Grow light question

Hi folks,

Just bought a Phlizon grow light 2000w with a veg and bloom switch but no dimmer. I didn't have many options and this was available. Now the veg cycle has red lights aplenty, wont that make my plants flower?

I blundered my grow this time. The seedlings grew fine till about a week and due to low humidity and overwatering stress. Some of the small plants started flowering even on 18-6. I removed then from the coco substrate, cleaned the roots and some early budding sites. I then stuck them under 24-0 blue lights in hydro. They recovered really well and have started to reveg.

As i want to clone, i got this extra light for them but as they are so susceptible to flower, will the red in the veg spectrum cause problems?

Thanks.

Your plants will be fine, even in veg they can use the red spectrum as well as others. Abit more blue in veg helps keep them more compact and helps with thicker better leaf growth. When you put the bloom switch on do more red and white lights come on ? Is there any way you can put up the light model number. But you will be fine the red wont trigger flowering just like that. Your plants shouldn't have started flowering under just 6 hours dark unles there some auto genetics in ther or you left them in tiny pots for way too long and the tight root space can trigger flowering too in some plants. Check your timer properly too.

Thanks, i did forget the lights on one occasion so they got 24 hr dark period. The new light does have more red and white when bloom is on. I guess that should be fine then. The concerning point is that even in hydro with a 60w mostly white and blue (some red) at 24-0, two were pushing out pristsels. Now ive got them under only blue and white light and they seem to be vegging fine, only loss is the parts i had to nip the buds from. I guess i wont get growth from that node site? Thanks for the answer and help.

Are you growing autoflower?

Plants in veg will show pistils (hairs) once they are mature.

I'm not sure the stage of your plants. Color of light will not change the plant's stage of growth. The hours of light will be the deciding factor in that.

Both the ones on the right are apricot kush (photos) and we're forming pistils/sacs. This strain is not the best and has hermied before. One at the back is fem, front is male.

The one on the left is a batch with mixed seeds which did contain autos in them. Could possibly be auto, but then it has reveged after I changed the substrait and had it on 24h lights (do autos reveg?). If it's not an auto, I hope to make that a mom plant.

These three in the aero garden are from the mixed seeds with autos in them.

The one on the left was completely flowering still very small, so instead of counting it as a waste I just nipped it all expect for the bottom growth.

The other two seem to be growing normally.

For complete context:

My second grow, overconfidence took it's toll and I experienced all the things I was careful to avoid the first time. I over watered them and this led to stunted growth and yellowing of the leaves AND started flowering, didn't realize it could be that basic till I saw the roots which looked unhealthy.

I cleaned them up and put them in the aero garden under 24-0 and they perked back up hence the good color on the top growth. Once they recovered I got them in coco again and under blue/white light and it seems to have worked and the top looks healthy and reveged. They are under 24-0 blue / white light last 4 days.

The most healthy seedling with strong growth was flowering all the way down to the 4th node and yet very small so I nipped it and it's in the aero.

Lol that's the whole story and not pretty but has a good ending as they have reveged and doing good now. Hopefully .

Where I am seeds are hard to come by and so the kush male/female I'm going to grow just for seeds.

From the others I hope to get a mom plant for clones. Another mission and luck to get a photo mom from them but out of 4 I'll just need one lol. It's a fun story at least . The rest I'm hopeful to get some buds from and all is good with the world.

EDIT: wow those pictures turned out to be massive, sry about that.

I'm guessing that the light is not anywhere near 2000w...most likely ~200w knowing how they name these. I'd leave both flower/veg lights on and run it full out no matter what. It's not color that triggers flower anyway.

It's got some weight to it, no idea why. I have another advertised as 1000w like this which didn't help at blooming the last batch, seems good for veg. Another 1000w I have is decent and I got a moderate yield from it in the first grow.

Post up which model it is. Any light that's advertising veg and flower settings is giving me bad feels anyway, but most likely whatever it is, it will say what the light draws or consumes for wattage, that's the actual real wattage of the light. There aren't a whole lot of real 1000w or 2000w consumer grade LED light fixtures in the world, and certainly not at bargain prices.

Those pots look awfully dry, assuming you're running straight coco/perlite. Possibly stressing them from treating coco like soil. Might make sense that they'd recover in the Aerogarden since they're getting enough water in there. Just a thought.

Just ordered a Mars hydro fc 3000, not risking all this effort for nothing. It's advertised as 300w and has great reviews, so should be good.

You're right, I'm being extra careful. It's this dry winter, makes the top look dry but there is actual run off from below. That's how I over watered them earlier. Those pictures is about feeding time anyways. Thanks.

Kinda hard to overwater in coco. Having them sitting in their own runoff on the floor is a very bad idea. I think you may need to rethink a lot of your setup.

I over watered them as one week old seedlings, as the top looked dry most of the time and they were in plastic pots before. I have them in these porous pots now. And I guess I'm not using the run off term correctly here, I meant there is moisture below the pots, not standing water. But yes, that's what I'm here to do, learn from the pros.

I'm almost a month into my first coco run, so I'm far from a pro. I started my seeds in 4 inch plastic pots. By the time they were a week old, I was feeding daily, a few days from starting to feed twice a day. Coco retains a LOT of air, so over watering isn't typically a thing.

The vast majority of growers I see posting treat coco as a completely different animal than soil; feeding with every watering, fully saturating the post and getting a good amount of runoff each time, and doing that at least once a day. The pots really should be in a drip tray of some sort, sitting up off the floor. You don't want them to reabsorb everything that was flushed out with the previous feeding.

The people I see posting that treat coco as soil pretty much always have serious issues. Hopefully one of the actual pros can post some good links to the resources that go into the most effective ways of growing in coco.

EDIT. My cheap and simple coco setup. Gotta keep the girls up out of their drainage.
