So i have my 5 beautiful ak-47xdiesel females at about 3wks of flower in my 55-70%RH basement under a 400w MH. My question is should i invest in a dehumidifier or get the 400w HPS conversion bulb? I dont know which 1 will help on the long run and i have abour 1 mth left b4 harvest....NE ideas?
If you are asking if it were me, well i'd go for the dehumidifier. With your humidity getting as high as 70% isn't good when it comes to near harvesting. You would do better with the humidity down to 30-40% in your last weeks or two. Budrot is a bastard, my friend had bad budrot (by bad ventilation), for the amount of bud he lost, he would have bought himself 5 exaust kits. I would finish out this grow with the MH and dehumidifier, and buy a HPS (or conversion) lamp for my next grow.
Great advice john. My first thought was to get the conversion, but you make a great point about the humidity. My basement would be 95% humidity without the dehumidifier. Luckily we just got a new one, uses less energy, more efficient, not to mention it weighs less and has built in wheels.
watch craigslist if you have one in your area, I find quite a few on there when I need another, good choice on getting the moisture down before lighting also, nice call on Johns part, I must be lucky cause this grow I haven't had to kick on my dehumidifier once still about 45%, check this nuglet in her last week of growth.
