Chlorine dioxide would work well for this. It's a gaseous sanitizer, so anything that touches air will be sanitized. Biocide is the brand I use at my commercial mushroom farm, I gas the clean room before doing inoculations. Each one of these containers will sanitize 4,000 cubic feet...

Maybe it's just my education (double majored chemistry and physics), but needing calcinit and epsom is pretty well implied in a thread on Jack's.

This stuff stomps the shit out of Jack's, megacrop, floraflex, vb, all of em. You only use 2 grams per gallon because they use USP (pharmaceutical manufacture) grade salts. https://hydro-gardens.com/?s=4-20-39&post_type=product

I grow autos outside in the spring, because our county has 700+ acres of hemp dumping pollen all fall. They're great plants, I've been getting at minimum 5 oz from them outside using mephisto.

Uh, the 315 lamps even have a UV warning on the box. ‍Please refrain from giving outright false advice, it shows you have zero clue but are willing to give opinions in place of relaying facts. Google takes two seconds to look up a spectrograph.

I'm close friends with guys who run a commercial facility that uses fluence lights, indicocolorado. If you follow fluence on Instagram, you've seen a lot of pictures from the indico facility. The new gen of fluence lights are pretty incredible, if you've got the money they're worth every penny...

It's okay, but way too expensive and low purity for me. The lower purity is due to using non USP/pharmaceutical grade salts. Check this stuff out, you only need 2 grams per gallon to hit 700 ppm with 2 grams calcium nitrate and 1 gram Epsom. It doesn't have the same ridiculous markup as the...

Aren't all of the meanwell hitting max efficiency anywhere above like 80%? The 600h hits max efficiency and stays there from 50% for anything other than 110v.

I don't remove sites, just fan leaf, biomass is biomass and if you're feeding right it doesn't lower yields to leave lowers. If you have the right vars the bottoms are still super frosty too, makes a great hash or RSO/FECO source. Nah man, 1 plant per square foot is pretty generally accepted...

Does your irrigation line loop? Mine forms large circles for each row to ensure the same pressure from first to last site. This is 1 of 8 rows for me, and this system works perfectly. I grow 3 plants (7 gallon trees) per 4x10 row, one for each manifold.

Near UV (415nm) does the same thing to the plants as UV, without destroying your grow room.

Cut out a section from stud to stud 30cm/12° high and check inside the wall. It's easy to replace a square chunk from stud to stud and you will know for sure. I've also worked doing house remodels and maintenance for a landlord. I've seen enough water damage to know it almost always needs...

1. Black pin mold (Stachybotrys chartarum), which is extremely toxic to some folks. 2. See my above post. You also need to add enough heat so that you don't have more than 2-3° temperature swing from day to night. Temperature swings will lead to condensation. 3. I just replaced the damaged...

Hey @auto_grow I own a mushroom farm and this is a daily battle for us. IMO, the best product you could use in this situation is gaseous chlorine dioxide. I use bio-cide brand and citric acid as the activator. Since it's a gas it will sanitize every nook and cranny that touches air, and...

My worms from uncle Jim also came with predatory hypoaspis mites. Win win.

The 4000 would need two of those ELG drivers to hit the advertised wattage. They might use two drivers, but I doubt it.

Damn man, 4 gallons a day is a lot. I do 3 per 4x10 space, so they're about 13.3sq ft each, easily over lb per, and only drink 1 gallon a day. 7 gallon containers of Coco coir + 5% castings, couple mineral powder amendments and dried ground cannabis leaf as an amendment. I do micropulse...

Ha, I responded to this thread on reddit. I'm the guy who broke down a cost analysis on that heater vs flower cost.

Nope, 80 cri.

It's splitting hairs, really. I commonly hit 2+ gpw even with 4,000k lm561c. Focus on environmental optimization, especially humidity and air flow. It's going to make a bigger difference than minimal diode changes.
