New at this Please help

:rastasmoke:I started 2 plants by curiosity. Now I think im hooked on this. I developed a green thumb. I have thought about doing this in the past but now im in a position that it is easy for me to do. Stelth is not a factor.

but,..

Im new at this. I have invested some money building me a cabinet to hold these. I build a 36"x36"x9' cabinet. Hoever i see that I have made a small mistake by not using a smooth reflective material on the inside.

first problem I would like to fix is that I have some yellowing leaves.

Location of cabinet in in my garage. temp does fluctuate about 20 degs.

any help?

first off, do lots of reading, there is a troubleshooting form you can fill out to help with the yellowing...you need to provide LOTS more info. a 20 degree temp change isn't too bad, as long as its not super hot or super cold. i believe i read that photosynthsis happens best between 75-80...

Hey thanks for the info,

I will give you the skinny on this. I started this because I now have the space and privacy.

I built the box from 2x4's and 1/4" plywood in my garage. I insulated with a reflective padding. my thought that this material is shiny and insulates well. I also sealed the ouside so no air can get in with out going through a bathroom fan with a speed control. I used a 4" dryer hose to suck air out.
winters get brutal here and i want to solve this problem before it gets to cold and i kill them.
I used a spce heater in a fire safe box and set the thermostat to keep at 80 deg. my first question is :

do i need to add humidity to the air once it has been heated to 80 deg.

second im using a humidifier to add moisture. can there be too much humidity?

and lastly. can there be too much air circulation?

Thanks in advance

pictures dont laugh

No laughing, promise! That's cool.
Suggestions:
-Your light needs to be adjustable so you have it RIGHT ABOVE the plants at all times, and when you switch to flower you will need more light, like a HPS400. Flouros can't penetrate a deep canopy like HPS can.
-See if you can control your temps through different vent configs/schedules and possibly the addition of a SMALL space heater for the 'night' time. Keep the swing at about 10'. This is good for 3 main reasons, including preventing dewfall and mold, reducing stress, and keeping the plants from stretching too much which they do with a big temp swing, and you can't afford stretch under flouros because of the canopy penetration.
Nice work, keep it up!
