Tried
Google Calculator? It does some amazing shit, not just simple maths, not just metric-imperial conversions, either. You can convert litres/100km into mpg, ml/L into oz/gallon, etc. Ever wondered
how many smoots in a furlong? Wonder no more.
oh yeah.... a very necessary maintenance job with drips.
Yes, and for almost all situations. What medium are you using?
Too close for just about anything but a 400HPS in a cooltube.
Got pix?
It's probably time to start over, but I'd like a look at this plant if I can get one.
Hugely lucky. Surprised this isn't killing them outright. RW
must not ever be allowed to sit in a puddle of water, nor be watered frequently or for long periods. It is highly absorbent and saturates in seconds. This drives all the air out of the material, necessary for root formation. RW must be kept damp, never wet or saturated. If you have slow development of seedlings in RW cubes which are kept in a puddle of water, you now know why.
Because of its high absorbency, RW is generally incompatible with drip systems, unless the drip feed runs for only a few minutes, 1x/day. Handwater seedlings or clones in RW cubes by dipping a corner of the cube in pH adjusted water (5.8 ). It's the best way of gauging how much water they are allowed to soak up.
Once you have roots out of the cube bottoms, the cubes can be put in pots of pellets. The drip system should then be organised to water the pellets only, never the RW cube. Drip rings are well suited for this purpose.
