How much light is too much for the newly sprouted?
KannabisKaystarted grow question 4 years ago
Hello!
I have put my 7 day old auto cbd cheese seedlings into my 25x36x57 tent with a 1000LED as there is no sun outside today. How far is a safe distance away from the light for such younglings? They will eventually be a tent grow under 1200 watt LED in a 3x3x72

Yeah, what the others said. Tho, I'd say a couple of minutes rather than a single one, just to be sure. Heat builds up slowly if it's not instantly burning.. I don't know how much heat your 1000w lets out, but my 300w starts damaging the plant at around 10 cm, so I keep it at minimum 20cm away. So your 1000w probably shouldn't get closer than 30cm, while 40 - 45 is probably better.
- Though, measuring the heat with your hand will get you a better idea.. Just test it out at different levels and fins out what suits you. ^_^

I would put it to where the back of your hand is comfortable under the light for a minute. Meaning no strong light heat hitting your hand. Cheers friend

My Girl's Gone Rogue with 10cm of Frosty Goodness!My lady decided to shatter the whole "week 10 harvest" and instead shoot 10cm, packing new flowers whiter than a yeti's behind in a blizzard!
This genetic curveball beats me.
Do I let her keep this frosty stretch, or do I harvest and let this mutant masterpiece become a solo act

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Day 49 autoflower huge and not yet flowering. Help!Day 49 autoflower not flowering? She's huge and I'm running out of room in the tent (58" and my tent is only 6 ft). Should I flip the tent to 12/12? Do I then keep it 12/12 the rest of the grow? How will that affect the Day 30 plant? Should I add 2nd light for smaller plant?

Foxtail Ready For HarvestHello. This plant of mine became foxtail. As the harvest time nears its end, blooms have begun to bloom again on their hills. Now the first flowers at the bottom are ready for harvest. What should I do? Should I harvest immediately or wait for the new flowers to mature?

18 weeks, but I'm not sure she's ready.The plant is 18wks old. Leaves are getting yellow, some buds are so fat the branches bend under the weight.
I'm worried some pistons are still white and I can still see some clear trichoms, but she's 3 weeks after the recommended date of harvesting.
Do you think she's ready?

Why dont my plants grow towards the middle/light and instead concentrate near the walls?Looks like my plants are growing towards the wall and not towards the middle where the light should be the best.
Why do the plants behave like that and what should I do?
Raise the net, rotate some of the plants, then redo the net?
Remove the net completely?
leave it as it is?

What do you guys think?It's my first grow (automatic, 6 weeks old) and compared to other plants, my plant looks a bit small/ridiculous. I give her 24/7 light (I read that on guides) is that maybe too much? What's your impression of her? I use two growlights (one from above and one from the side).
