  1. 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 You may also want to consider choosing plants that colour up in moderate light - some are more fussy than others
  2. 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
  3. 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
  4. 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. Consequently, I just bought another identical MarsHydro and will be replacing it this week Hope that helps, Dave
  5. 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
  6. 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 mounted into the lid of the propagator about 15 inches from the foliage. Out of the box, it provided 45000 lux @230watts, but the its wattage can be adjusted down which I have done to about 19000lux @90watts directly under the lights, to about 10,000 lux in the far corner of the propagator. It’s a white spectrum light but claims to have a good PAR rating. As its size and shape fits the unit well, the light is reasonably even within the grow space – much better than my other propagator with a smaller light where the difference between lux in the centre and corners of the unit are 5x compared with this at 2x
  7. 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
  8. 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.
  9. 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
  10. 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 producing 20ppm within 10 minutes. We do have very high water pressure here, though - I wondered if that was possibly a contributory factor for you?
  11. I have managed to get through 2000 litres since the last rain, I thought I was covered with that amount of storage, but apparently not I have heard that RO membranes clog if not used for a period of time. In other words, that a unit cannot simply be mothballed - once you start using it you have to keep it going (or replace the membrane before you can bring it back into use) Does that sound correct - I don't mind investing in a unit, but having to replace the membrane at the end of using it for a few weeks a year makes it quite a high cost of use solution.
