder if it came from you. got it from a mycotek guy i know IRL. funny how mushroom clones get passed around the same as herb, just less often.

it's crazy how blessed you are to live in a place that is so forward thinking. where i'm living i got a year in prison and 4 years on parole for 2 pounds. i can't wait to move, i don't even want to participate in the CO cannabis industry, just live in a place where i can produce my own instead...

i'm so jealous of the fall mushroom season you west coasters had this year. porcini and chanterelle went crazy! i've never been very good at finding morels, the micro climate where i'm located is much warmer than the surrounding area in a several hour radius. i'm using hardwood fuel pellets...

haven't added any other farm pictures in a while, here's a catch up. one of the pepper harvests from late summer cultivated maitake (grifola frondosa) yuuuuge mushrooms 1+ lb king oyster fruit (pleurotus eryngii) sporeworks pleurotus citrinopileatus 1.5 lb lion's mane...

it most definitely works with the magic variety! ;)

would you mind providing some more information on the poke-in connectors? what's the manufacturer's part #?

the other option would be to purchase some mushroom grow kits. a 5 lb oyster, lion's mane, or shiitake grow kit adds about a pound of CO2 over 2 weeks. lots of positives to using mushroom mycelium for CO2, you end up with some (1-2 lbs of mushrooms) food, can add the spent substrate block to...
