First closet grow - seeking advice

[aussiedude]

Wow thats a big difference to mine. Are mine stunted due to spending their effort on stretching?

Thanks slonez, I think my plants are having heat stress they have these yellow burns on them? Are they burnt?

Are you spraying them with water? if you leave water droplets on the leaves that'll burn them too. Let me check out a book that I have and maybe I can give you a little better answer. With seedlings it gets a little tough sometimes because there are mobile and immobile nutes and they'll affect the new growth or the old growth and that narrows things down a little better.

Yes. They're growing, but in the wrong direction.

They haven't had any vertical growth for a couple of days now, hopefully they are putting down some roots!

I have been spraying them with water although very sparingly but yes sometimes droplets have been forming on the leaves!

Sorry brother. I got side tracked. My friend came over and we blazed. I'll look that up for you as best I can. In the mean time you might want consider soil if you have'nt already tried hydro. I can't see how you could though. You'd have to wrap the stem around the net basket. lol

I've lowered the lights a few cm. New pic posted.

Also the leaf discoloration pic wasn't focussed properly so I have taken another pic hopefully its clearer. The leaf is turning yellow a tiny bit

The seedling on the left in the pic is a THC Bomb (Feminised) and the other two are Himalayan Kush (ordered from weed-seeds.net)

I can see water standing on the plant stem and leaves. That might just be the big part of the problem aside from the stretching. Burying those long stems is your best solution for them. IMHO

Seedling stage IS where they're busy putting roots down and veg growth is slow. If the plant has to concentrate on reaching light it only stands to reason it's slowing root developement and stunting that growth. Then it just spirals down.

Thanks for the information slonez! I have a pot for them with some clay rocks. My theory was to wait a few days before putting them in (and burying most of the stretched part) and strengthen the stems because I am not sure that the clay rocks might crush a fragile stem.

I've just finished the intake ventilation (attempt#3). This time I have gone to the source and cut a hole in the floor. Temp is 20.5 under the light! I still have the door open and its not air tight but its getting there!

Is your cool outside air coming from that big vent you have mounted next to your plants? I'd have maybe put that closer to the floor. I saw what looked like a vent leading out of the ceiling too. I'm not sure but that would restrict your hot air exhaust from the room. I know in piping that you increase flow by making the pipe increase in size not reduce. Instead of having negative pressure in your grow room it'll be positive and blowing outward inside your room. Does that make sense?

 

[slonez47]

You won't be exhausting your hot air as fast.

 

[aussiedude]

Yes, the 200mm ducting (the black one) is my cool intake. The ducting isn't fixed at the moment, I just have it blowing the cool air on the plants while I keep working on fixing my exhaust. I was planning on chopping the 200mm intake where it pokes through the wall.

The ducting going up to the ceiling cavity has two 12cm fans (pretty noisy) running but I'm about to redo that so the pc style fan is mounted to the roof of the lower chamber.

I think I understand what you mean? Would it be better to replace the exhaust ducting with a 200mm fan also?

Testing new exhaust setup. Seems to be working pretty well at the moment, but it is very cold outside. Will see how it goes tomorrow. Summer is going to be a bitch, I think I will have to get a portable aircon :-/



Going for the stealth look.. The PC case is temporary (thats a queen size blanket stuffed in there for sound proofing hehe)

P.s. Sound proofing stuff is hard :-/
Can still hear the ballast and the new exhaust fan

Are your exhaust fans hard mounted to wood or metal? If so a rubber gasket between might help with dampening some of the noise. I've also heard people building a small containment box for the fans, a sort of second wall.
