Tip 1 - Lamps
Lamps can greatly lose lumen output over the course of 9 months to a year. In fact, they usually depreciate in lumen output by 30% over this time frame. This means that you will get 30% less yield from your plants but it is costing you the same amount of electric to run them. It is therefore a false economy to run old lamps.

Tip 2 - Seedlings
When using rockwool to raise or start seedlings; make a stock solution using your grow nutrient or similar to a TDS/CF reading of 10-12 then pH adjust that stock solution down to 5.5 pH. Decant this solution into a bottle so you can feed this to the rockwool as and when needed. Shake bottle well before sprinkling. Do not over soak or let rockwool sit in a puddle of nutrient.

Tip 4 - Don't over do it
Less is best; the name of the game in hydroponics is to never over do it. i.e. under feed them, under light them (within reason), under do it and you'll get a result, over do it and problems will happen.
