Hey ms. Thanks.
The coco is a bit of a mixed blessing for me. I was expecting it to dry out rapidly but it doesn't work quite like that. I guess it encourages root growth and when the roots are suitably big they suck it dry quickly, but for little seedlings with no rootmass it just stays damp...
Welcome Enjoy! and thanks for the comments.
There's a few issues I didn't anticipate when I changed to coco for this grow but I think the redness is from some pretty cold weather recently and the yellowing is mostly from cal/mag def. I only ended up cutting the main cola last night and the plant...
The heatshield is a great idea, but you will need to rig fans above it to provide the cool air and exhaust as maturesmoker says. Here's a pic of my case to show how I do it.

There's 2 ways to make fans silent. One way is to spin them slowly and this produces amazing db stats but even the latest akasa apache only hits 50cfm. Once you factor in very hot air and lightproofing/odour control this drops to nil.
Unfortunately these fans can't be turned up because they are...
Cheers Tom. Good call.
I think I've sorted it now but these plants hate sitting in damp soil so I've had a nightmare trying to feed them while they are young. They just show heavy overwatering symptoms the moment I feed them!
I think they would be better suited to a flood and drain system but...
Usually the lower wattage sodium bulbs are Low Pressure Sodium (SOX) and not High Pressure Sodium (SON). If you look at the output they are very unusual as they emit all their light in a single frequency, normally either 1950K or 2100K IIRC. This is why I never tried them in my case as they are...
Just a quick update. I've been working out the kinks since I took out the cfl's and fitted a cmh in the case. I got a new acrylic sheet today to replace the old one and when I fit that later everything should be done and dusted.
There's a small batch of NL's in residence just now. They've been a...
Hey Xa. Sorry to hear about the delay.
I know it isn't much help, but plants and soil both absorb some heat and you'll find that temps will drop noticeably when you get some greens in there.
Let me know if there's anything I can help with.
Hey Xa
Good to hear you're almost ready. The ph pen will be real easy to use, a good investment for sure.
The blutack is great stuff too, I'm sure my case would fall apart if I removed it all :)
Sounds like there may be a business opportunity for you there.
I use a black case and only need...
The bulb in the link looks a little expensive. Those bulbs are available in Tesco, Focus and Wilkinsons for a fraction of that price. It looks like you are paying for the ability to dim the bulb but it's unlikely you will need to do that.
Here's a link to bigger and cheaper 2700k and 6500k bulbs...
Hey ms
Couldn't let this thread go without posting up a pic of my little effort.
Got various probs to sort out before I'm happy with all the recent changes. I've also got some new seeds to replace these NL's as they all showed deficiencies & poor growth, but for what it's worth here's the...
