  1. I grow sarracenia seedlings with full spectrum LEDs (MarsHydro SP series) between 10,000-20,000 lux with 18 hour days. They grow strongly and with great colour.
  2. You are right you need lots of light. Blurple lights will look horrible in a domestic setting, so you probably want a white light. Have a look at Mars Hydro, I have been pleased with them. Even then if the lights are really bright in a window that is going to stand out from inside and outside the house. You may get planes attempting to land or strangers asking if you have any cannabis for sale. Two other considerations - you need to find a way of giving the plants a clear winter rest. Some people cut off all the leaves and put in refrigerators. Its brutal, but it may be an option for you
  3. I bought an affordable Light meter (ETI-1301), but I'm sure they are all much of a muchness I use it to judge light levels broadly, and make comparisons. I understand that PAR/ colour temperature add considerable complexities
  4. It is also solid (plywood). & the whole inner face of the propagator, including the door, is lined with Hydrogarden Orca The lights are very bright, the whole thing would stick out if any part were translucent
  5. I'm pleased with it Sarracenia seedlings are growing and colouring up nicely under it (which you can actually appreciate compare to blurple), it's heat burden is low, there are no active cooling fans to go wrong, I love the adjustable driver, and most importantly it lights the space evenly. I have another propagator of a similar size that I have been lighting for a couple of years with a 'Platinum LED' P300. It's a great light, but it is 13000 lux in the center down to about 2000 at the edges, so it doesn't light that space effectively. It would be fine in a smaller space.
  6. A 90 watt draw MarsHydro SP250, with the transformer and heat sinks outside is enough to raise the temperature of a well insulated propagator 140cm x 50 x 60 by about 20 degrees . Hope that helps
  7. My project over Christmas was building a new propagator for bringing on Sarracenia seeds. It is built with 18mm varnished plyboard, with 50mm foil backed insulation on external surfaces and under the base. Internal grow space dimensions are 54 x 140cm. Total height is 60cm to fit under greenhouse benching. Inside is lined with Hydrogarden Orca grow film, which is highly reflective but gives a white diffuse light and is a useful tough cloth like material to work with In the base is a thermostatically controlled Bio Green Sahara heat mat. Lighting is a MarsHydro SP 250 mou
  8. This my favourite clone, deep red colour and full, rounded flower. It's quite a contrast to the other clone I have with strongly reflexed petals
  9. Hydrofoggers, like these: http://simplycontrol.co.uk/shop/hydrofoggers/2_44_0_274/hydrofogger_400.aspx ; https://www.hantsflytrap.com/hr50-humidifier-hydrofogger-500-p.asp I combine them with extractor fans, keeps a south facing greenhouse cool and humid.
  10. Cheers, I'm all OK now. I plan to buy a flush kit, in which case I think I need to open up the elbow and remove the inbuilt restrictor anyway Probably get a pressure gauge at the same time, if that's a good indicator of clogged up prefilters
  11. I bought, perhaps hastily given your subsequent experience but I was starting to feel a bit exposed without a backup plan, from the same vendor as you, except my unit is the 100GPD FS-401 http://www.pure-pro.com/fs401.htm The lack of instructions were a bit troubling, and the single sheet that does exist refers to a flow restrictor on the RO water outflow elbow that could be inside the unit but is not at all obvious. It also includes some unexplained components which I believe are intended for attaching to garden or kitchen taps Anyway, I did simply connect it up and it was produc
