For just a few plants you cant go wrong with one 250 watt HPS.Overall they are better than a halide,especially for flowering.Just hang in there until you can get your light. You will see imediant results.Also,check your Ph.Keep it just a bit acidic,around 6.6 -6.7.Do not water every day,only wate when soil is dry.Too much water can can really mess your plants up.
