Second Grow/First Time Starting From Seed

You should really never be growing inside a structure without some way to move fresh air through the space. You are asking for all kinds of problems..
Runaway temperature swings, humidity spikes, mold... you really have to move some air.

Would something like this work? Or should I use this tent with one of the lights already recommended?

Hey guys,

So here’s my update and I have a big question. I got a new 2x2x4 tent. I’ve attached pictures.

1. My largest seedling has a brown leaf.
2. Most of my leaves look like they are curling down(on the bigger seedlings, the smaller ones don’t look as affected. Is this overwatering?

How often should I be watering these? I’ve been doing once a day with small run off. It’s mostly just perlite with rock wool cubes all the way at the bottom. I’m trying just to water enough so the rockwool is wet once I feel it’s dry through the bottom of the cup.

Temps and humidity seem to be fine.

Should the light be any closer? Or is it fine for now. It’s about 24-30 inches away. I didn’t really measure

I do have a 15inch fan outside the tent circulating air. It seems to be working for now. Will get it exhaust fan next

nice little setup you got going bud. Is that the Optic1XL? 54W or 100W ?and for the watering bro, you need to water it several times a day, or even dripper to be honest. First grow, Id go with soil or cocoloco. They look hungry. Cocoloco you water when it starts to dry, and it forgiving so you can let it dry almost totally, or water everyday if you want. The perlite mix just doesnt have enough to hold water and drys out super fast. so basicly, all the roots that grow outside the small rockwool air prune themselves and just cant eat nutes living like that. If you want to go the solo cup route start to finish, thats fine, but for ease and risk of failure and stress, get the cocoloco bro, zon has it for a great price, but its a large heavy box, and your mailman will hate you,lol.. You want EASSSSSSEEEYY right now. everything else is on point. If you can afford it, Id do it right the first time, get the SuperRoot airpots from the zon, even 1 gallon if you want to stay small pots, get the cocoloco, and get megacrop nutes. super cheap for all those, but tellin ya, you will love it, and it wont be so stressful on the mind.

your almost there bud,

This is my #1. My grow progress is all over the place. I think I might have put too much shock on all my plants and growth is pretty minimal. But I’ve taken everything I learned from everyone and started some new seedlings and they are fucking growing! More growth in 7 days than the whole month on the other plants!

I do have a question. Do the cotyledons turn yellow and fall off on all plants?

I also have some yellow-lime green “slightly” drooping plants. I’ve been laying off the water. But not really seeing it bounce back.

lookin hungry again man, or needs more light.

I've never seen an all perlite grow either. Besides weak lighting maybe this is a big part of your problem? I'd suggest adding in some loose coco coir to fill in the voids and give the water something to absorb into and to promote root growth. Speaking of root growth... look into adding some "great white" into your feeding program. It will help those plants really take off.

T5 is a very popular option for vegging out the plants. I'm trying LED boards from Horticulture Lighting Group and am very impressed with the results so far. A picture of my garden exactly 1 month from dropping seed into water. I'm growing in coco and transplanted this morning from a 16oz keg cup to 1.5 gallon pots.

Very nice! I posted a few days ago with my new light, cococoir perlite medium and tent.

Would this 600 watt LED be a wiser choice than this 75watt cob?

Is this 600 watt too much for a 2x2x4 tent?

That light is not 600 watts. Here is a quote from the amazon listing for that light that you probably missed.....
"COMPARE TO HPS/MH- The 600W LED grow light can replace traditional 400 watt HPS/MH while consuming only 108 watts!"
So yeah, there is red flag #1... call a light that pulls 108 watts from the wall a '600 watt grow light'.

A high quality 75 watt COB will completely out preform that piece of crap blurple.

Ok so my next question is, I bought the 3k Cob. Should I get the 4K or 5k?
And it didn’t come with a reflector like advertised.

Sorry, may have missed it earlier in the thread... what COB did you buy?

Lol you quoted the answer. I bought the 3k. I want to know (sorry for the confusion. There is no 4K it’s 3500k.)

So is the 3k fine. Or should I have went with the 3500k or 5000k

I'm asking for information on the model and manufacturer.

UPDATE:

So my plants looked absolutely great 3 days ago. I watered them with 3 tablespoons of my nitrogen solution per 1 gallon of water in 6.0 ph balanced water. So then two days later it looked to me like a potassium def. so I gave my my plant THE SMALLEST drop of 4-8-2 solution and now they look like this. Maybe that wasn’t the best idea? So I gave them some Balanced ph water and that was it and this is what I have.

So what should be my course of action be?

I’ve attached all the pictures on all the problem areas.

I also am concerned that the internode stems are turning purple? Which also made me think deficiency.


And I took a light reading. Is this good or bad?

Here’s where we currently are a few months later. I ended up throwing away most of that batch since I think I shocked almost everyone to it’s last moment on earth from being ignorant. But we are in the last half of flowering. I threw another plant in the flowering tent just because I didn’t have enough space to put it back in the veg tent and I honestly wanted to see what It would produce compared to my larger plant.

But yeah, I think I’ve pretty much got the handle on this shit now. Now I just need more space and time I’ve done nothing short of research this more than I studied in HS period haha.

I’ve also been trying multiple pruning/topping methods in my veg tent.So I just had a bunch of seeds so I took the time to dedicate each plant to a different experiment. Have a sour diesel that is hating my guts from the mainlining, but it looks so frickin cool.

Not looking bad now man, I noticed you're cob light was looking really far away at first try to keep that baby a maximum of 18" away bud. Hlg and rapid led are great companies for lights I would hang a 75 watt rapid led beside you're cob to really improve quality. Have you made a ghetto c02 generator for the room.. if not look up c02 generator on YouTube.
