I fail to see the problem with asking if he was a right wing idiot or being sarcastic. Have you read some of the horseshit that gets posted here?

If you email Mary at [email protected] she can probably get you a better price and let you know when the US store will be back in stock. I've used her for tents recently and she was quite helpful.

Sorry ... I missed that Yes, that's the one ... although you'll save sales tax if you buy it on the mars-hydro site. The reality is that you can veg under a wide variety of lighting options. Ideally you want to have a blue leaning spectrum and enough micro moles of photons so that you maintain...

You clearly haven’t listened to the empassioned bleating from the brainwashed herd on the right. Glad it’s sarcasm

Are you being sarcastic or just a complete idiot? That statement is as idiotic as the people on their death beds in the Dakotas denying they could be dying of COVID because it was a hoax.

You haven’t told us what your budget is so suggestions are difficult. I will preface this suggestion with an acknowledgement that suggesting anything Mars-Hydro usually evokes screams of rage from HLG fans. That said, you should look at the SP150. Ideally, 3 of them would give you 450 true...

Here are a few things to look at https://dcseedexchange.com/product/the-durban-special-blueberry-og-3-cookies-cream-x-durban-poison-7-12-regular-seeds/ https://speakeasyseedbank.com/offerings/riot-seeds/trademark-chad/ https://www.cannabis-seeds-bank.co.uk/index.php?searchStr=durban&act=viewCat

You have the prefilter outside rather than inside the filter. This only works properly of the filter is in the tent and you're pulling air through it ... it's useless when you're pushing air through it. To protect the activated carbon from clogging, you need to put the prefilter INSIDE the...

You should look at the strain profiles on dynastyseeds.com/ ... on most strains the professor details what phenos you're likely to see and how likely each one is. He doesn't have the strains @Mac1981 is looking for but the detail on most strains is a model for what better breeders should have...

Please describe your grow in detail Dimensions, lights, plant type and count, container size, nutrients, growing medium, watering schedule, etc

The main purpose of supplemental CO2 is to allow your plants to fully utilize all of the light they are receiving. The threshold for supplemental CO2 being necessary is bewteen 900 and 1000 micro moles. If you have powerful lights, CO2 may well improve your grow ... otherwise you're not going...

If you’re not producing close to 1000 micro moles over the canopy there’s no need for CO2.

If memory serves (and at my age it doesn't always) UV-B is necessary to cause the damage that produces the protective reaction in the trichomes while UV-A aids in the recovery. Since decriminalization and legalization has allowed commercial grows, there has been far more research on how to...

Actually there's substantial science regarding the benefits of UV. The problem for LED mfrs is that UVB diodes run too hot and burn out much faster than the whites and reds. In order to get the real benefit of UV you really need some UVB and almost all the fixtures on the market only have UVA...

Gentlepersons May I humbly suggest that we start a new thread to continue this substantive discussion of photon / canopy interactions? @DukeFluke still needs to decide on a fixture and I fear we're not helping him.

Discussion continued :) First and foremost ... he can never have another cup of coffee or energy drink again. Now to the comments on LEDs and photon spread, and and canopy penetration. I will preface my comments with the fact that using a Fluence 2P in a 5x5 tent with no CO2 I had a fixture...

Before you extol the virtues of the scorpion or the diablo look at their published ppfd reports. The PAR map for these things is awful. https://cdn.shopify.com/s/files/1/1538/8585/files/HLG_Scorpion_Diablo_PPFD_Chart.pdf?v=1601665090 HLG is a good company, but the quantum model, which was ahead...

If price is not an object, the Fluence Spydr 2i is probably the best light on the market.

It's always valuable comparing innovative technology to existing standards. I just wish you had selected LED options with better PAR distribution. Both of the fixtures you selected are heavily center weighted and while the do offer quality builds, they leave a lot to be desired as far as...

I know you’re askin* about seeds but they’re the last piece of the puzzle. What’s your grow environment look like. Tent size ... grow style / medium ... pot size ... lighting ... nutrients Your choices may affect what stains you want to start with. Even with the best advice it can take multiple...
