Growing in a uninsulated room next to two external...
NuiUKstarted grow question 3 years ago
Growing in a uninsulated room next to two external walls. It's gets very cold or hot.
Considering insulating the entire room using PIR insulation board that ranges from 50-100mm in thickness. Can anyone share some advice on board thickness/what to use and why.
Thank you😊

More insulation is almost always better.
My grow room has three exterior walls and they are insulated to R25. Originally it was only insulated to R5 but I had to use a lot of heat in winter. When I increased the insulation to R25 it was immediately noticeable and maintaining temperature in the room got MUCH easier in both summer and winter.

It would be easier to go with HID lighting in a cold space, especially since you have external walls that you can vent the heat out through and a heater, in the room for lights out, to keep the room from getting to cold.

Soundproof grow areaI made a countertop tent out of mylar and 2x2s. Any tips on what I can hang on the front to dampen the sound of fans and filters? Foam didn't do much so I broke it into smaller pieces to block off the noisy fans and pumps individually. I'd like to isolate the whole thing ideally.Week 3

Auto flower?Out of all my plants only the one of them has really shown this much progression with flowering sites. Is it flowering already before I switched the lights? If so does that make it an auto flower? Also will it hurt my plant to have not changed to 12-12 yet?Week 7

Newbie OG Kush Fast - slow growth help!My fast OG seems to be behind schedule at 2 weeks compared to a lot of grows I've seen here. 😕 I am new and can't put my finger on what I need to do in order to get the growth even after reading a lot here so far. I'm still bad at pH balancing, I think. Any ideas? Thx!! 👍4 years ago
