Need Help with HEAT.
Most cannabis actually comes from temperate areas in Asia. The plant is built to cope with cold winters, thus its habit of 'annual' behaviour, where the plant produces seed then dies. The seeds carry the DNA forward through cold winters without the plant itself having to survive. Places with cold winters often don't get very high summer temps, usually for just a few weeks. True tropical plants, capable of 85F averages, come from places where there may only be 2 seasons (wet & dry) and have very different propagation habits, often being perennial or not dropping leaves in an autumnal season.
Cannabis plants start to display longer internodes at temps 80F and over (85F with CO2). This 'stretchy' habit will appear in buds as thin or spongy growth.
If you want tight, dense, solid buds, keep the temps down. 75-77, 80 on a bad day.
You're right, the setup of a grow op is the most expensive. Those who buy kits get socked the worst. If you are handy in the workshop, learn the operating theory behind what you'd like to use and DIY/build your own stuff wherever possible. I've seen $300-400 aeroponic kit systems duplicated for under $50, much less if there's junkbox or op-shop materials available to recycle. $50-60 spent at the local hardware and an hour spent in your workshop will make you a nice efficient batwing reflector that would set you back at least a couple hundred.Al B. Fuct Reviewed by Al B. Fuct on . Need Help with HEAT. Where i live is very hot during the summer. I mean really hot, like 120F. for a month hot. When it is this hot, my house is about 85F inside. Now I have a 5'X5' grow room, with a 400 wat HPS and 6 42 wat cfls, and a t-15 tube light, with good venting, but if I am pumping in air at 85F, how do I keep it below 85F with out killing my wallet? I saw a small swamp cooler at Lowes for $250. this would help also with the humidity, it goes at about 30%. Any ideas on a way to keep this room cool with Rating: 5
