Yields seem low

You need more light for bigger yields and bigger buds. Everything else sounds spot on.

I wasn't satisfied with my harvests yields until I upgraded to 1000w Double Ended HPS.

So I totally agree - I upgraded and got a 600w BD LED in there as well now, so hopefully that helps. But the interesting thing there is that I did a run where I ran a bagseed out of the 315 by itself and it churned out almost 2 ounces - not ideal, but not bad for a bagseed run. I think the big differentiator there was veg time (I vegged that bagseed plant for way longer than my next runs), and that it was the only plant sitting under the 315 at the time.

That being said, I'm in the market for a new light - how does the HPS do on heat? I feel like they typically get pretty hot, and I'd like to not have to vent heat if I don't have to.

I didn't see your groom room temp anywhere. Too cool or hot can impact yield. On fungus gnats, they are brutal on seedlings and early veg IME. Always best to get rid of them. Gnatrol or other BTI product works well and I believe the BTI is harmless. The BTI kills the larvae. Add yellow stickies to catch and monitor flyers and bottom feeding helps keep the surface of your medium dry.

Hmm - maybe it's that I'm not giving enough time for roots to spread out into a pot before moving to the 3 gal? I am starting seeds in solo cups then transplanting straight to 3 gal pots - should I be going to 1 gals first? I have friends who go straight from seedlings into 3 gal pots, and aren't having root issues that I'm aware of, so I didn't think that was a problem.

Not a ton of airflow necessarily, but it's also not hot at all under the ts 1000, so I didn't think to need much if any.

Maybe I'm off on frequency, and I had been watering closer to every 3 days, but the 500ml or so per pot is accurate. I'm assuming that underwatering could lead to less dense roots as well.

Yea go off of weight of the pot fill a 3gal with dry soil and pick it up feel it then water it throughly and pick it up and water again when it’s light again. And yea you still need good air circulation wether your lights get hot or not

This is not true, the 315 is a better light than that blurple led they charge a lot but doesn’t mean quality. It sucks but it happens. Same with nutrients you don’t need expensive nutrients if the company makes promises like this will up your yield or this will make your terps stronger, etc. you don’t need those they are selling a name not a product

Room temp oscillates from around 77-80 degrees. Have sticky paper up to catch the fliers, and am using diatomaceous earth and drying the soil to kill the larvae.

The dark glossy leaves and your analysis suggest nitrogen toxicity. Normally this reduces yield.

sorry, I misspoke - I meant upgrade in that I got a second light. Still have the 315 - just running the 600 in conjunction.

The blurple comment is true but all nutrients being the same is complete horse shit. If you grow some plants using House & Garden for example and then grow some using General Hydroponics you are not going to get the same results or quality at all. I know people that grow using GH and Maxi powder and their bud is bad quality compared to what they are getting now running a higher quality base nutrient. I do agree though TERPINATOR and all these additives are unnecessary and usually just to make $$.

You've been duped if you think that the cheap dry nutrients are as good as some bottled brands out there. House & Garden for example derives all of their bases from liquid not powder so you can't compare them like that. I can spill some of their nutrients on my work table and have it still be wet days later where you spill some Heavy 16 or General Hydroponic and the table is all crusted up and salty.

Interesting thought - my push back on that though would be that the Dolato was the only plant that had the dark, glossy leaves. Everything else looked fine, and they all received the same nutrient regimen.

Keep in mind that the LED wattage ratings are usually way far fetched. For example I own 6 Mars-Hydro TSW-2000 panels. Some people confuse this and think they are 2000 watts, the actual draw they use at 100% power is 300 watts. This does matter. Also avoid the "blurple" lights that look like a pink disco room they are honestly just a waste of electricity you're better off getting a quality light that is still in the budget range from a brand like Mars-Hydro or Spider Farmar.

Sounds good - yeah I don't plan to buy a BD when I actually go to buy. Thinking Mars is a good way for me to go considering how much I like the ts 1000 for veg.

So it sounds like you'd say that my low yield is mostly due to lighting - would you say that's right? I've said elsewhere in the thread - I've noticed that the root balls of the plants that I cut down with low yield were not that dense or spread out - not quite even filling up a 3 gal pot. I'm thinking that overwatering in veg was the culprit there, but I've had others here tell me that they water half a gallon every 2-3 days in the size pot that I'm working with, and I'm definitely way under that.

most likely you need to veg more before flip


the bd and cmh should be enough to get that goal
Click to expand...
Hmm - could be that. I'm going for around 4-5 weeks on veg before a flip, so I feel like that should be enough...I can go 5-6 weeks though and still keep my schedule, so I will try that.

Three pages of discussion wasted. Why the deep dive when lighting is clearly not the issue with a cmh.

Just would hate to see you sent in a wild goose chase.

I wouldn't call it a waste, there are many things that can lead to reduced yields. i don't see any serious n tox or clawing
