2 hours later:
1F degree higher and RH is holding steady.
ok any help appreciated. Having issues regulating the heat and getting ideal temps and RH and dealing with a possible stunted plant...Maybe I’m just being too picky...Lights out temps are around 68F to 71F with RH around 50-65%. Lights on temps are around 79-84F but mostly always on the higher end tho which I feel is my issue. Lights on RH is around 40-50%. I just can’t seem to keep temps under 80. Ideally I’d like 77-79 with 55% RH until flower.
So I have a 4’ish x 4’ish x 6.5’cish Grow Box - guts are green board painted with exterior paint, caulked all joints and sprayed foam insulation on all joints, added roxul insulation, sealed it with vapor barrier, then final layer is reflectiv radiant heat barrier. It’s fairly air tight minus the 3 intake holes.
Room Accessory Details:
1) 6” Vortex fan running full speed with a 6” inch exhaust hole running 19/5
2) 600 Watt LED running on veg and bloom running 18/6
3) Air humidifier running 24/7 (or until water runs out)
4) 2 oscillating fans (one mounted on wall just above lighting which runs 24/7 and the second one sitting on the ground which runs with lights on 18/6).
5) Two glass jars of water (increase humidity)
6) SensorPush thermometer/hygrometer to grab ambient temps/humidity - placed opposite vortex fan in top corner.
7) Basic thermometer/hygrometer hanging beteeen plants shaded by the lips of the pots.
Three - 4” intake holes (one connected to outside vent to bring in fresh cold air using the negative pressure). It’s dang cold here now so the air is probably fairly cold when it finally hits the box. The vent ducting runs about 15 feet from the outside vent entrance to one of the 3 intake holes. I have bug mesh and HEPA filters covering all 3 intake holes, my exhaust exit hole and my fresh air intake hole. I don’t have an intake fan, though I think if I hooked one up to the fresh air intake it this would help bring in a lot more cold air into the box and drop the temps to where I want them to be. Not sure tho.9) Light and exhaust are on at same time and I have one os fan set to come in with lights and a second os fan on 24/7.
10) Four - 5 gallon pots (2 of them are Redi-Root cloth pots set inside Redi-Root pot frames and 2 Vivosun Fabric Pots. I have all 4 cloth pots wrapped in Gnatty Nets.
11) All autos: In one Redi-Root I have 2 Dark Devils, in the second Redi-Root I have 1 Meph vs Alien. In the Vivosuns I have 1 Diesel and the other Bloody Skunk.
Meph vs Alien (DOB November 30) seems stunted or a bad seed but I can’t figure it out. Diesel (DOB is November 29) is going good (I think) but since it’s my first grow not sure what/how to compare it too. The two dark devils (DOB December 6) are coming along nicely now (first seed I messed up and pulled it to start over and figured I’d do two seeds in one pot to make sure one of them grew). I am also banking on the fact that since they are autos they will not need to sit in the pot too long and have their roots get all tangled - fingers crossed). The dark devils are about a week behind the Meph vs Alien and they seem to be catching up based on size. The bloody skunk (DOB December
is very new so nothing to discuss on that one.So that is my second part concern of this post. Why is the Meph vs Alien growing so slowly? Maybe I’m just being impatient. Is there a guide anywhere showing average heights for plants at different parts of the plants life?
Thanks in advance for the help. Apologies for the long post but wanted to make sure I covered as much as possible to get viable answers.
So my questions are: how to drop lights on temps 3-5F. If I can do that i think the RH will get to where I need it to be and is the plant stunted?
PS Will take pics when I get back home and post up for review.
